Title: Air Brush and Compressor Discussion Thread
Post by: alphabeta on March 13, 2011, 01:23:43 PM
Looking to purchase my first airbrush outfit. I am looking to spend up to $800 to get all the equipment I need.
I have built a spraybooth at work,so the compressor has a dedicated environment which it will stay in.
Will be used for gundam and smaller scale kits,nothing that will need litres of paint  :)

Have $800 ready to go,but if there is something you feel is must have in the set up purchase-please let me know
and I can stretch the budget a lil further....( famous last words  ;D  )

Pro's/cons of different styles of equipment,and real world experience and suggestions are greatly appreciated.

Hopefully we can nut it out,so I can stop spending so much on cans..

Thanks,Mick.

I use a 30 year old Badger 200 and a Scorpion compressor that cost me less than $100 if that's any help. ???

Hobbytools.com.au (http://www.hobbytools.com.au/) have a great range at reasonable prices.

 For $800 you will buy a cadillac of a setup. Go for a compressor with a tank as this will give you uninterrupted air supply and plus they run cooler as they are not constantly running, and go for a double action, gravity fed airbrush.

Don't buy the most expensive one they have because being your first airbrush you will probably mess it up at some stage.

I have a sparmax compressor and AB. Not that great for really fine detail but they do the job fine and from memory set me back under $300.

This compressor (http://www.hobbytools.com.au/prod870.htm) comes highly recommended by at least two of our forum members, at a great price.

Compressors page (http://www.hobbytools.com.au/category83_1.htm)

Airbrushes Page (http://www.hobbytools.com.au/category56_1.htm)

Accessories page (http://www.hobbytools.com.au/category59_1.htm)

Depending on which compressor/AB or package you buy, your compressor and airbrush may or may not come with the fittings, hoses (http://www.hobbytools.com.au/prod902.htm), filter regulator, moisture trap, pressure guage (http://www.hobbytools.com.au/prod1329.htm) etc that you need. Make sure you check the listings for these things and also to make sure the fittings match in size bewteen the compressor, AB, hose, regulator etc and you won't need an adaptor. Common hobby size is 1/8th of an inch, tradesman size is 1/4 inch.

Also worth a purchase is an airbrush holder (http://www.hobbytools.com.au/prod1102.htm) and a cleaning pot (http://www.hobbytools.com.au/prod919.htm).

You will blow $800 easily at that site so my advice is to stick with the bare essentials first off and then figure out what else you think you could do with later.

Sonar-thank you very much for your detailed response.
The Artlogic compressor is a great price,great tip.I can see what you mean about spending some
$$$ on that site!

Exactly the kind of info I was after mate,I made mention of my budget as I truly was not aware
of the cost in starting out.

Thanks again.

$800 ?! @__@
Wow! Wish I had that kind of money when I was building my gig.
From memory I've spent total of $400 by buying 2nd hand pieces...
Was under strict condition set out by missus so couldn't really afford shiny new gears~ -__-;

Last time I ever mention money here !

I am 35,father of three,and own a successful mechanical workshop.
I don't like to stuff around buying gear twice-spend it once,do it right.
That wont resonate with everyone,but it is the code I live and spend by.
Again,thanks Sonar for the clear and useful advice,will update on my purchase when I decide.

Of course a donation will be made mate.
I have already donated through a largemouth bass forum in JP that I have been a member of for a long time.
My wife last night made a donation to the Japanese red cross as well on behalf of our family.
Will do same here on Thursday.

Just get a simple air compressor from Ebay, Got mine under $80 delivered.

As for Airbrush!!!
Here's the most tricky bit.
I found myself loving Single Action rather than the double action type regardless whether it was gravity feed with the cup on top or sipone from the bottle at the bottom.

You need to know what works for you in the end, as I have an Iwata just sitting around as I found more disadvantages using it than a simple reliable Single action one.

You probably need a double action airbrush to do certain things better but for basic painting, I just love how single action works, and is easy to clean. I could almost see why some people gave up using airbrush for priming, and then painting. It takes up a lot of your time.
Title: Re: Airbrush set-up ?
Post by: mokana_man on March 16, 2011, 09:58:34 PM
I'll throw my two cents in, get a cheap-ish single action for primer and make sure the compressor has a regulator and tank the other bits are standard. Check out the Iwata brand of double action air brushes for 80% of your regular painting.

That will cost around $500 but feel free to pick up goods like glass eye dropper, 2,3 or 4 way taps to hock up muilitable air brushes, several mini metal trays for mixing paint, air brush stand, self cleaning pot to remove waist, 100 bamboo kaba sticks and alagator clips (to hold your model pieces), air brush parts (eg. needels and nozles), cleaning thinner. These bits and pieces makes the job much easier and all are under $10 but together adds up.

If that left over money is still burning a hole in your pocket pick up a Tamiya spray stand and a sonic wave cleaner for maintenance. Excluding the cleaner this is what I have and am able to pick up a brush and start painting with in a few mins...

Also to add, for the cheapo airbrush make sure is NOT PLASTIC, it will break. I havent get the hang of enjoying double action airbrushes, is probably me getting use to it.
Just find it a bit too tedious to open up, clean needle and clean the whole interior after every job done for double action airbrush, not sure if anyone feels the same. Love a good quality Single action airbrush which was almost no brainer for me (which is why I say its a good beginner airbrush to start with). Again I believe is upto individual of which airbrush they prefer, I certainly feel happier using Single action to begin with and then go advance from there.

As for the aircompressor, it needs the water trap filter as well. Which I was lucky to get such a compressor for under $80 delievered.
Not forgetting Teflon plubbing white tape to ensure good fit at the hoses.

Thank you very much mate,great that you considered my question worthy of such a detailed response.
Exactly what I was hoping to hear.
I had'nt considered a 2 gun set up,with the cheaper for priming,but it makes perfect sense.
Will update here once I make my purchase.Might be getting a compressor through a contact at QLD Trade tools.
All of the advice shared by all has been very informative.Thanks all.

I'm thinking of getting one of these air compressors from ebay:

http://www.ebay.com.au/itm/NEW-1-6HP-AIR-BRUSH-COMPRESSOR-SPRAY-GUN-TANK-/190537994981?pt=AU_Toys_Hobbies_Model_Kits&hash=item2c5cf312e5

It may be the same type as drifand mentions above, I'm not sure.  At any rate, it says it has an air filter which you can see, however is that different from a moisture trap?  I'm unclear if I need to buy one separately or not.

If I do, is something like this sufficient:

http://www.ebay.com.au/itm/AIRBRUSH-MINI-AIR-FILTER-Moisture-Water-Trap-Spray-Gun-/330497993610?pt=AU_Art_Supplies&hash=item4cf3372b8a

Title: Re: Airbrush set-up ?
Post by: TheGhostofZeon on May 29, 2011, 08:12:50 PM
I have one of those moisture traps (which I got from Runway13) and it is one of the best investments I have made. My compressor is getting on and runs really hot after a while and when the hot air enters the air hose, it cools and moisture forms which is a pain when it blows through the air brush and onto the piece I am painting. I read up about moisture traps and everyone says that they are better at the brush end rather than the compressor end.

I got mine a few months back and it is amazing the amount of water that collects in the thing. Since I have had it attached, I haven't had any water spurts at all.

That compressor will do the trick too - just remember that it is on the cheaper end of the scale so if it breaks down don't be suprised.

Thanks Ghost.  Yes, I realise it's a cheapie compressor but I found a couple of people in other forums who had purchased one and asked them about their experiences.  So far they say it's being doing the trick and is good bang for your buck.  I've decided to take the chance.

With regards to the inline moisture trap I linked to, it says it is also an air filter, but the compressor already comes with an air filter.  Will having two air filters be a problem in anyway?
Title: Re: Airbrush set-up ?
Post by: TheGhostofZeon on May 30, 2011, 07:42:15 AM
It says air filter but it more means it's an air filter that removes moisture. The air pressure hasn't changed on mine and if it has then I can't notice it at all.

Lets us know how you go with the compressor. I'm interested in finding out how they go as well.

Are you referring to the compressor air filter?  As in, I don't need to buy an additional inline moisture trap?

It'd be nice to have an Airbrush General Q&A sticky in this forum I reckon :)

I've been thinking about getting into airbrushing myself, but finance is a little tight. I'm sort of stuck in a tight spot. I want to paint my future model builds, however cans are absolutely not economical. So it seems the only two choices for me are: airbrush or hand painting. So right now I'm really just trying to figure out how much a decent beginner airbrush kit will cost and then I can decide if I will make the investment!

I'm new to this forum and haven't contributed much, but just wondered if anyone could link me a nice airbrush kit for beginners. I prefer buying local (Perth, WA) because then I don't have to worry about shipping times, warranty, things breaking and having to wait etc. but I understand the modelling hobby isn't exactly huge and online may be the way to go. I've had a look at this kit:

http://www.hobbytools.com.au/prod192.htm

What do you guys think about that?

I would be happy to put a bit more effort in and buy parts seperate for my airbrush kit as well if that means I can get better stuff suited for gundam modeling. Would like to limit my purchase to $250 for everything required for airbrushing, however if justifiable, I can stretch that budget :)

No, I mean that the moisture trap is also an air filter but for moisture. The compressor filter will clean the air but not remove much if any moisture. I really recommend that you use the moisture trap at the air brush end in conjunction with the filter at the compressor side (which also doubles for pressure control by the looks of it).

Title: Airbrush purchasing for Newbs
Post by: Kjasi on June 26, 2011, 08:46:39 AM
So, I'm looking to purchase my first airbrush soon, and I want a good idea of names, brands, and items that I'll need to get in order to have it work well.

At the moment, I'm looking at getting these items (http://www.amazon.com/wishlist/1SV6YBN5ZWQV5/ref=cm_sw_r_tw_ws_bdMbob0EDGBPA) but I need to know if these are good items to get or if you think I should go with something else. I also have absolutely no idea of airbrush Brand-names, other than Iwata, but I'm looking to keep this first airbrush on the cheap side. (I'll get another, better airbrush after I've gotten some experience with it, and have more money.)

If you can think of something I should have on that list, please mention it, and include the reason WHY I need it. That way, I'll understand it's importance.

Finally, please note that I'm in the USA, and I would prefer to not buy these items from overseas. Thanks! ^_^

Hi guys,

Have been looking at getting an airbrush and a compressor. Am currently in Japan, therefore Tamiya brand seems to be quite popular here.
Here are 2 sets which have caught my eye. 
 
Set 1:
http://www.hlj.com/product/TAM74515
http://www.hlj.com/product/TAM74519

Set 2:
http://www.hlj.com/product/TAM74520

Since I have no idea as to what I should be getting or what I should be looking out for, comments or any thoughts on the items above are very much appreciated.
Title: Re: Air Brush and Compressor Discussion Thread

Title: Re: Air Brush and Compressor Discussion Thread
Post by: potchip on June 28, 2011, 06:59:46 PM
It's good enough. The pricier ABs are really for fine work, and gundams don't really need that much fine lines. You'll also need plenty of masking tape...
Title: Re: Air Brush and Compressor Discussion Thread
Post by: Garret Masterson on June 28, 2011, 09:14:28 PM
@Kjasi & iceman90

Choose the set 2 link the Tamiya basic Sprayworks.  It'll give you all you need for airbrushing model kits.  That's what I've been using for more than 2 years now and it never let me down.  Just a word of advice: never use it for more than 30 minutes.  It'll destroy the gears from overheating.  I've read people abusing it spraying for over an hour and the mechanisms just gave out.  Just let it rest for 30 minutes after you use it and you're good to go again.

If ever you want to upgrade your airbrush.  Just buy a tamiya HG Spraywork airbrush.  It'll give better control than the one provided with the basic spraywork (which I still use for priming my kits).

Title: Re: Air Brush and Compressor Discussion Thread
Post by: iceman90 on June 28, 2011, 10:19:53 PM
Thanks for your reply garret. I've decided to go for the pricier set as there was a discount of up to 40% on amazon japan. While I do want to save a little, the place I'm staying at is a paper thin apartment and I'm worried about the noise output by the cheaper compressor. Have gotten the better compressor and a HG spraywork airbrush. :) Might get a basic one for the priming work but I'll play around with my set first.
Title: Re: Air Brush and Compressor Discussion Thread
Post by: Kjasi on June 29, 2011, 10:24:31 AM
@Garret: I took a look at that system, and frankly, I'm not that thrilled about it. It looks kinda cheaply made, requires the separate purchase of a battery, (No AC power option? Really?) and it overheats after half-an-hour?

Thank you for your suggestion, but I think I'll go with my current choice (http://www.amazon.com/wishlist/1SV6YBN5ZWQV5/ref=cm_sw_r_tw_ws_bdMbob0EDGBPA) instead. If nothing else, I can easily upgrade each part of it when I get the money for a better system. Plus I can use it on more than just Gunpla.

I DID look at the US eBay recently, and I noticed "nail airbrushes" for like $5 USD a pop, plus S&H. Anyone know if "nail airbrushes" would be a good, cheap airbrush? (Almost disposable airbrush...) They look like they're double-action, gravity fed...
Title: Re: Air Brush and Compressor Discussion Thread
Post by: GacktC on July 04, 2011, 06:42:22 PM
I bought my Airbrush from school with a student discount years ago, it was like $125 for my Iwata HP-C. Parts are super expensive in these days, for a freaking needle, it costs almost $20, and that tiny tip underneath the nozzle already $35!!!WTF?? But my airbrush is still survive after 15 years (maybe I only use it once a year the most?).
The compressor that I have is a little Testors, it is very quiet with enough power (20 PSI if I am not mistaken), and I paid $95 for it 6 years ago.

@kjasi. Those ebay cheapies will do ok for messing around and learning on. Don't expect much of them and you wont be dissapointed. I have a couple and just use for spraying undercoats and clears. I wish I had bought some of them before I spent $100 + on an air brush because some of your expensive lessons can be learnt on the cheap throw away ones.

So it would be wise to get a few $5 airbrushes for learning and probably priming. That's about what I was thinking. I didn't think they'd be "OMG! Teh gratest evar!" kinda airbrushs, but a good learning/primer brush. I'll probably grab a few when I order my system from Amazon.
Title: Re: Air Brush and Compressor Discussion Thread
Post by: GacktC on July 04, 2011, 07:40:17 PM
I suggest just to get a decent one than keep on buying those $5 airbrushes. A decent one can last with proper caring and cleaning, just make sure don't bend the needle :)

Thanks guys for your earlier replies.With your help I ended up with this setup.
Arrived from hobbytools.au on Friday,haven't stopped reeking of thinners since  ;D

Artlogic compressor,sparmax DH 103 AB,3m braided line and in line moisture trap as suggested by GOZ *thanks*
First real session was tonight,compressor got a little hot but certainly didn't affect the result.
Really happy and was delivered to Brisbane for just on $300.

Can anyone help with the thinners/clear ratio for Tamiya clear with same brand acrylic thinners??

Also I purchased some Tamiya flat base in a bottle.Do you add a small amount to the clear to attain a clear,flat finish?

Title: Re: Air Brush and Compressor Discussion Thread
Post by: Hoardz01 on July 05, 2011, 05:47:24 AM
@Alphabeta. I have the exact same setup, minus the tank unfortunately. Does run hot. I'd suggest with the tamiya clear start with 50/50 and adjust as necessary. Others would be more in tune with how to use that product. I just bought some flat base too, so very interested to hear how you go with that. I have read that you can mix it with future to make a matt. The ratios are on fitchenfoos site.
Title: Re: Air Brush and Compressor Discussion Thread
Post by: alphabeta on July 05, 2011, 08:18:47 AM
Thanks Hoardz,will start with a 1:1 ratio.Just wanted to confirm before trying,would hate to destroy a kit
at the clearcoat stage  :-X
Went for a look for some Future polish for no luck.Local various supermarkets and hardware stores
have no stock...looks like I am a lil late for that one.
Title: Re: Air Brush and Compressor Discussion Thread
Post by: Sonar on July 05, 2011, 10:41:11 AM
That's a good setup Alphabeta. Mine runs hot too, and I don't have a tank. You just have to give it a break between colours. Your speed and technique will improve/come back pretty quickly with a bit of practice, and this will mean shorter run times between breaks for your comp. Last thing you want it to do is seize. I wonder if running them in a bit woould help? Surely it would?

Post by: alphabeta on July 05, 2011, 10:52:41 AM
It is my first ever experience with an airbrush mate,gave it a quick go Friday pre shading some zaku parts.
Spent yesterday driving around buying paint and spent most of last night playing with the paint flow control
settings and starting spraying the base coat last night.
Spent some time mixing the paint/thinner ratio and generally just getting to know how to use the thing!

The compressor had a fan blowing over it the whole time,it didn't get uncomfortably hot.And you make a great point that I won't "lean"
on the compressor as much as skills grow.

Oh and it is really quiet too,nice touch!
Title: Re: Air Brush and Compressor Discussion Thread
Post by: Hemish on July 05, 2011, 06:59:29 PM
Noice, looks very similar to mine.
In regards to the tamiya acrylics, ppl say a consistency like milk, I find 1:1 good sometimes a bit more thinner, depends on the colours that I'm using too.

As for the Tamiya flat base, I just mix that with thinner and spray on as my flat coat

We really need to organise that day together :)

Look forward to it H  8) Thanks for the replies,how to use the flat base had me..

Cheers Hoardz,best hobby item I have purchased.
So many things I have wanted to try with AB that just are not possible with cans.
But in awe of how easy you guys with the know how make it look.Appreciate even more now the
finishes on some works I have seen here.

Title: Re: Air Brush and Compressor Discussion Thread
Post by: TheGhostofZeon on July 05, 2011, 08:48:52 PM
Consistency of milk is a good starting point when thinning but I generally start at 70% paint to 30% Tamiya thinner as a starting point and that works well.

General purpose thinners sometimes get mixed at 1:1 when using acrylics.
Title: Re: Air Brush and Compressor Discussion Thread
Post by: KaiK on July 06, 2011, 03:12:32 PM
Keep in mind mixtures are one component to airbrushing, another is pressure which doesn't seem to be discussed as much. I use a 70% thinner to 30% paint ration for most acrylics and lacquer, however I sometimes spray paint straight from the pot with no thinners to get a rough texture or as a primer/base coat. The different mixtures need different pressures to work properly. Thicker paint generally needs higher pressures to spray and thinner works better with lower pressures. 18 psi is my main working pressure which I use a 70/30 mix, this gives me a bit of room to raise or lower the pressure depending on the consistency of the mixture, also at this pressure my moisture trap will always function properly. At 25+ psi I can spray all the thicker mixtures however over time the moisture trap will become saturated and water can start to spit out with the air, this is where an inline filter comes in handy.

A data base of paint type/paint mixtures + pressures would come in handy for everyone as a reference point.

Okay, slightly off topic, but related: What kind of thinner should I use with my acrylic paints for airbrushing? I've heard lacquer thinner works just-as-well-as, if not better-than, acrylic thinner... (I'm looking at Tamiya brand thinners with Tamiya Acrylic paints.)

Isopropyl Alcohol works well and can be readily found in hardware stores. General Purpose thinners work OK too but 9 times out of 10, I stick with Tamiya Acrylic Thinner (which is similar to Isopropyl anyways).

Oww... I just airbrushed for the first time. Wasn't a model kit though. Had to airbrush some foam ears for a parade float my boss in entering. It was quite the trial-by-fire! I was the only one there, had loads of problems with the paint clogging the airbrush, (took me a while, and several cleanings to figure out that THAT was the problem) and now my back hurts.

Once I figured out the problem it was much better. The airbrush is a Paasche VL. Anyone else use one of these? It's a bottom-loading dual-action airbrush, but the dual-action doesn't work. It might of been reassembled wrong before it was stored, and I have no idea as to how to fix it.

But as a whole, it was a great experience. Definitely going to get myself a gravity-fed airbrush.
Title: Re: Air Brush and Compressor Discussion Thread
Post by: QuangVuong on July 14, 2011, 08:41:42 PM
If its dual action you can control the amount of air and paint which comes out. So you puch down for air, then pull back for paint. When you pull back the needle should move back, aloowing paint to exit. If your need is bent or not true anymore, then youll need another one.

Personally I like gravity feeds better.
Title: Re: Air Brush and Compressor Discussion Thread
Post by: Kjasi on July 15, 2011, 05:35:52 AM
I press down, I get paint & air. I pull back, and I get paint & air. The forwards/backwards placement doesn't change how much paint comes out, even though I know it's supposed to. And the pressing down is almost binary... (Either that, or I'm pressing too hard...)

So, I think it's more of the pullback mechanism isn't working because it isn't assembled correctly. I'll check the instructions and see if I can fix it.
Title: Re: Air Brush and Compressor Discussion Thread
Post by: QuangVuong on July 15, 2011, 07:44:38 AM
Sounds like your needle has a problem. Check out the tip of the needle if it  moves while pulling back.

word of warning from personal experience, normally lacquer thinner thins everything, but DO NOT use it on games workshop paints...
i actually screwed an AB like that, as in beyond repair, i mean if you cant get it out with automotive lacquer thinner or pure ammonia, nothing is gonna save that brush now...

Laquer thinners & ammonia are rank amatuers at dissolving stuff. If you want your airbrush cleaned get some serious solvent like toluene, MEK or xylene. Word of warning though; make sure you remove ALL rubber, leather, cork or any other type of seals before you use those solvents otherwise you'll never get them out after.

Title: Re: Air Brush and Compressor Discussion Thread
Post by: jnhchan on July 16, 2011, 01:49:22 AM
just use model use acrylic thinner.  If you want to save money, use water to clean your AB during the painting process and use thinner to clean your AB when you finish all the painting.  I found out that the cleaning process waste most of the thinner.  Thinning the
paint is only about 30% of my usage.  Rest of 70% is cleaning.

I appear to have a problem with my airbrush. I have a gravity fed dual action brush from super cheap auto and after cleaning it once ive found that after pushing the trigger down it gets a little bit stuck.

Remove the hose attachment, 'o' ring and plug, check for moisture and/or paint. Do not use any lubricant on the 'o' ring or plug since it can cause clogging to occur within the airbrush.

Well, good news! After completely disassembling then reassembling my dad's airbrush, it's working the way it's suppose to now! I don't think it was assembled correctly after it was used last.

I just need to align the needle a bit more, because it's still spraying a bit of paint when I just hold down for air. But other than that, it's working like a charm!

So, after working with it for a bit, it's obvious that getting paint to the consistency of milk is my current issue, (Mine ends up too watery) so I'm going to work on that. But I forget... What do I want to thin Mr. Surfacer with? I remember it's a 1:1 ratio, but I can't remember if it's with some kind of thinner or if it's with water...

I ordered some airbrush medium from Amazon to give it a try. Supposedly this stuff not only thins but helps the paint stick better as well. Here is a link:

http://www.amazon.com/gp/product/B001US2NQA

This is the product description:

A pre-filtered ready-to-use medium that easily thins any acrylic watercolor or gouache to the right consistency for spray application. An excellent choice for color washes and watercolor techniques when used with acrylic colors. Mixes well with other mediums to adjust the body and handling properties. Maintains integrity of acrylics even at high dilutions and decreases airbrush clogging and paint buildup. Use with Liquitex Soft Body Color for best results.

Sounds like it's used for airbrush art, ie painting on paper/cloth...Not sure it would help paint stick to smooth plastic surface..

Ideally thinner you use for plastic kits should attack the plastic a little so paint stick - the same reason plastic putties has some solvents..

For Mr Surfacer 500 and 1000 I generally use a 50/50 paint/thinner mix @ 25psi, for Mr Surfacer 1200 I use 70/30 mix and add a few drops of paint retarder @ 18-20psi. See how it works out for you.

In regards to your airbrush check the nozzle for splitting and warping, it might be part of the reason for the paint flow.

Well after reading through this thread and much consideration I decided I needed an airbrush set-up as hand painting blows!

I wanted the air compressor that was recommended at the start of this thread and www.hobbytools.com.au (http://www.hobbytools.com.au) had the best price around. But I was unsure of what airbrush to get so I emailed them and the owner, Gary, got back to me quite quickly. After a lot of back and forth he had organised a custom package for me!

But then today before I was about to order he emailed me and said he had new packages thanks to price drops from suppliers!!!

Ended up going for http://www.hobbytools.com.au/prod268.htm (http://www.hobbytools.com.au/prod268.htm) which seemed the best bang for buck for a complete AB noob!

Will get an in-line moisture filter and another cheap AB unit later but this should get me started! If anyone is umming and ahhing about starting out with AB then you should most definitely consider contacting Gary as he seems open to organising package options to suit your needs and budget.

@ Kjasi. Lets hope that my talon is as good as the paasche you got to use.

@Rogg. Looks like a winner setup, I have the same compressor/AB minus the tank. Works a treat, wish I had the tank! The sparmax is a good AB, just make sure you keep it clean and be careful if you remove/insert the nozzle. Mine cracked because I used too much force tightening it and now I need to spend $25 on a new nozzle. From what I understand all nozzles of this design have this problem and is a typical beginners mistake.
Title: Re: Air Brush and Compressor Discussion Thread
Post by: Noless on July 19, 2011, 11:30:44 PM
i have the DH103, its a lovely brush and the 0.3mm nozzel is a good size for general purpose, i much prefer the trigger system on the sparmax than the delta (on the sparmax the "trigger" is not directly linked to the pin that presses the air valve, so pulling it apart is a bit easier) and i can attest to good build quality, as long as you clean it properly it should serve you well

I was totally amazed today to find that the seller of this airbrush refunded $15.00 of my shipping because he found a cheaper way of getting it over here. That makes it $80 shipped from the US, can't even imagine what you would pay retail. Hobby tools, as great as they are, have it listed for about $170 + Shipping.

Well, Ive used those Chinese $20 airburshes from eBay, and they work well for their price.

For an aircompressor, well that may be tricky to find cheap. Either you spend about $120 on a new airbrush compressor(eBay) or ~$100 on one of those large ones(from Bunnings, etc). So youll be spending about $150 on a whole AB system that works well for a beginner.

Im gonna get another AB and compressor soon.

That one from Amazon is the one I have. The airbrush is a Master brand model G22. It is actually pretty good for the price. I showed it to the guy that runs the local hobby shop and he was very surprised at the quality for the price. My only complaint is that the brush does not have built in control for spray cone size; if you get the Major repair kit ($20 normally but on sale right now for about $13) from them you can get that though. I have mine ordered and should have the adjuster in a few days.

TCP Global seems to be the only ones I can  find that sell the Master brand so I think it may be their in house brand. That being said their customer service is also top notch. When I ordered from TCP Global directly and they messed up and sent me an incorrect item, they were super helpful on the phone and shipped me the correct item that day.

As far as the G22 itself, I have only done one kit with it so fat, an HG Shinanju (catapult post inc ;-p)and I very much like the airbrush so far. I'll be painting my Epyon with it in the next few weeks, once I can get time to finish clipping and sanding the parts. After that, I think I'll have a better feel for how well it works.

So, being new to airbrushing, if I experience paint building up on my needle at the tip could that be because the paint is not thinned enough? It only seems to happen with one paint I was using consistently.
Title: Re: Air Brush and Compressor Discussion Thread
Post by: QuangVuong on July 29, 2011, 06:56:56 AM
Paint will always find its way to the tip, but not much. If its building up as a blob, then yeah your paint is too thick. Or the other thing is your air pressure may be too low for the viscosity of the paint.
Title: Re: Air Brush and Compressor Discussion Thread
Post by: Dakaramor on July 29, 2011, 07:21:51 AM

Title: Re: Air Brush and Compressor Discussion Thread
Post by: QuangVuong on July 29, 2011, 07:24:26 AM
Air pressure is a big thing when airbrushing. Try out different pressures and viscosities of paint. You can get a clean smooth look, or you could go for a slight matt finish. Experiment til you find nice settings.
Title: Re: Air Brush and Compressor Discussion Thread
Post by: Dakaramor on July 29, 2011, 08:58:22 AM
Assuming the paint is correctly thinned does a higher pressure get a smoother paint and a lower pressure go for a more matte finish?
Title: Re: Air Brush and Compressor Discussion Thread

I'm thinking of getting a full set of airbrush and compressor in near future. And I'd like to get suggestions from the members of this forum. What brand should I get? How do you judge an airbrush is a good one or bad one? How often do you guys do maintenance on your compressor?

Currently I have limited budget (around AUD 300 for airbrush, compressor and a set of paints).

Thanks.
Title: Re: Air Brush and Compressor Discussion Thread
Post by: potchip on August 24, 2011, 04:51:30 PM
You don't need expensive items starting up. With your budget you might as well go for the cheaper taiwan brands like sparmax for the brush and a reasonable compressor to start up. Sparmax has spares which makes it easier to maintain than a no-brand where you have to buy a new one if your nozzel/needle etc gets damaged. For compressor I got the 1/6 horse power one (with a moisture trap though) like many above recently for ~70. However I feel it is underpowered - the pump's always working anyway so the power-off feature is pointless. If you can get a 1/4 or 1/3 hp one do get. Never had to maintain my 1/4 hp compressor for 5 years

I would suggest invest in two airbrushes one with 0.3-0.4 tip and one with smaller tip for detail work.
Title: Re: Air Brush and Compressor Discussion Thread
Post by: QuangVuong on August 24, 2011, 05:11:29 PM
$300 aint limited. Its quite a bit. Well I recently bought an aircompressor for about $70. It is bidding so prices can go up to $100. Link is up above.

As for the airbrush youll prob want to spend the rest on it. YOu could get a $20 off ebay or bigger brands like Paasche or Badger which go up to the high hundreds. YOull have to judge the AB yourself.YOu may like siphon feed ABs while other may like gravity feed ABs more. Its an opinionated thing.

And for paint they are about $4 a pot from hobby brands, or art stores have larger tubs for about the same price.

Randmness, do you have any idea how to work the pressure tap. Mines kinda weird. To turn off you unscrew it about halfway, and thigtening it makes it go up to 40 PSI. How do you set yours accurately?

Quang, I am laughing terribly hard at the moment as your setup looks EXACTLY like mine.. minus the filter and a different hose!

The knobs are really weird yes, I tend to keep the AB running as I adjust the pressure at the start so I can gauge how much to turn. Haven't been able to really test it out but damn the knobs are sensitive!
Just one other note, the pressure release valve on mine is a bit touchy sometimes.
Title: Re: Air Brush and Compressor Discussion Thread
Post by: QuangVuong on September 13, 2011, 07:32:49 PM
Touchy as in...? I only use that once Im done with airbrushing.

Well Im thinking about getting adaptors, so I can put the airfilter in line from the tank to the regulator. Saves me $10 from buying another one.

Oh and for you guys who prime using an AB, Which size nozzles do you use? 0.8mm? Or would a spray gun(automotive) work better. Im just wanting a wide enough coverage over the pieces.

And has anyone used Vallejo waterbased primers?

Touchy as in if you put any sort of force on the release ring it'll release.

I was wondering what beginner/basic/average AB you just would reco me to get since my cheap delta one broke on the 2nd use today.

How? I cannot imagine airbrush 'break' other than say nozzle is broken off. Everything else either will not break or you can replace. You should ask for a replacement if its due to some defect or source spares..and I certainly wouldn't even consider delta ab as the cheapest..

Real cheap aircompressor and airbrush set from Target. Its only $129 . Looks like a dual action siphon feed AB with a compressor and hose. For its price it is quite cheap. $129 on sale tomorrow(6.10.11) or $150 afterwards.

Yes it may be for tanning, but you can use it for painting too! Though dont know about the compressor. May have to look at it in a store tmw.

So, after failing on my MG Freedom wings with hand paint, I'm really considering getting an airbrush now. The only reason I haven't gone for an airbrush is because I can't find anywhere to do it. Which is why I'm here posting this, maybe some of you can give me some advice. I don't have a garage or a back shed where I can set up an airbrushing station. Most of my work is done in my room.. Is there any safe way to airbrush in the house?

I've had a look at spray booths, but it seems like the exhaust needs some way to exit the house? My windows are lined with mesh cloth so there's no way the spray booth's tube (excuse my poor wording!) can get outside.

I'm at a complete loss and would appreciate any suggestions right now!
Title: Re: Air Brush and Compressor Discussion Thread
Post by: QuangVuong on February 20, 2012, 07:31:24 PM
I know this isnt preferred, but I actually do my airbrushing outdoors, along with drying outdoors. That is in the open, not under any cover. I havent had any issues with dirt or dust wrecking the paint job. But I guess this is just me.

Hey, i'm looking at purchasing a starter airbrush and compressor, and i came across this kit on ebay. What do you guys reckon?

It seems very cheap, even considering the exchange rate, and that people are going to bid the price up. But is it going to be rubbish? Yay or nay?
Title: Re: Air Brush and Compressor Discussion Thread
Post by: Hemish on March 07, 2012, 11:44:02 PM
It probably wont last long, but be a good one to test the waters on
Title: Re: Air Brush and Compressor Discussion Thread
Post by: potchip on March 08, 2012, 08:24:31 AM
It's compact and possibly quiet, suit those apartment types. The shipping is quite expensive, and given it's overseas, the 12 month warranty is useless. From past auction results, it will go up to between 60-90 AUD + shipping.

I don't see a HP rating specified everywhere - the higher the better. My new compressor is the cheapo one you can get from ebay.au for ~70 delivered. Even though it has a tiny tank, It really sucks when it takes 20 seconds for the thing to charge up to reasonable pressure and there's just a feeling you can't go long on max pressure at all. Luckily painting gundams typically doesn't need higher than 30 psi but sometimes you want high flow for gloss/big coverage.
Title: Re: Air Brush and Compressor Discussion Thread
Post by: Skin_the_Sun on March 08, 2012, 04:22:11 PM
Ok, thanks for the advice, guys, probably going to avoid it then. Can anyone recommend a good starter kit; ie. airbrush, compressor, and everything else i'd need (hoses, moisture trap etc)? It doesn't matter if i have to purchase airbrush/compressor separately, as long as i can get everything i'd need for a reasonable price, and reasonable quality. I suppose that is asking a lot..... ;)

Title: Re: Air Brush and Compressor Discussion Thread
Post by: Skin_the_Sun on March 08, 2012, 09:14:44 PM
I have read quite a few of the pages yes, but everyone seems to have different and specific needs. I do not have that much money to spend, i should have mentioned that I am hoping to get an airbrush and compressor for about $200 (less if possible), perhaps that is an unrealistic expectation for something that won't break though. ;)
I also have no previous experience so something relatively easy to use would be helpful as well. I've looked at a lot of the suggestions in the thread, but most of them seem a little over my budget, which is, well, budget-price lol.
Someone suggested Runway 13, they seem really good, their prices seem really reasonable if their products are as good as they seem, but again, it might be a bit more than i have to spend.

Thanks Hemish, that seems like a really good deal, right around my price range too. If i decide to upgrade the airbrush at a later date, I can always keep the comp so that seems like a good option with long term in mind as well, thanks mate! :)

Title: Re: Air Brush and Compressor Discussion Thread
Post by: QuangVuong on March 29, 2012, 05:42:32 AM
The airbrush is would be good, but the compressor doent seem like itll last. Id spend a little more to se a decent compressor. Try Princess Trade on ebay or their website. Aussie seller with pretty cheap and good compressors.
Title: Re: Air Brush and Compressor Discussion Thread
Post by: thegunny on March 29, 2012, 07:17:29 AM
Just remember, you get what you pay for. Top line airbrushes and compressors are expensive for a reason  ;)

Your choice would be good to learn on but don't expect it last you for very long, especially the so called compressor. Make sure you spring for a water trap as that compressor will make a lot of moisture if it's been running for a while.
Title: Re: Air Brush and Compressor Discussion Thread
Post by: randmness on March 29, 2012, 05:45:45 PM
I concur with thegunny and Quang.. that compressor looks too much like a toy. No pressure adjustment, no tank, *needs to be cooled every 30 minutes...*
The airbrush on the other hand seems ok but for the money, you'd rather buy each part separatly. The princesstrade compressors (at least the black case one with a tank which is what I run) is a nice starting point if you manage to run into a non-compete on on Ebay from them.

Title: Re: Air Brush and Compressor Discussion Thread
Post by: TheGhostofZeon on March 31, 2012, 09:38:51 PM
If you are getting a water trap, make sure you get one at the air brush end not the compressot end. A lot of moisture occurs in the hose to the brush so putting one before it will not work efficiently.
Title: Re: Air Brush and Compressor Discussion Thread
Post by: Ethan on March 31, 2012, 10:22:57 PM
@Goz, I'm currently using a Sparmax moisture trap on the compressor end and I find that it works fine. Does it really make a big difference if I have one on the airbrush instead of having on on the compressor end??
Title: Re: Air Brush and Compressor Discussion Thread
Post by: TheGhostofZeon on April 01, 2012, 11:33:34 AM
A large amount of moisture can occur in the hose if the room you are in is cooler than the compressor is. When the hot air meets the cooler hose, moisture forms quickly. Having a trap at the compressor is ok but doesn't remove moisture that occurs after it.

I find it best to have the trap at the end of the air rather than half way, that way all of the moisture is removed before the air brush.
Title: Re: Air Brush and Compressor Discussion Thread
Post by: randmness on April 01, 2012, 05:15:56 PM
Just broke my airbrush >.<

Was disassembling it for the first time, putting it back together and the thread of the nozzle (the tiny bit they give you a spanner to get off) broke off while I was tightening it...

Lesson learnt: don't try and over tighten the nozzle.

Good thing is it only cost me $12 but the whole thing is essentially useless bar the needle, but even that may be useless as the nozzle's dead.
Title: Re: Air Brush and Compressor Discussion Thread
Post by: Skin_the_Sun on April 05, 2012, 06:44:24 PM
Yay! I just won that compressor on ebay for $51 plus $23 shipping. So now i need an airbrush. I was thinking of this kit as it supposedly has everything a beginner needs, although i'm not sure how good it is for modelling as opposed to other airbrushing uses.

http://www.hobbyserv.com.au/index.php?act=viewProd&productId=31

 I'm not looking for anything too flash to start with, regardless, what do you guys think?
Title: Re: Air Brush and Compressor Discussion Thread
Post by: Ethan on April 05, 2012, 07:04:50 PM
I think that the airbrush is a great starting point, nothing too complicated. But if you want something a bit fancier and higher quality, I think you should try something from Badger or as GoZ once suggested to me, something from http://runway13.com/store/index.php?main_page=index&cPath=1_17
Title: Re: Air Brush and Compressor Discussion Thread
Post by: Skin_the_Sun on April 06, 2012, 05:23:16 PM
Those look really good, i've checked out Runway 13 before and people seem to agree that their products are of the highest quality. Just probably a bit more than i wanted to spend at the moment though, although if i want to upgrade in the future, i think one of their airbrushes would be an excellent choice.
Title: Re: Air Brush and Compressor Discussion Thread
Post by: TheGhostofZeon on April 06, 2012, 06:29:09 PM
If you are worried about price, grab a cheap one from eBay. It's best to learn on a cheap one rather than breaking an expensive one.

Runway 13 is the go though. Quality of the more expensive brands for a fraction of the price.

EDIT : There are $20 ones on Princess Trade at the moment. Beware - you get what you pay for....
Title: Re: Air Brush and Compressor Discussion Thread
Post by: TheGhostofZeon on April 25, 2012, 11:23:29 AM
Sooooo, since my Sparmax compressor died last week (as I posted in the Recent Purchases topic) I 'lashed' out and grabbed a compressor from Princess Trade. It's been a few days since I started using it and I thought I'd post up some pics of the unit and my thoughts for those of you who are looking for a compressor.

(http://www.ghostofzeon.com/various/new_compressor_small_02.jpg)

I paid $130 odd including postage for the one I got. Princess Trade have a few different units for various prices and this one is the middle of the range and has a tank below the compressor (other models are compressor only and with tank and cover).

First and only issue I have had so far is that the hose adaptor is 1/8" and the end of my air brush hose (like most) is 1/4". Simple fix, I removed the adaptor from the old Sparmax and got a 1/8" to 1/8" female adaptor to join both together.

The unit has a pressure gauge and adjustment knob before the hose which is easily adjusted. Most paint I use has been air brushed at between 25-30 PSI and everything sprays on neatly and evenly. The unit continues to operate until the pressure reaches it maximum and then the compressor turns off.

Having the extra tank to hold a reserve of pressurised air helps keep the PSI levels between the range I need without dipping too low. Once the pressure starts to fall, the compressor turns back on and fills the tank once again, keeping pressure levels even.

The unit also features a thermal cut off so if it runs for too long and the unit gets scolding hot, it will turn itself off before any damage is done to it.

Compared to the old Sparmax, this unit is quite large but the compressor itself is a similar size :

(http://www.ghostofzeon.com/various/new_compressor_small_01.jpg)

So far it has been working a dream and I am quite happy with it. If I find any issues in the future, I'll post an update but at the moment, it all works great!
Title: Re: Air Brush and Compressor Discussion Thread
Post by: Sonar on April 25, 2012, 05:25:55 PM

Title: Re: Air Brush and Compressor Discussion Thread
Post by: TheGhostofZeon on April 25, 2012, 06:23:19 PM
There's a bit of noise but not as bad as the old Sparmax. I'd imagine that the noise levels are on par for an air compressor.

Hi Guys,

Iím new, and was hoping someone can give me some insight into this.

Iím looking for airbrush and compressor

I know what I should get, from reading online, but Iím still uncertainty on what brand to get, any advice would be great.
 Will it make a big difference getting a cheaper brand that has all the specification?

My Budget is around $300 but if possible I would like to spend lesser.
However I want value for money, I hate to find out later that I should of spend a bit more money to have a good airbrush and compressor.

At the moment

I have search around and saw this Dynamic Power brand from
http://www.princess-trade.com.au/cart/dynamic-power-1-6hp-air-brush-compressor-with-tank.html $79.95 or http://www.princess-trade.com.au/cart/dynamic-power-1-6hp-air-brush-compressor-with-tank-metal-case.html $89.95
http://www.princess-trade.com.au/cart/dynamic-power-dual-action-air-brush-with-micro-air-control.html# $29.95

Or

Spend a bit more and get Compressor and Airbrush

Post by: QuangVuong on August 10, 2012, 07:17:05 PM
THat first Dynamic power one is just like the  one from HobbyTools.

Ive got the second Dynamic Power compressor there. Basically all three have the same compressor. My one just has a smaller tank, but it allows for 2 airbrushes. And it does not have a air/water filter.

As for airbrushes, I just use cheapo $15 ones off eBay. They are dual action gravity feeds, and still work as they should for over a year now. Although, that Dynamic Power one looks like my very first AB. Its better than my current one now, so go for it!

Hi Everyone,

First post and im asking for help :(

So Currently im just toying with the High grade gundams, learning how to build them, what glue to use and what not to use. I finished my first few and i really want to paint them and make them cool, however hand painting them hasn't really given me a good result. So after chatting with some people they suggested that i use a airbrush. So being new to this google explained a fair bit,and after reading through this post i just became more confused. After all of this i was still unsure what would work for me and what i should buy.

So i ask what is the different between these three "packs" and do they offer everything i need to start painting my gundams :)

http://www.hobbytools.com.au/airbrush-compressor-kit-2a-super-quiet/ (http://www.hobbytools.com.au/airbrush-compressor-kit-2a-super-quiet/)
http://www.hobbytools.com.au/airbrush-compressor-kit-2/ (http://www.hobbytools.com.au/airbrush-compressor-kit-2/)
http://www.hobbytools.com.au/airbrush-compressor-kit-4-super-quiet/ (http://www.hobbytools.com.au/airbrush-compressor-kit-4-super-quiet/)

All three fall into my acceptable $$ limit so any are acceptable, as long as it can provide a nice smooth spray. Also do i need any sort of cleaning kit as well ?

I know this seems very noobish, however there isnt anyone in my area that i can ask for guidance and some of the local stores just want to sell there stuff without really "helping".

Any and all assistance is greatly appreciated.

Thank you
Sol
Title: Re: Air Brush and Compressor Discussion Thread
Post by: Ethan on November 14, 2012, 04:33:44 PM
Okay, so the differences are the airbrush and compressor provided. Personally, I don't see why you wouldn't go for the 2A since it gives you a compressor with a tank as well as a Sparmax DH-103 (heard some pretty positive things about this) but if you want to go with a more 'reliable' airbrush brand then kit #4 with the Badger would be the way to go. Also, while choosing, you might want to take into account that kit #4's airbrush is siphon feed and kit #2 and #2a are gravity feed.

Cleaning up set wise, all you need is an empty bottle to spray your thinner into (make sure this is solvent proof!!) and a pipe cleaner. If you want to go fancier, Sparmax or Master make some specially designed spray jar thingy so then you don't have to breathe in the mists of thinner.
Title: Re: Air Brush and Compressor Discussion Thread
Post by: QuangVuong on November 14, 2012, 09:33:12 PM
You can save so much more if you purchase the compressor from Princess Trade. Links are a couple posts up.

Then youve got a lot to spend on a good airbrush, or you can buy multiple cheap airbrushes. So far, cheap airbrushes have not been any bad. Look at my works, they arent all that bad.

Hi Ethan, Thanks for your reply. qick question about this line, Is siphon better then gravity feed ?
while choosing, you might want to take into account that kit #4's airbrush is siphon feed and kit #2 and #2a are gravity feed.

Hi Quangvong, thanks for your reply,
in not over fussed about were i get it, aslong as it comes in a kit form, so to speak.. i don't want my inexperience to buy something that wont fit or work..If they have kits with everything then booya!..
You can save so much more if you purchase the compressor from Princess Trade. Links are a couple posts up.

Then youve got a lot to spend on a good airbrush, or you can buy multiple cheap airbrushes. So far, cheap airbrushes have not been any bad. Look at my works, they arent all that bad.

Also i was told i do need a water capture device on it >_< not sure why. im assuming mosture gets into the paint somehow ?.

Anyways.. thank you for the replys, ill have another hunt around today and see what i can come up with.

Cheers
Sol

...coz otherwise you will see the paint spluttered all over your piece ruining what ever you were doing. Fixing would be wash away the painting and start all over again with that piece...

^ Water trap is a must need unless you occasionally want water sprayed all over your piece at the worst moment. As for siphon and gravity, each has its own advantages. Most people go with the gravity feed but it's really up to your own personal choice. I started off using siphon and I still am. 
Title: Re: Air Brush and Compressor Discussion Thread
Post by: KaiK on November 15, 2012, 07:36:29 PM
The key point with airbrushes is not really how the paint is feed into the airbrush but more how the paint and air mix together. The two types are internal and external mixtures.

Internal - paint is mixed directly with the airflow within the airbrush chamber (most gravity feed and some siphon feed systems)
External - paint is mixed outside the airbrush chamber with separate air and paint source positions (primarily siphon feed systems)

Siphon feed airbrushes are heavily reliant on having the right mixture and more so if it is an external mix system. The only benefit I've heard about a siphon feed system is that you can store your paint mixtures and interchange colours on the fly with little wastage, in addition external mix systems are easier to clean.

Gravity feed airbrushes are primarily internal mix systems. Having a double action airbrush will further increase the control-ability of the airbrush with independent paint and airflow control. They can be a pain to clean if there has been a bit of neglect over time but it is a good system to use.

Like most things airbrushing is easy to learn and hard to master. 

Title: Re: Air Brush and Compressor Discussion Thread
Post by: dj898 on November 16, 2012, 09:05:11 AM
one more thing.
with gravity feed you can mix the paint you are spraying on the go.
For example I start with the base colour and add the colour to alter the shade or what not and do the same at each stage which means I don't have to stop clean/change/etc.
Call me lazy ^ ^

Hi all and thank you again for helping out. Sorry for the delayed responce, works been killing me..

Ok so i have a good idea of what i need and i like the whole grav feed system.. :)

So. were should i go to buy the stuff?. are there any kits that have everything ?

im still kinda keen on the A2 set that i linked before, only because it seems to have everything that is required..

Thanks again guys, i look forward to putting my first Model up in a few weeks :)

Hi peeps! Another newbie thinking about starting airbrushing here.. combing through this thread, so far I've narrowed it down to the following items for my first airbrush setup!

Dynamic Power Spray Booth (http://www.princess-trade.com.au/cart/dynamic-power-table-top-spray-booth-with-filter-for-air-brushes.html)

Dynamic Power Compressor (http://www.princess-trade.com.au/cart/dynamic-power-1-6hp-air-brush-compressor-with-tank-metal-case.html)

Runway 13 AB-120 Airbrush (http://runway13.com/store/index.php?main_page=product_info&cPath=1_17_19&products_id=3)

Runway 13 Moisture Trap (http://runway13.com/store/index.php?main_page=product_info&cPath=1_8_22&products_id=21)

I've read a few mentions that the compressor has a 1/8" hose connector, is that still the case? If so, will I need this adapter (http://runway13.com/store/index.php?main_page=product_info&cPath=1_8_15&products_id=15) to connect the hose to the compressor?

I'm also considering priming my parts with the airbrush instead of cans, should I be looking at a bigger nozzle? The one that comes with the AB-120 is 0.3mm. Runaway 13 sell two different 0.5mm nozzles (http://runway13.com/store/index.php?main_page=index&cPath=1_7_23), I'm not sure which to get or if they will fit the airbrush I'm looking to get.

Any help would be greatly appreciated, and I'm not set on those items so if you have recommendations for any better items, let me know! Money is not too huge of an issue, but less is always better and I'm going by the assumption that something will go wrong on my first go  :D
Title: Re: Air Brush and Compressor Discussion Thread
Post by: QuangVuong on March 04, 2013, 08:48:31 PM
The hose and airbrush both use the 1/8" thread, so you will not need that adapter. If you decide to change the nozzle, then you can use a smaller needle, but thatneedle will stick out more than normal.  But you wouldnt need a bigger nozzle for priming.

NB: Ive got a spare water trap thats exactly like the one in that link. If you would like it PM me about it.

That airbrush is quite dear for a no brand one. Itll do the job, but for that price, you could get something better.

Post by: Frontl1ne on March 05, 2013, 03:24:13 PM
Thanks for the handy reply QV,

Sorry I mislabeled the airbrush company, it should be 'runway' not 'runaway' :)
They have been mentioned on a few forums (including this thread!) as being very well made airbrushes.

Thanks for the offer on the moisture trap, but since it's quite cheap anyway, I don't mind grabbing it from runway if I do get the airbrush.

I will grab the stuff tonight if I don't find any other info... can't wait!


Edit:

Received my Princess Trade Compressor and Spray Booth today. They are both a lot louder than I imagined when turned on! Far louder than my computer :) Build quality isn't the best, but they should do the job fine.

Post by: Frontl1ne on March 15, 2013, 07:03:57 PM
Sorry for double posting  ;D

I received everything today and started some basic painting... Just wondering, how do people control the pressure on the dynamic power compressors? I see the two knobs but if I try to get it around 30 psi, when I spray it'll let out a little burst of air and that's it. If I leave the knob at around 45+ psi, the compressor will continuously push out air like how I imagined it would.
 Stumped  ???
Title: Re: Air Brush and Compressor Discussion Thread
Post by: KaiK on March 16, 2013, 12:08:39 AM
If you have a dual output (2 airbrush) system you will need to close the unused valve.

There is another system where it controls the rate which the reservoir tank fills up. For this I usually set it around twice my working pressure, eg. working pressure 15psi - fill rate 30 - 40 psi.
Title: Re: Air Brush and Compressor Discussion Thread
Post by: Frontl1ne on March 16, 2013, 12:38:12 AM
Thanks for the speedy reply,

I've closed off the unused port (well, just set the valve to off). This is the compressor I have: http://www.princess-trade.com.au/cart/dynamic-power-1-6hp-air-brush-compressor-with-tank-metal-case.html#


Is it normal for the compressor's psi to rise as it lets out air? I'm finding that I set the PSI to ~20 while blowing out air, and the more I use it, the higher the pressure goes. Kinda annoying since it's goes from 20 to about 40 before the tank starts refilling.
Title: Re: Air Brush and Compressor Discussion Thread
Post by: KaiK on March 16, 2013, 02:07:11 AM
Compressors with reservoir tanks can have a spike in pressure as the tank is filled during use. To avoid any problems let the tank fill up and the compressor cut off before spraying that way you will get consistent airflow until the tank is near depletion and the compressor starts up again.  

One theory, as the compressor heats up so does the air therefore pressure increases over time. Adjust pressure accordingly.

Another theory, if there is a blockage in the airbrush or hose it can cause the gauge to show an increase in pressure. Make sure there is no moisture build up in the hose or airbrush, additionally check the airbrush for paint build up around the nozzle.
Title: Re: Air Brush and Compressor Discussion Thread
Post by: QuangVuong on March 17, 2013, 10:46:05 AM
Yeah, setting pressure on that compressor is kinda weird. I usually have both valves opne as it doesnt make a difference to me. Let air run through the airbrush, and then slowly twist the knob til you get the desired pressure. When you let go, the pressure will go back up to 55psi or whatever. This is the pressure in the tank, and not the pressure coming out.
Title: Re: Air Brush and Compressor Discussion Thread
Post by: Frontl1ne on March 18, 2013, 10:02:17 AM
Thanks for all the info guys :)

Oh yeah, for anyone buying a similar setup to mine, the airbrush hose was M5 sized and the compressor was 1/4" and also the moisture trap was 1/4" lol. Luckily the people at Runway13 included adapters to connect the airbrush to the moisture trap free of charge, so I've been using the adapter to connect the airbrush hose to the compressor (forgoing the moisture trap). Gonna have to order a m5 to 1/4" adapter online since they don't seem to sell them that small locally :(
Title: Re: Air Brush and Compressor Discussion Thread
Post by: QuangVuong on March 19, 2013, 07:52:09 PM
Eh? Aint the compressor using 1/8"? Everything should be 1/8" other than the initial orange piping from the compressor to the tank(but you dont connect anything from here).
Title: Re: Air Brush and Compressor Discussion Thread
Post by: Frontl1ne on March 19, 2013, 09:15:54 PM
My mistake, I meant 1/8" and not 1/4"  :-[

But the hose was M5. I spoke to Runway 13 and they're sending me another adapter free of charge (partially because my airbrush box arrived pretty bunged up).

It's just a Delta/Sparmax copy. I've got one and it's okay if you make sure the paint is thinned a lot due to the very small nozzle. It's not very useful for doing large areas as it's more suited to fine work & lines. A 0.3 or 0.5 nozzle is a better choice for spraying whole panels.
Title: Re: Air Brush and Compressor Discussion Thread
Post by: QuangVuong on May 08, 2013, 09:07:03 PM
Ive got one myself, and it works fine. Actually, all my ABs are from China. Its capable of spraying larger areas, but essentially itll work as a single action(loosen the locking screw and pull the needle further back).

Nothing visible on the needle to indicate any issues. I've cleaned it several times but I there're two components that go into the tip that I've never broken down. It all looks clean enough but I've got it soaking right now.
Title: Re: Air Brush and Compressor Discussion Thread
Post by: Ethan on May 13, 2013, 11:37:17 AM
I've got the same problem with my Paasche Talon and I can see that the tip of the nozzle sits closer towards one side of the air cap, hence the air comes out from an angle and sprays the paint out on an angle.
Title: Re: Air Brush and Compressor Discussion Thread
Post by: Falldog on May 13, 2013, 12:16:12 PM
Well I cleaned out this one section and I either just destroyed a seal or I somehow had a bunch of purple paint stuck in there. The weird thing is that I only used purple for a few colour tests and did plenty of other cleanings and paintings afterward for it to have weathered through. I'll put her back together tomorrow and see if that sorted things out. I'm hoping that there was just a bit of blockage causing the issue. I've been having flow issues for the past two days so it's either that or something is really messed up.

Edit - After close examination of my needle there appears to be a small crook at the very end. I wish I had a magnifying glass. God damn it. Things were going so smoothly.
Title: Re: Air Brush and Compressor Discussion Thread
Post by: Shaid on May 13, 2013, 12:36:36 PM
Yeah, the small bend would probably be the culprit. As I said, it doesn't take much. ;)

I bought a metric efftonne of spares last time I bent the needle, so I can just swap in replacements when I do dumb things.
Title: Re: Air Brush and Compressor Discussion Thread
Post by: KaiK on May 13, 2013, 04:28:29 PM
A split or warped nozzle will also cause problems with the airbrush. This can occur if too much force is used when sliding the needle into place during reassembly.

Additionally if there is a build up of paint inside the nozzle it will cause the tip of the nozzle to warp because the needle does not fit in properly in its natural position.

You can check for split and extensively warped nozzles visually, however you may often struggle to notice warped <0.35mm nozzles as is doesn't take much force to damage them.

I've encountered this problem with the Sparmax D103 (and its clones) on numerous occasions. The airbrush nozzle is a hollowed out cone and as a result the very tip of the nozzle is very weak. I have not encountered this problem with my Badger or Iwata airbrushes and from looking at the design of Paasche systems they seem even less susceptible to this problem due to their heavy duty nozzle design.

   
Title: Re: Air Brush and Compressor Discussion Thread
Post by: Falldog on May 13, 2013, 10:52:49 PM
There's always been a bit of warp over the needle itself (probably after I stabbed my hand with the damn thing, still have a mark there which may be an impromptu tattoo due to paint on the end) but it never impaired painting.

I've always put the needle in backward to prevent anything from happening to the tip.

It's a good thing I saved all the documentation so I can track down the proper part number. Hopefully they'll have some one Amazon. Luckily I got a whole bunch of stuff painted so I can detail while I wait.

Post by: Suzaku on May 14, 2013, 12:11:55 AM
I bent the hell out of my Talon needle once. I was actually able to straighten it out enough to prime and basecoat with, but not enough to do any kind of shading. It didn't result in spraying at weird angles, but it did speckle the hell out of the paint and caused some nasty backups in the airbrush. That was when I decided it would be a good idea to order some spares to have on hand. I routinely do stupid things, and it's nice to have a way to fix the airbrush when necessary :P
Title: Re: Air Brush and Compressor Discussion Thread
Post by: Falldog on May 15, 2013, 05:35:41 AM
Looks like some sort of blockage was the main culprit and it's back to spraying again! There's a bit of sputtering though (paint may not be fully thinned) but I've gone and ordered a new needle just to see if things improve. Unfortunately the local shops don't carry parts for this brush but luckily the manufacturer does on Amazon!

Title: Re: Air Brush and Compressor Discussion Thread
Post by: Ethan on May 26, 2013, 04:57:53 PM
^ For preshading, I like to add a couple of drops of paint retarder to stop the paint from drying on the needle tip. Another tip is to thin the paint down a bit more than usual (I go for around 40:60, paint to thinner) and lower the pressure a bit( just helps the paint from running since the paint is thinner). Hope this helps.
Title: Re: Air Brush and Compressor Discussion Thread
Post by: thepuddingcup11 on May 26, 2013, 06:10:37 PM
why don't you just say 2:3?
also I am having major problems, arghh.
either my paint comes out wet and thin and just slides off the piece or it just sputters and doesn't spray at all.
any ideas?
also how do you change the psi?
Title: Re: Air Brush and Compressor Discussion Thread
Post by: Ethan on May 26, 2013, 09:20:39 PM
^ Why ask the question in the first place. ;)
For your thinning problem, I used to have the same thing happening all the time. I used to thin my paint inside the airbrush, problem with this is that the 'thick' paint is still sitting at the bottom even after mixing. Also, after testing whether it's properly thinned by shooting it through your airbrush, did you pour the paint out, then clean with thinner and shoot the remaining paint out if it wasn't good?

If you don't clean it out, then when you pour your newly thinned paint into your airbrush, and then you start shooting again, the 'old' paint is still inside the airbrush and that will be sprayed out first, hence you won't see a difference in performance. By the time you spray the 'old' paint out, you might have already thinned your paint down to the point it's thinner.

Sorry for making it sound so confusing or if it sounds like gibberish.

Title: Re: Air Brush and Compressor Discussion Thread
Post by: Ethan on May 26, 2013, 09:45:59 PM
If the paint isn't 'good', pour it out, spray thinner through it. Then thin new paint, then spray it. Repeat until you get a good result. Why should you spray thinner while experimenting? Even after pouring the crappy paint out, there's still a bit left in the airbrush itself.

Post by: KaiK on May 26, 2013, 10:16:19 PM
I usually test new mixtures on a bit of card in order to make sure I get good paint flow at a desired working pressure. This also doubles up as a troubleshooting process.

1. Set up your airbrush as normal and then adjust the psi to the highest working pressure. I consider 30-35psi as high working pressure   
2. Spray the paint but limit the paint flow. Too much paint flow will cause the paint to run due to the high pressure.
3. Gradually decrease the working pressure while increasing paint flow, eventually you will be able to max out the paint flow at a good working pressure without paint running.

If there are still problems or the working pressure is too high or too low then you will need to adjust the paint:thinner ratio.

I highly recommending pre-mixing paint for airbrushing. Problems with airbrushing often stem from the mixture. Pre-mixing will give you much more accurate paint:thinner ratio and allow you to thoroughly mix the paint to ensure consistency of the mixture.

I use a cheap shop canvas as a backdrop/test pad before shooting bits, learnt the hard way about spraying with clearing old paint/thinner/water first.

Has anyone else tried shooting vallejo paint thru their ab? Ive used distilled water at the recommended dilution and it was too thin, but any less than that and the paint is too thick to spray. No way im buying their thinner in a 17ml bottle..... id go thur a bottle a day at my rate.
Title: Re: Air Brush and Compressor Discussion Thread
Post by: KaiK on May 27, 2013, 02:54:37 AM
I've done some testing and here are the results.

(http://i1215.photobucket.com/albums/cc517/Kwirkshop/Misc/Resize.jpg)

Left to right: 1:2 Mr Color Lacquer thinner, 1:1 Tamiya X20A thinner, 1:1 Water

All tests were done using a Sparmax DH103 with a 0.3mm nozzle @ 15 psi

I no longer have Vallejo thinners because I don't really use their line of paints. The Dark Sand pictured is an old vial that I've had for around 5 years which I was going to use for an M1A1 tank.

All 3 mixtures have great flow but you can clearly see that the water mixture had issues sticking to the surface. Although I sprayed the paint on card you will notice that there is very little speckling with the Tamiya thinner and water mixtures, and pretty much none with the lacquer thinners.

I have a firm belief that your problems stem from how well you mixed the paint because I was extremely thorough with my mixtures and the results show.

I hope this gives a bit of insight to using Vallejo Model Color paints.



Try troubleshooting using the steps from my previous post and make sure you mix your paint thoroughly.

Title: Re: Air Brush and Compressor Discussion Thread
Post by: KaiK on May 27, 2013, 01:23:30 PM
Some acrylics (e.g. Citadel Paints) do not respond well to lacquer thinners so always test a small amount. I used Mr Color (lacquer) thinners in the test. Mr Hobby (Acrylic) thinners does not seem to be the same as Tamiya X20A thinners so I can't recommend using them with Vallejo paints. Tamiya X20A thinners will be a good all rounder acrylic thinner to have on hand along with Tamiya Lacquer thinners which perform similarly to Mr Color thinners.

Post by: KaiK on May 27, 2013, 03:00:58 PM
Some people like to put cotton inside the moister trap (glass vial) to absorb moisture, I don't personally do this.

There should be a bleed valve at the bottom of the moister trap to control the psi. Check for something that is easy to unscrew.
Title: Re: Air Brush and Compressor Discussion Thread
Post by: thegunny on May 27, 2013, 03:01:03 PM
The white cylinder with the black bottom inside the glass should be a paper filter. The whole thing is a moisture trap but it doesn't look as if it has a regulator unless those half circles visible on the top are buttons of some sort. As that compressor doesn't have a tank you will always get some sort of problem with consistent airflow. The bit sticking down below the glass should be a drain for the moisture trap.

That's not a pressure regulator that will just let air vent out the bottom.

Since there is no regulator in series with the moisture trap then there should be a bleed off valve on the moisture trap. A bleed off valve can control the output psi.

I apologise if I failed to reiterate the point of the link, I will remember to expand further in the future and use this opportunity to correct any misconceptions.   

Summary at the bottom.

The point of the following link http://www.sparmax.com.tw/accessories_2.html#amp is so that a person can familiarise themselves with the various attachments available from Sparmax. Additional a person can identify what a 'bleed valve' is and refer back to the image of an MF8 moisture trap and note where the bleed valve is attached. Furthermore you can compare the physical design differences between a bleed valve and pressure regulator.

The following link has an image of an AC100 compressor: http://www.sparmax.com.tw/air_compressors.html

It should be noted that the AC100 compressor has a moisture trap with a bleed valve attached and no inline regulator. The specifications of the AC100 state the following:

‧Motor : 1/8 HP AC
‧Airflow : 12~16 lpm
‧Max. Pressure : 80psi
‧Weight : 3.4kgs / 7.5 lbs
‧Size : L26.5 x W14.5 x H17 cm
‧Equipped with Moisture trap / Pressure gauge
‧Pressure adjustable

The following points should be noted:

The AC100 has an airflow of 12-16 lpm. This is relatively low but is suitable for use without the need of an air tank. Due to the low flow rate I would not recommend attaching and air tank to the system unless you have enough patience to wait for the tank to fill up, additionally the compressor does not have a pressure cut off and will continue to function up to 80 psi. Unless the air tank is rated for more than 80 psi it is not safe to let the system work up to that pressure.
The last entry on the specifications is 'Pressure Adjustable'. Since there is no inline regulator the only way to adjust the output pressure is turn the bleed valve. While it's not a pressure regulator it can be used to regulate the output pressure.

Back to issues on hand, the images which have been post from other sources show an AC100 (I can only assume) with a different attachment on the moisture trap. The object looks like an adaptor rather than a bleed valve. If this is the case then I can only assume the wrong part has been attached to the moisture trap and you should seek clarification from the seller. 

The issue raised by thepuddingcup11 indicates that there may be problem with the pressure gauge (refer to http://www.sparmax.com.tw/accessories_2.html for images of pressure gauges).

i see, the psi meter goes to a hundred but i cant get it past 17? oh well.

The reading on pressure gauge of an AC100 compressor should not exceed 80 psi which is the max pressure of the compressor. If it does there may be a mechanical problem with the pressure gauge, worn or corroded springs for example. Unfortunately there is too little information to assess why the final output is only 17 psi, I can only speculate. 

Since there is no inline regulator I can only assume the bleed valve is the only control option. 17 psi is actually quite a good working pressure but if there is a problem with the gauge the output pressure might actually be different. A 17psi reading on the gauge with the hose and airbrush (triggers in the neutral position) attached tells me that the bleed valve (if there is one) is open all the way. The simple fix would be to screw in or turn the bleed valve to decrease the exhaust rate. 

I'd rather not go into how a bleed valve controls pressure because it would make the post even longer. If it didn't work I wouldn't be able to paint anything.

Summary:

http://www.sparmax.com.tw/accessories_2.html#amp This link will take you to the Sparmax Accessories page where you can see all the accessories for compressors and airbrushes.

The page will also show you images of 'bleed valves', pressure regulators, etc as well as show a fully assembled moisture trap with a bleed valve (MF8)

Sparmax AC100 Compressors can operate without an air tank.

A bleed valve can be use to regulate pressure by increasing or decreasing the exhaust flow rate. 

If there is no inline pressure regulator there should be a bleed valve.

I hope this helps out in some way, but unfortunately thepuddingcup11 I would need to see a picture of your compressor in order to assist further.

how much paint do usually use for a HG kit, for instance MSA-0011  S-gundam? I don't know whether I'm using too much paint or just the right amount. I tried to air brushed a few pieces and realized I could use up a whole jar of tamiya white enamel (10ml) for all of the white section of the kit.
Thank you

Post by: KaiK on June 02, 2013, 12:25:08 AM
I've painted a HG Unicorn using less than one pot of Mr Color White (also 10ml). Mixture was 1:3 paint:thinner.

White is one of those colours which often require a few coats to get a nice solid finish. It's been a while since I've used Tamiya enamel paint in an airbrush but I do remember using a 1:3 mixture.

If you have a double action airbrush you can save quite a bit of paint by playing around with paint flow and pressure.

Post by: xtoppable on June 02, 2013, 04:36:00 AM
Isn't that really thin? I did with 1:1 ratio and found some paint dripping.
Title: Re: Air Brush and Compressor Discussion Thread
Post by: KaiK on June 02, 2013, 09:52:38 PM
1:3 paint:thinner is a thin mix but it is a mixture that I'm comfortable to work with at 15-25 psi. I overcome the issue of paint dripping by controlling the paint flow.

Less paint flow, less drip, faster dry time per coat.

The trade off is painting can take more time as it needs more coats, however due to the thin mixture I'm not too worried about a thick layer of paint building up.

1:1 is a pretty simple mixture to work with. You can spray at a higher working pressure (25-30+ psi) for fine lines or paint a large surface area really fast. The downside to a 1:1 mixture is it gives you less margin of error when it comes to controlling the thickness of the paint layer and you can consume paint really fast, which was your main concern.

By controlling the paint flow at certain working pressures can give you a similar consumption rate to a 1:3 mixture. Keep practising with your airbrush and you will find an efficient configuration, in the past I practised using plastic spoons, cheap test bed and if the spoon melted it served as an indicator of too much thinner in the mix.

Okay, Im about to out myself as the rookie noob i am, but heres some questions:

I need to spray some Tamiya acrylic/lacquer bare metal as a base coat, for chipping.

Can I:

*Thin it using, automotive acryl/lacq thinner?
*Spray it over vallejo primer?
*Then spray, water based acrylic over it and vallejo brand matt finish?

Also, I've got some aqueous gunze acrylic, am i able to thin it with airbrush medium and distilled water???

Thanks in advance guys.

It will be difficult to say what will happen when mixing automotive thinners with hobby paints, although I'm sure the automotive thinners will keep your airbrush nice and clean if used as a cleaner.

I would recommend using same brand paint and thinner combinations to avoid any potential problems.

So disregarding the use of automotive thinners, you will be able to spray Tamiya acrylics and lacquer bare metal (I'm not 100% sure exactly which product you refer to) over Vallejo primer (very tough primer, lacquer paints should be fine on it) and on top of that you will be able to spray your water based acrylics and Vallejo matt finish.

As for your last query, you can thin Gunze acrylics with a water based medium and distilled water however if you're using the medium often you won't need additional water in the mixture. Always test before spraying your project.

Thanks Kaik, I might just stick to the tamiya thinner although a guy in the LHS yesterday mentioned that you can thin tamiya acrylic lacquer with metho, although im not keen to waste a brand new pot to find out.

Lots of hobby shops around Australia will carry the Vallejo brand, if they don't have the primer on hand they should be able to get it for you.

Alternatively you can find them on online shops such as BNA Models, Lucky Models and HLJ.

Have a read through this thread about priming:

http://gundamaustralia.com/forum/index.php?topic=176.0

Some forum members use an alternate primer for their hobby.

Yes, i've used their paints. They're kinda like Mr. Color but I find that it dries a tad bit harder. Thinner wise, I've only tried their Metallic thinner (t-09) for their metallic range. I know I've mentioned this a million times already, but you should really give their 'Super bright ...' metallics a go. Also, for thinning their non-metallic paints, you can just use general purpose lacquer thinner instead which is about $40-45 for 4L (last time I bought mine).

Hey guys,

So I was base coating the last batch of parts for my Gouf this morning and when I finished and disconnected the brush there seemed to be water between the hose seal and the brush seal, would this be because of the regulator no longer grabbing the water? Is there a way to fix this or is a new regulator needed? it is only a little over 12 months old with not very extensive use.
Title: Re: Air Brush and Compressor Discussion Thread
Post by: TheGhostofZeon on November 10, 2013, 12:02:08 PM
Put an inline water trap between the end of the hose the the air brush.

The one at the compressor end will get the water straight out of the compressor but not what forms in the air line. When the warm air comes out of the compressor and hits the cooler tubing, thats when condensation occurs which will then be trapped if you add an inline water trap at the other end of the hose. If you don't, you will end up spraying blobs of water with your paint and ruining your work.

Hey guys I have made the decision to get myself an airbrush and was looking at all the info on here, and was trying to decide what to get.

I saw this compressor on eBay and thought it looked pretty good, any thoughts?

As for airbrush I was looking at the ab-120 from runway 13 but it seems to be out of stock ATM. Is the complete set worth the extra $40?

I know a lot has been said already but store inventories Change all the time!

That compressor would one of the better toys. It's got pretty weak specifications and for about $70 more you can get a decent one such as the one below. They are a bit noisier but are superior in every other aspect for only a little bit more. Most industrial supply shops will have that or something similar.

What are the specs we should be looking for in a compressor. Also is it normal not using an in-line water trap at the brush end cos I don't seem to be getting any moisture anywhere even when the compressor is running hot constantly?

My regulator doesn't fill up with moisture like it used to either but seems to be constantly leaking air even after I close it up

If you can afford it start with a good one. If it's not your cup of tea you can always sell it but if you buy a cheapo set up you'll be stuck with it. The more expensive AB's are really worth the extra if you plan on building and painting heaps of models.

The Stinger or a compressor of a similar type is usually around 1.5HP, direct drive, 6lt or slightly bigger tank (any bigger and the price starts to get up there), pump output of 100 l/min (that way it only runs for very short periods to top up the tank) and a pressure of 100psi. These compressors usually only take around 1 minute to fill the tank and seeing as you are only running the AB at around 30psi max the tank takes quite some time to bleed down and when it does kick in to top up it's only for a matter of seconds. With this set up you don't need a moisture filter on the AB, just use a combined regulator filter at the tank. I won't bore you with the nitty gritty but most of the moisture if not all of it ends up in the bottom of the tank and there is a drain to remove it. As these compressors never really run hot, moisture is not really an issue like it can be with the toys that flog their guts out just to keep up.

Post by: thegunny on February 12, 2014, 09:35:46 AM
Forgot to add that where you live can play a big part in moisture in the system. If you live in a humid area such as Brisbane or the like you will get a lot more moisture in the system than if you lived down south in the drier areas. But as I said the better the compressor, the less this becomes an issue.
Title: Airbrush beginner findings...and questions
Post by: dagezou on February 24, 2014, 05:43:08 PM
I recently took the plunge and decided to get a compressor/AB.    It's been interesting and I've found that trial and error is the best way to discover stuff rather than copying what others have found, although there is some great info on the net.  I have a sparmax dh-103 which I really like but also got a Runway 13 Nozomi for reasons I'll go through below. Here's my findings so far on various paints:

Tamiya Acrylic & Mr Hobby Aqueos:   No problems.   Only issue here is finding the right ratio for paint/thinner.   I use Tamiya thinner for their paint and Gunze for theirs and they both look equally great.    I tend to thin paint a lot (start with thinner then add paint rather than the other way round) to get it cleanly through the .03 nozzle on the sparmax.  I'm really happy using these paints.

Vallejo Model Air:  Now it gets interesting.  Spraying this is an exercise in trial and error.   The solid colours work great on the sparmax, for example I can spray their acrylic primer with the sparmax no problem.   BUT...their metallics are different.  All of them.   Vallejo is kind of known for having great metallics (for an acrylic) but what I'm finding is that the metal particles in the paint just do not pass through the .03 nozzle.  The AB clogs right away, even if I use (a lot of) Vallejo thinner.  So I got the Nozomi because it has 4 needles including a .05 and .07.   Works much better but a pain.   Vallejo paints won't be a regular on my bench, even though I love the pre-mixed idea as well as the eye dropper bottles.  Initial tests with the larger nozzle size are good.  It sprays much better.

Mr Surfacer:  Same issue as the Vallejo paints...it just sprays better from a larger nozzle.   Have tried Mr White Base 1000 as well as Mr Surfacer 1000 and both liked the larger nozzle better.   I'm  not sure this is an AB issue, it may be my ratio since it doesn't seem to have big particles but I haven't used it enough to get a complete read on it.

Gainotes:   Oh man this paint is the BOMB!   Thinned up nice and thin and using the sparmax,  it's a beautiful paint.  Very nice.   I was a bit scared of laquer based paint before I tried it but I'm hooked now. 

Still to try from my bench: 

Mr Hobby laquer paint.   Just haven't needed my Gundam colours yet but I expect this to be as good as Gaianotes.
Humbrol Enamels.  A bit scared of yet another type of paint but I really like Humbrol for brushing so I'm expecting good things.

Questions:

1. Am I on the right track regarding metallic paint  and needle/nozzle size or is it my mixing/airbrushing causing issues with the sparmax and clogging?

2. Clear coats....do you always need to match clear coat type with the paint underneath it, ie do you need to use acrylic clear over acrylic, enamel over enamel and lacquer over lacquer or can you mix and match?  I've only tried the Vallejo Model Air flat clear acrylic over Tamiya and it worked well (another sparmax clogger though).

3.  Using a bigger needle/nozzle REALLY ups the paint use (and air use, damn compressor comes on all the time using a .05)...should I be doing anything to counter this or can I always expect to need (a lot) more paint if using a bigger needle/nozzle?

4.  Can I expect the same issues I had with Vallejo metallics on others?   I have no issue spraying colours like Tamiya Metallic Grey or Gunze Steel Red so I'm hoping that it's a Vallejo-only issue but haven't sprayed Humbrol/Gaia/Gunze lacquer metallics yet so don't know.

Mod edit: merged with existing AB topic.

Upon reading on this thread, I have decided to acquire this as a starter compressor. http://www.princess-trade.com.au/cart/dynamic-power-1-6hp-air-brush-compressor-with-tank-metal-case.html#

But It seems that I cant turn off one of the valves, for some reason the on/off knob isnt working, its just always on. lol
I'm very new at this thing so I was wondering is there a safe way of "covering" on of those valves so I can build up pressure?

I really don't know why people buy these toys when for around $40 more you can have yourself a proper compressor  :-\ anyway on to your question.

I don't quite understand it but if it's what I think it is, just block off the airbrush outlet that the faulty tap feeds. You can get blanking plugs from any industrial tool outlet. Make sure you take the compressor with you so they can match the thread.

Lots of talk about compressors :) I'll give a run down on the princess trade one I have (same one as the one linked 2nd post above mine)
- loud
- runs hot
- slow to refill, doesn't turn off while I'm airbrushing
- pressure varies greatly while refilling

It does the job, but it's too loud. Anyone have recommendations for a decent, quiet compressor? I have a water trap/regulator already but most of them seem to come with them anyway.

Also, I have a cheapo dynamic power spray booth which doesn't remove as much paint particles as I'd like. I know gunny built one from scratch (with impressive exhaust piping from what I recall haha) but I'm not confident in my handiwork. Does anyone have experience in something like this: http://www.stanbridges.com.au/shop.SPSB88. The price seems exorbitant, but there's not many other options :(

Post by: thegunny on March 14, 2014, 03:12:05 PM
That's not much better than the one you've got. It has the advantage of a replaceable filter but its airflow is pretty ordinary, especially for the price. The flexi duct that it comes with will also knock the flow right down as it does with any type of air flow.

I just brought the new Iwata Neo TRN1 airbrush.

Game over!

I've never had an airbrush that is so easy to use. Just adjust the needle for the type of spray you want, point and squeeze. I've had and got some mega dollar ABs and this thing just puts them all to bed. Iwata reckon this AB is for beginners. Well paint me purple and call me a noob because it's the only AB I'll be using from now on, as a matter of fact I'm about to order another one. At $125.95 all up you can't go wrong  :)

I got mine from this place: http://www.ebay.com/itm/Iwata-Medea-NEO-TRN1-Gravity-Feed-Trigger-Airbrush-N5500-/360899696276?ssPageName=ADME:L:OU:AU:3160  (http://www.ebay.com/itm/Iwata-Medea-NEO-TRN1-Gravity-Feed-Trigger-Airbrush-N5500-/360899696276?ssPageName=ADME:L:OU:AU:3160) Way cheaper than anywhere else.

The stuff that Bunnings or Masters stock are not that good a quality. Okay for starting out but when you can get an Iwata for $125 why bother with the junk.

See post above.

I just brought the new Iwata Neo TRN1 airbrush.

Game over!

I've never had an airbrush that is so easy to use. Just adjust the needle for the type of spray you want, point and squeeze. I've had and got some mega dollar ABs and this thing just puts them all to bed. Iwata reckon this AB is for beginners. Well paint me purple and call me a noob because it's the only AB I'll be using from now on, as a matter of fact I'm about to order another one. At $125.95 all up you can't go wrong  :)

I got mine from this place: http://www.ebay.com/itm/Iwata-Medea-NEO-TRN1-Gravity-Feed-Trigger-Airbrush-N5500-/360899696276?ssPageName=ADME:L:OU:AU:3160  (http://www.ebay.com/itm/Iwata-Medea-NEO-TRN1-Gravity-Feed-Trigger-Airbrush-N5500-/360899696276?ssPageName=ADME:L:OU:AU:3160) Way cheaper than anywhere else. Paid on the 10th, it arrived on the 17th and I used it today. My Badger Crescendo & Tamiya HGII are great ABs but this is just so much better.

Just bought this brush on your recommendation, hope it's as good as you say it is.

Hey everyone.

I've been reading into airbrushes and found that there are 3 top brands. Iwata, Badger and Paasche. I don't think I am ready to spend that much since I am new to airbrushing.

I remember a member by the name of theghostofzeon mentioning he uses a non branded AB-134B Airbrush from Runway13 store. I am thinking of getting it as well since he said that it is really good, just without high cost of branded ones.

I need help choosing a air pressure from Runway13 store. I want to get everything from one store. If someone could please help me pick one out from their store.

Cheers

The only compressor they've got is an overpriced piece of junk so you're going to have go elsewhere to get all you need.

That airbrush is nothing special and a bit pricey for what it is.

Check this out for airbrushes. You'll get a good one for well under $140 and they will get it within about two days. http://www.1999.co.jp/eng/list/364/2/1 (http://www.1999.co.jp/eng/list/364/2/1)

As far as a compressor is concerned you can waste your money on toy airbrush compressors or you can get a real one for around $140 such as these from Autobarn (or any good auto parts outlet) https://www.autobarn.com.au/powerbase-2hp-25lt-air-compressor-pb-02021 (https://www.autobarn.com.au/powerbase-2hp-25lt-air-compressor-pb-02021) They are a bit noisier but 10,000% better.

Oh wow, thanks thegunny. I never knew Tamiya had airbrushes. I just read a few reviews and they are very good. Also read up about Airtex and it is also good. But Airtex has so many AB that I have no idea which one to choose.

Since I am starting out would it be worth it getting the double action over the single action?
Title: Re: Air Brush and Compressor Discussion Thread
Post by: thegunny on February 18, 2015, 04:47:00 PM
Double action ones are harder to use than single action so technically the single action would be considered more the beginners airbrush.

I've had some pretty strange discussions with some "experts" over this but I reckon that if you are going to do it get the best you can afford. If it turns out its not for you then you can sell the set up fairly easily and won't loose much. If you buy el cheapo crap there is a distinct possibility the airbrush could be a dud and that may influence how you feel about using it and you will have a hell of a time getting rid of it. And I don't put any credence in the old "oh you can use the el cheapo for clear coats or primer or whatever". IMHO that's a load of garbage. Why would you spend hours and hours and many dollars getting the perfect paint job then attack it with a crappy airbrush for the final coat  :o :o :o

Some people swear by the el cheapos but through my experience they are just a waste of money. In the world of airbrushes the old saying of "you get what you pay for" couldn't be more true.

Just for the record. I've currently got a Delta (which is a Sparmax, which is a [insert name here]) el cheapo, a Badger 200, a Badger Cresendo, a Tamiya HGII and two Iwata Neo TRN1 trigger types. The Delta crapped itself after the second time, the Badger 200 is 25+ years old and still going strong, the Cresendo is a great AB for Vallejo type acrylics, the Tamiya is excellent and the Iwata Neo is the best.

Here's an Aussie seller for the Neo. Pretty darn good price too.

Thanks for more info and ebay link. I think I'm going to settle for a Tamiya single action AB.
This particular one.

Other than the AB, compressor, hose, spray booth, should I get anything extra that might help me out?

Just the usual consumables. I know everyone says they use this or that to thin their paints but for what it's worth I stick to the thinners made for the paint by the same company. You don't use a great deal so it doesn't really cost any more. I've painted well over 20 large models with mostly Gunze acrylics and I still haven't emptied the first 600ml bottle of Gunze thinners I brought about 5 years ago.

Get some IPA to do the cleaning with, don't use the thinners otherwise you will go broke. Try and get a 20lt container as opposed to the tiny bottles that are sold in the hardware stores. It works out at about 1/50 the cost. Diggers sell it in that size. Make sure you get some specialised AB cleaner (I use Vallejo) and use it for the last bit of cleaning then leave some in the AB after you're finished. Gets out the stubborn muck and also helps preserve the AB innards.

Check out theses do dads as some of these things come in real handy. http://www.1999.co.jp/eng/list/2122/2/1 (http://www.1999.co.jp/eng/list/2122/2/1)

This deal popped up in my mail today. I kinda need a compressor and hose for the airbrush I ordered. The toolkit doesn't look that useful for me but would that compressor and hose work for gunpla? Just curious.

Hi masters, I need your help. I want to learn how to use an airbrush for my gundam, problem is that I don't have much budget for a costly compressor set. Can you please name some of the cheapest mini compressor set, it's pros and cons and where to buy it?

Thanks

Hi Gunny, I am new to gundam & airbrush, and i've just bought iwata neo trn1 after reading your discussions. I'm considering to buy scorpion compressor 2HP as well. Is there any additional items such as moisture filter, regulator etc that I need to purchase separately? Thanks
Title: Re: Air Brush and Compressor Discussion Thread
Post by: thegunny on February 11, 2016, 07:25:27 AM
The pressure is on  ;)

it's up to you how much you spend on a regulator & moisture trap. I'd go for a combined unit (even though mine are separate) as they take up less space and are usually cheaper. On the subject of price these things really are a get what you pay for item. Cheap regulators may need to be constantly adjusted and will leak eventually. The best bet is to get your set up from a tool store as opposed to a hardware or auto store.

Just remember that the Scorpion is louder than the toys but runs for a lot less time and being a heavy duty type compressor (relative to the toys) it doesn't run for very long during a paint. Believe it or not I've never drained the moisture trap on mine as it's so underworked it doesn't get hot enough to generate much moisture.

A decent Scorpion 2Hp 55ltr compressor costs no more than the toys that are sold as so called airbrush compressors. You get what you pay for with airbrushes  :)

I'm sure if you got through this topic you'll find what you need.

Thanks Gunny for your quick reply. Autobarn also sell scorpion regulator/filter, hope they have someone to fit that in for me.

https://www.autobarn.com.au/scorpion-filter-regulator-1-4-sfr-302

BTW, eBay is having 10% off for all item above $100, and autobarn has shop on eBay. Perfect!!!  ;)

Here's where I got my iwata neo trn1, cheaper than eBay  :D

go to ebay and search for airbrushes ... you can get them for about $20 - nice double action, with gravity cup.

buy several.
easy to use and maintain

since they are cheap, you can basically go through about 10 before you reach the cost of Pasche or Badger airbrushes.

as to learning how to use - search youtube for airbrush tutorials take what they say as a guide.
site down with an old model or sheets of paper and just spray some paint. 
go back to the tutorials and rewatch ...

as for compressors ... well, i've had a Pasche compressor for 15+ years now, i'd say spend the money here, this cost me $250 at the time. 
A tank is a must if you want to get serious ... get a full rig, might cost $400 but it is worth it ...
definately a moisture trap with regulator - don't skimp ...

Thanks Cob for the tips

Has anyone use Vallejo rc premium to airbrush your gundam? The reason I'm asking because it's cheaper (around $8 for 60ml) than their 'air' product line, but I can't find any review on them for gunpla. Here is the brief description of Vallejo premium paint

AV PREMIUM is a safe water-based, non toxic and highly versatile airbrush ready paint, suitable for all surfaces, but especially formulated for superior adhesion to metals, fibreglass, polyethylene, clear Lexan™ polycarbonate, slot car and RC bodies, and all tuning and automotive applications.

Hi everyone, i've done further reading on Vallejo premium paint and found the recommended compressor setting for this paint is 30psi. Would it be a problem since people normally use 15psi setting to airbrush gunpla? Will I still be able to use this paint with 15psi setting? Thanks
Title: Re: Air Brush and Compressor Discussion Thread
Post by: thegunny on February 15, 2016, 09:20:41 AM
Gunpla is no different to any other model so if that's what Vallejo recommend then that's what you should start out using. You can muck around with the pressure to suit yourself and whatever airbrush you are using as you are spraying.

Post by: Newbiegonecrazy on February 15, 2016, 11:02:35 PM
Thanks again Gunny for the tips. Sorry I have no idea about airbrushing & I've bought 20 of vallejo premium paints. I was a bit worry there, cheers!
Title: Re: Air Brush and Compressor Discussion Thread
Post by: thegunny on February 17, 2016, 08:24:57 AM
You don't see much about the premium paints because they don't really market them to the plastic modeller but they are quite popular in the RC world. They have a good colour range especially the metallics & candies. I've been meaning to try some myself but up until just recently hardly anyone stocked them.

Hello guys, can you give me a brand of a reliable airbrush set that cost less than 250 aud. The cheaper the better. I'm planning to buy but I don't know which one to buy. Please help. If you can give me a store link please. I'm live close to Sydney. Thanks

Iwata are one of the best.

These two places seem to have the best prices in Aus (you can get them better from Japan in some cases)
Adelaide Molding & Casting Supplies: http://www.amcsupplies.com.au/index.php?main_page=index&cPath=2003_2208
Airbrush Mega store: http://www.airbrushmegastore.com/index.php?option=com_virtuemart&page=shop.browse&category_id=1705&Itemid=88

I've used both and they are pretty good. Be warned the other big Australian store, the Airbrush Shop are way overpriced compared to these two.

If you want Tamiya or Gunze airbrushes Hobby Search are a good source. They get them in and posted within a couple of days if they aren't in stock.
