Needed: Airbrush Equipment Basics and Recommendations

Recommended Posts

I know a bunch of you guys use airbrushes for various projects. I have the crappy EE hand flamer version, and it's fine for terrain, but I want the real thing. I have a small collection of large models I want to paint, not to mention C'thuhulu and those dragons that are coming next Spring and I want to be able to do these models justice.

 

what do I need to get started? what kind of brush? what kind of compresser? what are basic do's and dont's of mixing the paint? any other really good advice?

 

I appreciate any input you airbrushers are willing to provide.

That's a pretty good article although its still missing a couple of things. So let's dive into my setup and what that article is missing.

I have two airbrushes; an Iwata Eclipse HP-C and a Harder & Steenbeck Infinity. Both are dual action, gravity feed airbrushes. I much prefer the gravity feed over the siphon feed, there is just that much less to go wrong. I love both of these, the Eclipse is my workhorse and the infinity is my smaller detail brush. However, you really only need one airbrush, a good dual action brush will probably serve your needs quite well. I have bought all of my equipment from http://www.chicagoairbrushsupply.com/

 

My compressor is an Iwata Smart Jet pro, incredibly reliable and very quiet. However, you don't need a fancy compressor you just need one that that pushes air and in the case of the cheaper compressors has an air tank so that you don't get pulses of air through the brush. Often though a water trap will help relieve this condition. I don't recommend the big 3-5 gallon tank compressors they are very, very loud. So not worth the effort unless you can leave it in the garage and run a long line to your airbrush.

 

The real key to learning how to airbrush is learning how to clean your airbrush. This is the cleaning kit that I use and recommend http://www.chicagoai.../maaiclkit.html don't even begin to think that you can get away without this. If you don't have proper cleaning tools, you will probably be tempted to throw everything in the trash from frustration.

 

Learning how to use the airbrush itself really isn't that hard (I learned how after all). The first key to airbrushing is learning to thin your paints properly. I use a mixture of 10% Isopropyl Alcohol (99%) and 90% distilled water (this is the only time I use distilled water for painting, mineral buildup inside your airbrush is a very bad thing). This is not exact mix, its kind of like baking if I'm close that's good enough, don't get to hung up on ratios. I usually have three or four bottle of this mix at hand as well as a couple of bottles of regular distilled water at hand (and clearly marked). I thin paint and clean my airbrush with this mix. Some people swear by windex as a thinner and a cleaner (and I have used that) but windex can attack and destroy the o-rings in your airbrush. If I'm using regular acrylic paint (Reaper Master Series, Reaper HD, Vallejo Model or Game color) then I usually start thinning at 50/50 paint to thinner. I have little cups that I mix the paint in so that I don't introduce large globs or chunks of dried paint into the airbrush cup. Its not an exact science and you will have to experiment from there. You don't want a wash but something that will flow easily through the airbrush and give you good coverage all at the same time (and its not as hard as it sounds). I use a lot of Vallejo Model Air colors but never straight from the bottle, these are always thinned down a bit as well. If your paint is beading on the surface of your mini or model then you are much to thin.

 

The second key to airbrushing is learning why your airbrush is clogging and it will behave differently depending on where it is clogged. A dual action, gravity feed can clog either in the area where the paint and the air are mixing or right up in the tip where it needs to come out. Sometimes do short spritz's (release the trigger and let the pressure build up) will clear it, sometimes unscrewing the back and pulling the needle out a short distance will also clear it, depends on the type of clog. If neither method works then you will have to take it apart and clean it. Believe me, you will get very good at this. I can dissemble, clean and reassemble my airbrush in under 5 minutes. You don't have to do a complete clean to change colors either. Just pour out any remaining paint, wipe out the cup, shoot some water through it until it comes out clear and then you can go to the next color. A complete cleaning should be done when you are finished for the day. You really don't want paint to dry on the inside over night.

 

Also really give this some thought before you dive in. I paint a lot of miniatures and for some jobs (like vehicles) or large numbers of miniatures that are basically the same color an airbrush is the way to go. If you think you are going to paint your entire 28mm miniatures with an airbrush, I have some some swamp land in Florida for sale. Here is an example though of a piece that I have laid all the basic colors in with the airbrush (this piece was primed black):

And when you have a lot of horses to paint.

And some detail work (everything on these horses was airbrushed, they are 28mm)

Okay, it looks like the 1st and 2nd one are the same basic airbrush, while the third one is a bit different. These aren't going to be bad airbrushes to learn with; dual action, gravity feed. I suspect that these are Master Airbrushes out of China and they greatly resemble Iwatas. I have seen people get some great results with these and its hard to beat the price. The issue I have with these is cleaning.

 

If you look at this one: http://www.ebay.com/...=item1c1f5bda81

 

You can see some great pictures of the whole thing in pieces. Scroll down to the 4th picture, which is split between a close up of the front end of the airbrush and the gravity cup on the right. When you look at the needle you can see the needle, the piece that the needle comes through (which is removable for cleaning) all of which sits atop a brass piece. In the high end airbrushes this brass piece is removable for cleaning. If these are Master Airbrushes its not and if its damaged or clogged in the right way you can basically through the airbrush away as its part of the main body. That being said it doesn't happen very often and you could go years without this happening.

 

So these are not bad to learn on especially considering a name brand airbrush is going to run you at least $100 (although you can get some good deals out there sometimes).

 

As far as compressors, the hobby compressors just tend to be quieter. Having a tank style hobby compressor allows the compressor to not be constantly running. The high end hobby compressors tend to be very quiet with automatic shut offs so if you aren't spraying paint the compressor is not running.

 

Any compressor that you can step down to feed air to the airbrush and you can control the PSI on will work just fine. Its mostly a matter of noise as those types of compressors typically are kept and run in garages where noise is not an issue. I think that Harbor Freight makes a pretty good little compressor for airbrushes that isn't to bad.

I'll step in and advocate for the home improvement type of compressor. I use one and it is loud, but it only runs once an hour and costs less than $50 with fittings. (on sale) It has a three gallon tank, so it does not have to run often. I put it in the closet, so the noise is not an issue. Finally, I now have an air compressor for filling low car tires and such.

 

If you live in an apartment and paint late into the night, this is not an option for you.

Let me put in my two cents,

 

I picked up this poorman's Iawata from Ebay

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=140622287127

 

I then went and got a 10 foot plastic 1/4in tubing from Menards and a Toolshop compressor.

In all the whole set up cost me about 90.

 

It is loud but I have been able to use it with decent effect. There is a great deal I need to learn. As for the cleaning kit recommended, I listened to a presentation from the president of Badger and he said that those kits will muck up an airbrush and void your warranty. Just an FYI

So what did the guy from Badger recommend? I have used this kit literally for years and I don't have any problems with my air brushes. Now that being said, one of those little cleaners is almost like a router bit and its designed to scrape at point in a very small space and it certainly can (and does) damage your airbrush.

 

EDIT: I just went out to the Badger Airbrush site and they don't actually make a cleaning kit of any kind. So I'm definitely curious what Badger recommends to clean their airbrushes.

Fantastic! That airbrush type is actually called triple action by Iwata. The dial on the front bottom of the airbrush is for an additional level of atomization of the overall paint and air mix. Larger drops, no problem, finer drops no problem as well!

      Reaper Challenge League 2022
      1) Intro
      2) How It Works
      3) Types of Challenges
      4) The Raffle

                         PDF Check List               Discord
                         
      Intro:
             Welcome to the Reaper Challenge League (RCL), a system that rewards fans for completing community-based events and challenges. This will all be conducted via the Reaper Miniatures Discord, where there is a system in place to track points and administer raffles easily (see below).

      THIS IS NOT A CONTEST ----- This is meant to be a challenge against yourself to see what you can accomplish, not a contest to compete in against other people in the community. So enjoy your time in creating stuff and have fun doing it with everyone else!

      Only Reaper minis will be accepted except for in the Freebie/Bust categories. You can use any paints for submissions, the only exception is the Limited Palette challenge.

      How It Works:
      Users can submit photos of RCL projects on the #submissions area on Discord and receive points depending on the tier of challenge.
      These points can then in turn be used to purchase raffle tickets which will be drawn quarterly, with a large annual raffle at the end of the year. Only Reaper minis will be accepted for submissions, except for in the Freebie/Bust categories. You can use any paints for submissions, the only exception is the Limited Palette challenge. Each quarter, a RCL raffle shall be held during the last seven days. This ensures that people have ample time to enter tickets or finish any entries so your points may be exchanged into tickets. On the last day of the quarter, the raffle will be drawn, and winners posted. At the end of the year a larger raffle will occur that accounts all accrued points points you have earned yearly (spent and unspent).  Terms and Conditions may change at the discretion of Reaper Miniatures at any time.

      Type of Challenges:
         All entries must show some sign of trying and not just throwing paint on to get some quick points. In keeping of the spirit of the league, challenge yourself and see what you and others are capable of. The amount of points that each one challenge will grant are in the () below, as well on the PDF for the 2021 chart. Reaper Challenge League PDF
       
       
       








      The Raffle:
           The raffle will happen the last 7 days of each quarter, This will ensure that people have ample time to enter their tickets or finish any entries they need to complete before drawings. Tickets will be pulled on the last day of each quarter!
          This will all be done on the Discord server, as we have a bot that is programmed to keep track of members points and how many tickets they have. We will use this bot to open the drawing and for you to enter and participate with the system. The drawing will stay open for one week before doing the drawing on the last day at a set time!

      Thank you, the team!

      Frequently asked questions
       
      Q: I am just wondering if one model can be turned in for two different categories? 
      A: In the spirit of the challenge, we would like it if you submitted a different model for another challenge. As this isn't a contest and meant to get people hobbying. 🙂 so you would just be doing yourself a dissatisfaction!!!!!
       
      Q:  Since the Reaper Discord moves so insanely fast, how will winners be notified? 
      A:There will be a channel that is static that is read only, for raffle winner and other announcements. 
       
      Q: Will the raffle draws be things that can survive through colder climates when shipped? 
      A: Not to sure on the exact prizes but this ties into your third question, I can hold things for you if cold climate is an issue and ship it at an opportune time.
       
      Q: For the Quarterly holiday - what are you looking for for Q1?  Like would just, any winter/snowy model be ok, or do I need to figure out what a MLK day themed model would be? 😜
      A: The rules are very loose, as this is not a contest and is meant for you and others to hobby!!!!!! So if you think its a holiday or a special day? By all means paint something and present it under that challenge category, as long as you spent time and effort into making it, I will recognize it. As an example if you wanted to paint something that was for your birthday! i'll count that!

      I am stunned at my recently arrived Sophie's Revenge, and so excited to get it to the painting table (I will have to significantly reconfigure my painting space to ensure I have enough room...  As well as buy LOTS of new brown paint, ha!)  It is a thing of beauty, even without a lick of paint on it.  
       
      One of the first things I noticed was how the magnetized masts SNAP to the deck, hard.  That's what you want, so they'll stay firmly in place.  But when you remove 'em, they'll likely scratch the heck out of the painted deck.  So I plan to cut disks of black felt to glue to the underside/ magnet-side of the masts, so that when they stick, they're more gentle.  Thin felt should not affect how they stick, but it should make a big difference on the ship's wear and tear.
       
      Are you planning on painting yours?  What strategies are you going to adopt to make it as beautiful as you can, while still keeping it sturdy as a plaything for your RPGs, wargames, or maybe even little kids (don't judge!  mine are gonna be all over this thing!)

      StackaRack is a customisable plastic rack for miniature paints, designed to hold pots or bottles from any of the major manufacturers.
       

       
      Paint collections have a way of growing organically, and most of the current paint rack solutions out there are fixed to specific configurations, and made for a specific type of paint pot. If you're like me, and collect multiple brands of paint, that can make organising them a little frustrating, and so we thought we would try to fix that.
       

      StackaRack was designed to hold any of the major miniature paint ranges - from the dropper bottles used by Vallejo and Army Painter, to the tall pots from the likes of Privateer and Reaper (and GW's old range), and the current stubby Citadel pots. The injection moulded plastic parts will fit together with plastic clips, allowing you to build it how you like, and disassemble and reconfigure it as needed.

      Having recently joined the airbrush crowd, I'm discovering how much i love blasting paint through it.  Saving so so so so much time on my zenithal priming groups of minis.  
       
      Now that I've got the priming and ink through it, I'm curious about another medium going through - varnish. 
       
      I own satin and gloss varnish from liquitex. I've used them as brush on, which isn't my favorite.  I want to know: 
       
      1.  Has anyone used this in an airbrush? 
      2.  If yes, how did you thin it?  Did you use airbrush thinner or something else? 
      3.  Does it require different means to clean after using? 
       
      I'm super paranoid about clogging or ruining this new tool of mine.  I found out Stynylrez primer wasn't just pour in and go.  Made for a fun clean up with my first go at priming.  
       
      There's a ton of stuff I'm seeing on testors dullcote from the bottle and mixing it with their thinner, but I'm hoping to use what i have if it's possible.  
       
      I'm not asking what you use as much as I'm seeking specifically "has anyone used liquitex varnish in their airbrush? "
       
      And... any pictures of your results?

      I'd never felt I had an artistic bone in my body until I started painting minis. Well, now, I decided I'm going to try my hand at 2D art. 
       
      I am following along Bob Ross videos on YouTube. I will note, and this is probably very important, that I am using acrylic paint and not oils. I did not want to spend oil paint prices since this is a new thing for me.
       
      These are the two I've done:
       
      Day 1: I learned a lot, I needed to do something with my paint to extend the drying time. This would have helped with the blending. Overall, happy with it excepting the house.

       
      2: I used some slow dry medium mixed into the paint today. Not sure if it was not mixed well enough or I didn't use enough but it only gave me like 5 minutes or less of extra working time. If anyone has any suggestions for how to use slow dry medium, please, let me know. I'm using heavy bodied acrylic tube paints.
       
      I followed along until the end and I decided to add some darker blue and green. I think that helped a lot.
       

       
      Another note, need to find sturdier paper. While this is holding up it likes to curl slightly while drying. The second one is taped to the desk on the back to try to minimize that problem. I am currently using a mixed media paper.
