airbrush problems

A while back I bought myself a internal mix dual action airbrush to replace my plastic external mix one. I played around with it a bit, see what effect the different nozzles had. When I replaced a nozzle, I first filled the gravity-feed cup with turpentine, and let it spray through the nozzle. Bout halfway through, no more pigment would come from the airbrush, so I figured it was clean. I sprayed the enire cup anyway, just to make sure no paint was left inside. When this weekend I wanted to start painting a model, no paint whatsoever came out of the airbrush. Any thoughts on what is wrong and how I could fix it? Kinda reluctant to believe the nozzles are clogged with paint, but where else could it be?

You need to completley take apart and clean the airbrush after EVERY painting session. Here is a link to my website:

That's the truth. The more shortcuts you try mean the more chances of failure when you want to use the tool again. Just practice taking it apart until its second nature. I must say though I would never use turpentine to clean a air brush. Mike

I had that same problem with internal mix airbrushes. No matter how well I thought I'd cleaned them, they would clog. I sent them back to Badger, who cleaned them and told me I wasn't doing it right. However, I could never get it cleaned. That's why I use a 350 external mix. I CAN clean it and make it work. Jerry 47

How nice of the Aztek instruction sheet and instruction video to mention then that tghis is absolutely NOT necessary. Sigh. backl to the drawing board for me :(

Actually, this is quite true. I've been using both the 1000S and the 470 for over a year now and no cleaning is necessary other than spraying 2-3 ml of the appropriate solvent and wiping the nozzle with some dry tissue.

Sometimes, particularly with the double action airbrushes, the nozzle needle can get stuck in its Teflon sleeve. You can check for that by pulling the trigger all the way back and loooking on the tip of the nozzle if the needle is still protruding. If it is, you need to pull the trigger and _gently_ push the needle back using a piece of wood or a bit of plastic sprue; it will pop back and you're ready to go. There's no need to disassemble the nozzle.

Make sure you're using refined turpentine, as the unrefined sort can leave a sticky residue in the nozzle. Or, if you're using enamels, always spray a little of the manufacturer's own thinner. After painting with acrylics, you can spray some isopropyl alcohol. Alcohol-based window washing fluid can do the job, too.

Load off my back. The airbrush itself is fine.

But then, in the Azteks, all the interesting

Both happen

Pressure's right, no screw, and the paint cup port should be clean, not entirely sure on that one. My aztek has two places where you can attach the GF cup, so I switched to the one I hadn't used before, no change.

Not sure I wanna be doing this.....

Another question: if you attach the nozzle and a GF cup filled with water, do you get any bubbles in the cup when you try to spray ?

Nope. is that good or bad ?

Good, but it doesn't solve the problem.
