This is more than a little embarrassing.  See, now I've been airbrushing the basecoat on something like four or five dozen models now.  I've done a pretty good job.  There's a couple of Chimeras I got the paint:water ratio wrong on, but we won't speak of that.  But it's always bothered me that I had to keep stopping to wait for the compressor to catch up.

The Flow Regulator
This, ladies and gentlemen, is a "flow regulator".  It's purpose is to reduce the pressure of the air from the tank to something you want to work with.  Pressure inside my tank is about 60 PSI and that comes out the airbrush pretty damn fast.  Causes a fair bit of over-spray but does the job.  Problem is that it empties the tank very quickly which causes the compressor to run a lot.  It also causes paint to 'bounce' off the model causing over-spray and flying models.

This is all because I had the regulator set wrong.  In my defence, I hadn't set it at all.  Turning the valve to the left (loosening it) causes the pressure on the gauge to drop.  You want about 20-25 PSI for airbrushing models without blowing them out your hands and you'll probably find that (like me) your compressor can keep up that pressure all day without a problem (until it overheats, of course).

So that's my first useful tip for airbrushing:  Set your flow regulator and set it right - you should find 20-25 PSI about perfect for basecoat work. Related Posts Plugin for WordPress, Blogger...
