I don’t think I have how the concept works between the two thumb screw adjustments on the rear of my Badger 200 single action air brush. One is called the “Needle Adjusting screw” closest to the rear housing, and the “Needle Chuck” on the very rear which also screws into the adjusting screw. It seems that both move when I try to adjust the paint pattern.
Should one screw be fixed and only the other move? Which should turn to adjust the pattern and not loosen the housing as well? Is the sequence to put the needle in the brush, screw the adjusting screw tight, and then screw on the chuck screw? If only the back screw moves to adjust, why do they call it the chuck and the other the adjusting screw?
I’m sure some air brushers out there can help me as to the correct operation (which probably should be obvious to me)! Thanks!

Hal,
IIRC, the chuck and adjusting screw work in conjunction to “clamp” the needle. The “clamp” allows the adjusting screw to hold on to the needle so it can be adjusted while spraying, thus both parts will turn. The housing should not turn when you adjust the pattern.
Now, if you can not get a thin enough pattern the needle may not be set up properly. In order to adjust the needles initial position, loosen the chuck and adjusting screw, GENTLY slide the needle forward until is stops and tighten the chuck and adjusting screw. I may take a few tries to get the results you want.
I hope this helps,
Sean
Thanks Sean. It really helped. I get how it works now and I had good success today in getting use to using the air brush.

Hal- I’ve been using a pair of Badger 200’s since the mid-seventies. Should you have further questions, get my e-mail address from my profile and send me an e-mail with your question. I’ll do my best to help. (I’ve been atomizing pigment since the mid-sixties.) Bil
