Hi all, I'm wondering if my airbrush is adjusted incorrectly.  My trigger has about a full centimeter of travel, yet pulling back even just a small fraction of that will quickly empty the entire paint source.  It seems to do a very low amount of paint at first, but quickly goes to full "on" and finding a happy middle ground is proving to be extremely challenging for me.  I'm wondering if this is common among all airbrushes or if there might be something I can do to allow a more gradual release of the paint as I pull back on the trigger. 

I admit that I am very new to airbrushing so I wouldn't discount the problem being yours truly instead of the airbrush, but I wanted to check in with the pros here for your opinion.  Any help is greatly appreciated, even if it's just for me to practice more.  The airbrush I'm using is the Badger 360.

I am not familiar with that AB but from what you write, I wonder if you simply have the PSI on your COMPRESSOR too high? That could be a cause of what you describe? Get everything ready to shoot paint and check your regulator. When you shoot some paint, look at the regulator and see where the needle goes. There are all kinds of variations of paint dilution vs PSI settings that can be used. Just for research, set your regulator on 10 PSI and see what happens, then put it to 20. Play around with it. Just be sure as you are shooting the paint to look at the regular dial and see where the needle goes when you pull the trigger. I don't know of the badger has a way of limiting the trigger pull? Its usually a matter of turning a knob on the tail of the AB or sometimes up front under the tip, but to set a limit on the trigger pull might help? one of my AB [I forget which brand] has a small knob under the front end that controls air/paint mix separately from me pressing down and pulling back on my trigger---once that knob got out of adjustment and screwed up my paint flow. All my AB are double action. Pushing the top of the trigger down for air, and back on the trigger for paint. Is the badger a single or double action?

Thanks Ted - I think I read that 30psi is standard pressure for airbrushing and that's what I started at.  I've since reduced that to 25 along the lines of what you recommend however I didn't think to go as low as 10.  I will try that and see if things improve.

My AB is dual control as you note - push down for air, pull back for paint.  There is a photo of my brush available here: http://www.badgerairbrush.com/Universal_360.asp

Thanks for the help - I'll report back how it goes.

sounds like a good plan--hope it goes well.

In regards to pressure setting, some use different pressures, while some seem to stay with one pressure range and vary other factors--paint dilution, etc. AB is a relatively long skill curve IMHO.

Ok so I still have this problem, however things have improved.  I performed a thorough cleaning of my needle and this definitely helped.  In doing so I learned some about how the brush actually works and this also helped a bit.  Ultimately, I still find the point at which the brush goes from a little paint to 'holy crap that's way too much' is difficult to control, but have concluded that it's likely something I just need to get used to.

I wouldn't mind trying out some other brushes to see if there are any that have a less sensitive trigger.  It would be great if there was a place where something like that might be possible although that seems unlikely...

Does it have a limiting screw on the rear section?

I got a extra one for my Neo and it's a good (if a little lazy) way to dial a bite point in and have it set perfectly

In the AB instructions from the link above, (you click on the image of the AB) there is a section on adjusting the trigger spring. Have a close look at that and refer to the exploded view of the AB components. Adjustment of the trigger pressure might help? Or I might be totally off base! Yikes!
