Att'n Badger 100LG users

The Badger 200 has the preset on the handle and it is pretty tough.

Thanks gents.  I would want to use it as a pre-set.  The screw and mount looked a little fragile, and I was wondering how durable it was.

Actually it's there to limit the fore and aft needle travel.  Some people like a lot of travel, some people like only a little.  I change it depending on what I'm doing.  However, if you like using it as a pre-set, so be it; just use it for whatever purpose you prefer.

All it really does is that it allows you to "pre-set" a needle position so that you can use the airbrush as you would a single-action unit. Simply pre-set the screw to a particular position and press the trigger.

Note that it does not prevent you from drawing back on the trigger and increasing the paint flow if you so desire.

Edit: Oops - mis-read your post... You already know what it does.
