airbrush needle positions

[Digger1]

If anyone had or can take pictures of their airbrushes in various configurations that create a fine line vs. a large spot. I had a Badger 150 and I had trouble with it because I didn't know how to regulate to air flow and a lot of paint came through. It occurred to me recently that my needle might have been in the wrong position or the screw at the rear of the airbrush under the cowling (blue counterweight).

So, if you can provide some pics of how everything is supposed to be, it would be appreciated!

I've got a pair of Badger 100's which are basically gravity-fed versions of your 150; internally the guts are the same:

When you re-assemble the brush after cleaning, start with these two pieces:

The larger part is spring-loaded, so screw on the needle chuck to hold the parts together:

While making sure the trigger and the little crescent shaped piece are properly seated, screw this assembly into the brush until it stops, and no further (don't screw it down tight):

Now remove the needle chuck screw:

While gently holding the trigger back, GENTLY insert the needle as far as it will go. Release the trigger and screw on the needle chuck finger tight:

The needle should now be seated as far forward as it will go:

I own two of these brushes, one with a medium tip and one with a fine tip. The medium brush will do amazing fine lines with thin paint and low air pressure. Hope this helps.
