Everything else I hook up works fine. I'm pretty sure the sander just uses too much air.
I tried it for a while yesterday with the regulator wide open. It still slows down about the same as before.
I have a 3/8 air hose I can use. I'm going to get high flow fittings. I never used them before. Anything on this page that'll work?
