I'm no machine shop guru, but it looks like the Baldor buffers in the
Eastwood catalog are rated at 3600 rpm. They recommend a lower rpm for
plastic. So if you're buffing metal, you're in business. If you're
buffing plastic, get an old washing-machine motor (no, really, it works
great!)
On the airbrush subject, If you can find one with gravity-feed, that's
preferable for heavier materials. We use an Aztek for little stuff at
work. It's plastic, but the claim is that it's solvent resistant. For
larger stuff we use an Iwata RG-2 which is almost a touch-up gun. A
single-action Aztek can be had for around $50-$60.
