Is it ok to use a 10000 rpm motor, with a 5" wheel to polish aluminum, the problem is I keep burning motors on hand held polishers, and the guy at sears knows me by my first name. the original polisher I was using was like a 4.6 amp 2600 rpm 1/2 horse. I have burned out 3. so I went and bought a 12 amp 10000 rpm hand held grinder. is this going to hurt anything but myself? I am polishing various bike parts, some have sand cast, and i am knocking them down with 120, 180, 240, then black, and brown

Years ago, when I made jewelery, I used an old 1/2 hp washing machine motor with pulleys to increase the speed. If you set it up for multi-sheave pulleys, you can get several speed ratios. Also, some of these motors are multi-speed. Induction motors are quite indestructable compared to the brush-type universal motors, and you can often get them really cheap/free if you ask around. Of course, the pieces I worked were pretty small, so a fixed buffing wheel on a bench was okay. If you have large parts, or need to be mobile, this may not be an option for you.
fwiw
