I tried this trick a while back when I was trying to buff some scratches out next to a weld. Ya'll might think I'm nuts, but it worked both times.

Regarding the wheel speed, one thing I can figger is that the "centrifugal" effect is flinging the wheel threads out there with less force at lower speeds, hence slapping the workpiece not as hard. If that's how it works then a smaller wheel at the same rpm's might have the same effect (?).

Far as the wheel position...yep I think you're nuts but so am I, lol. Could it be that on the front side of the wheel the threads are not fighting gravity and so are more "free-floating"? Spacey territory....

Anybody know if a rheostat would burn out buffer motor?
