Hi I have a 3500 RPM grinder and the Beale polishing system for woodturners from packardwoodworking.com. I am trying to polish a thick hard plastic (polyurethane) cube. Does anyone think this is not the correct application ? If this is not the right way, then can someone tell me why this is not good, and make a suggestion as to how to polish hard polyurethane blocks ?
thank you !!\

Might be a bit to hot for the job. Certainly the abrasives would be mild enough, but slower speeds, as from smaller buffs and/or slower motor would be my recommendation. I polish poly finishes with Tripoli and rouge on a
1725 rpm motor, using 4" buffs, and I still have to keep things moving.Have something to add? Share your thoughts — no account required.
