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 !!\
