I ordered the wheel polishing kit and the Zoop seal, and I read through the online buffing booklet, which states:
"For best results your wheel should maintain a surface speed of between 3600 & 7500 surface feet per minute (SFPM).
SFPM = 1/4 x diameter of wheel x RPM"
Why is it 1/4, wouldn't it be Pi (3.14) x Diameter x RPM? Just curious...
Anyway, it seems that a grinding wheel is a good choice, so I will borrow a friend's Craftsman grinder. I can't imagine
not using a flex shaft to polish 18" car wheels with this, but no one seems to sell them for bench grinders. Surely someone has them? I have a Rotozip too, but it runs at 24,000 RPM I think...would that work as well?
