Can I use this for compounding???
I have an old Black and Decker 9" right angle grinder/polisher or whatever. On the plate with ser. num. and model under r.p.m. I can't read it. There are 3 zero's and it looks like 12 or 15 in front of the 3 zero's. Is it possible this thing is 12 0r 15 thousand r.p.m.??? The guy at the 3m paint store said he wouldn't doubt it. The old ones can be that fast. This baby is all metal and weighs about 20 lbs. I was going to use it for my initial compounding but after reading all the posts and going to the web site links it looks like I need one with about 1000 - 1200 r.p.m.
