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.
I would not go any faster than 1000-1500 rpms - you will burn the alum

Why don't you use the type that the body shops use?http://autobodystore.net/Merchant2/m...ategory_Code=T This buffer is smooth ,lite, and forgiving. The speed can set with in the range of 600 to 3000 rpms. $189.50 Makita 9227 buffer.
Just got back from harbor freight. They have kit; 9" angle buffer/grinder variable speed 1000 - 3000 rpm and assorted pads for $29.99. We'll see how long it lasts.
I really like my DeWalt....paid 150 for it at harbour freight...

I picked up a 2500 rpm grinder-type buffer from Harbor Freight for $19.99, so far it has worked well, although I would like a variable speed unit. 2500 is just a bit fast, and I have to keep it moving.
