Last I checked, the 3M wheel built for use in my grinder that I use to finish soles on bore thru heads and other light grinding/polishing tasks says 'Scotchbrite' on it. It is supposedly build much different than the $5 one for your hand drill at K-Mart (at least I hope it is - I'd hate to be standing in front of it if it blew apart), but it's still 'Scotchbrite'. I'm not sure what they cost since I got mine from a friend who works in the TM tour van (it's really a trailer, but we'll keep semantics out of it).

Charlie,
You are correct! I was addressing this issue from the standpoint of someone asking about this procedure using something as simple as a 6'" bench grinder in his garage! Doubtful that he is ready to spend a couple of thousand dollars on a machine to grind and then more money for a machine to measure the COR. I wasn't talking about a "scotch brite" wheel either. A finishing wheel costs $50-$70 and that seems to be out of the range of many hobbyists also. That's why I addressed the procedure of applying snake oil. This whole issue is in my mind bullcrap, unless you are prepared to spend the bucks and do lots of heads the right way!
