>Derek, Thanks for the reply. I use oil stones mostly, but I also use diamond on cast iron lapping plates in certain situations. If the diamond will embed into the cast iron, what keeps it from embedding into the brass wheel? Cleaning the swarf off of the brass will not remove all of the grit. I don't think contamination is avoidable in any instance. I'm really concerned with if the amount of contamination is important.
