You helped spend my money, help me with grinder wheel info

[Jim Underwood]

Since ya'll have helped me spend so much money, how about helping me with a sharpening workshop? :D

I'm looking for a good summary explanation of grinding wheels. I'd like to give a handout for our sharpening workshop next week.

I'm looking for explanation on the stone material and configuration, as well as matching steel to stone, and care and inspection of wheels.

Got some good links?
