Hi Gunner,
I looked at the link that you provided and am totally confused.

"Suppose you want to impress a diamond knurl on a 1"-dia. shaft and the distance between each tooth of the knurling tool measured, with calipers, along the roller's axis is 0.060"

How do you measure the distance between each tooth "along the rollers axis"? The teeth are on the rollers circumference aren't they? What am I missing?

Thanks,
Ivan Vegvary
