But in a nutshell I'd try taking about 10 degrees @ .050 from where you're currently at, and would have it ground on a 112 or possibly even 114 to make it as smooth as he seems to want.

Ask Dwayne to pick it out and give him a credit card number, he'll have it drop shipped from the cam manufacturer.
