The relationship between follower radius and cam lift / profile is properly complicated. The master cams you have may well have been made assuming a specific follower radius. If the master follower, the grinding wheel and the engine-as-installed follower are the same radius then it is easy, otherwise there are two sets of corrections to apply. Machining a cam for a bucket follower with a lathe tool means correcting for infinite radius in the engine and zero radius in manufacturing. I looked at the equations in a book once. But I have never made a cam for a purpose (I just set up the lathe to prove that I could) -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifest ------------------------------------------------------------------------------ Time is money.
