FYI
I'd like to bring to your attention that I have developed a new way to make cams using a CNC mill and an off the shelf mini-grinder. It started as an experiment and turned out to be very effective.

Lots of discussion came from it at the Home Model Engine Machinist Forum (HMEM):

Grinding Cams - Will this Work? - Home Model Engine Machinist

Any further questions and comments are welcome here.

THanks
