The centre position carefully marked. The follower is simply clamped to the faceplate, and placed to match the tailstock centre. (ideally should be be checked with a dial gauge that centre is on follower centre line but I did not bother)
A rod of desired radius in chuck serves to establish the stop for feed. The grinding wheel can be at any height and need not be precisely square, or with good bearings! I originally used a B and D drill sparked out. On another occasion used a small bench grinder mounted as a toolpost grinder. Faceplate just rocked back and forth by hand.
A piece of large round with a trench milled exactly across the centre line and held in a 3j chuck would make for quick mounting.
Have to be careful with the hand oilstone as removes considerable material.
The camshaft is slightly more difficult but not much.
