What is the proper technique for using an edgefinder in a vertical milling
machine?

Bring the finder in to contact the edge.

Wind in the slide until the finder runs true,
by eye.

Continue winding in until the 0.200 projection
moves to an offset postion and stops running true.
At the instant it does, your spindle axis is
0.1 inch from the edge.

Just creep up on it, and keep re-zeroing
the dial or DRO until the edge finder
snaps off-center.
