OK, the grinder is working. My first use was to grind some 120 degree "flats" on the larger drill shanks. For drills 1/2" and over the flats are nice to have. I had a bit of a learning curve, you cannot grind too much at one time! I set the work-head with an indicator to move at a perfect 90 degree angle with respect to the face of the cup wheel.
I also marked the three index positions with a permanent marker pen. Put the drill in the proper collet and set the grind to very light. Here is 9/16" drill that I put flats on. I could not do this without a lot of fuss on the mill.
