I inherited a little 1/4 inch shank brown unknown abrasive grinding wheel from
my father, well worn.

So I trued it.

I placed the drill press base and column on the bench and added the cross vise.
No screws yet. I put the diamond truing tool in the vise, along the steps with
the jaws removed. I added the head, stopped at the top of the column. I added
the wheel, tightening the chuck firmly. I moved the vise to the side and
screwed it two steps off center, then slid the vise over to the right. I
lowered the head to place it near the wheel. I adjusted the cross slide so the
diamond was after top dead center, that is, the closest point, to avoid a
catch. I slid the long feed by hand using the ruler to get a start.

I ran the wheel down along the diamond, removing an excessively heavy cut. I
stopped. The wheel was way out. I got a high spot touch and took a cut. Nice.

What a friggin' mess. I had particles in my hair, on the adjacent table, and
the floor. I probably breathed some. I guarded the cut with my hand and
continued to feed with the long feed. At one point the diamond glowed red.
Oops. C + O2 = C O2. Lost some expensive diamond that way. Eventually I got
that nice crisp sound and gave it up.

Soon I will mount the accessory table to the cross vise, clamp the Unimat
spindle head in the vise, clamp a bicycle crank extractor bolt in the three jaw
chuck, and tilt the table to present the work to the wheel at an angle. Then
I'll take off a little to make the bolt fit the dust cap Harris sold me, to
form a one key extractor with an 8 mm hex key fitting. The work will spin,
driven by the wheel, and stay true. Harris didn't have any extractors so they
sent me parts that were close. They are quite convenient, and are a security
risk for those parking in high risk areas.

Oh, by the way, it looks like smoochie and I are buying a house together. Maybe
out in Sterling near the airport and the bike trail.
