I had an idea on how to get around the problem of drunken threads - a
spherical-seat washer, which would allow the wheel to be clamped
uniformly despite the cockeyed nuts.

Thew was not space for a fill 5/8" spherical washer set, so I machined a
shallow conical seat into the existing flange washers by setting the
compound at 14 degrees and advancing by moving the tool slide. The 14
degrees comes from a drawing in the MSC catalog on the washers (MSC
#82429366 for instance).

This greatly reduced the vibration, but did not eliminate it. The
wheels still wobble visibly.

I knew there was a reason to have a lathe.

now, just take an old diamond blade, or a dressing tool and dress the sides
of the wheels to remove the wobble and you are done

I'd been thinking of doing that. But first, drag the grinder outside,
so the cloud of abrasive dust doesn't end up coating everything in the
shop.
