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
