I've built something a bit like this, but it clamps to the QUILL,
not to the spindle. Once it is mounted and the socket screws are
clamped, it will hold position very tightly until I remove it.

I have seen some similar ideas for making a spindle-powered high
speed adaptor that is either parallel (like ours) or coaxial to the
main spindle. They use a belt drive to power the aux spindle at
a higher speed than the main. If you use two belts, and have a bearing
set that runs the high speed spindle coaxially in the arbor that fits
into the main spindle, then the two spindles have the same XY position.
