thr split nut ideas are great if you have little wear and want to lessen the
slack, however, if you have more wear in one part of the screw than the
other, this is likely to bind when you get out of this sweet spot...

just a thought.

Similar to an earlier suggestion, but slightly different: split the nut,
so it is like a pair of jam nuts, and then turn one half so the slop is
taken out. Then, cross drill and pin, or silver solder, or come up with
some other method of holding them.
