I just realized that since the taped hole in the vice would not
benefit from teh slice and clamp along the axis of the thread, it
could work on a line perpendicular to the axis.

One would still slice the casting somewhere so that the cut is about
1/2 to 3/4 thru the nut section, then, another cut on one of the
connecting legs. This would have the effect of the nuts, one after
the other, connected where there was no saw cut, and one of those
being split.

Threading the two towgether with a single bolt would allow one to
twist to create tention. or to remove the backlash. The BIG risk is
breaking the casting.... been there, done that !

On my HF vice, the taped hole is really sloppy !

A word of caution and a question.

Using some home brew epoxy to create nuts has the risk of really
locking up the screw.

Any ideas what is used or can be used as a home-brew release agent ?
