That's the usual way to do this trick with a brass nut. The part after that
goes: Take a _tapered_ screw, and grind the end off until only one turn will
fit into the tapped hole, and tighten it in until the backlash goes away. The
problem is that this can loosten up frequently, requireing frequent re-
adjustment.

It seems to me, that making a pair of nuts with a large tab sticking out to the
side on each of them would be a better way to go. Drill a hole parallel to the
axis in each tab, for a small bolt. Tightening the bolt, and lock nutting it
in place, would be a much more stable way of making this trick work.
