On small, low-end mills (Sherline, Taig, ubiquitous mini-mill) most
people keep
the original screws. The backlash on a 16- or 20-TPI screw has to be
pretty small,
anyway.

On larger machines, and with worn 5-TPI Acme screws, it is much better
to upgrade to
ballscrews. That may be the most expensive part of a retrofit, however.

There's no reason you couldn't do your Clausing mill. Obviously, you
will be limited to
the size of that machine's motion.
