Nice breakdown!

Backlash is an absolute fact of life, the only way to eliminate it would be to use an NC type ballscrew, and that would quadruple the price (at least).

.004" backlash is VERY respectable, I deal with machines with an average of .050" and some nearly .1", the older, the worse.

I agree with your gripe about the .062"/turn, that really should be .050, the standard for larger equipment is normally .1"/turn.

I would work around that by doing your layout & setup according to the .062", kind of a pain but you're stuck with that....

You'll have no lack of uses for it, congrats on the purchase.
