Hmm, that's right. You'd need some sort of feedback (DRO?) to do the
mapping, wooncha?

Yeah, and the new lathe doesn't come with a DRO, which would run me roughly
$700. I'll bet I can wheedle someone qualified to do it for half that.

The question, then, is would precision, pre-machined-ends screws cost me in
differential cost even less than that. I'm betting yes, but haven't nailed
it down. The precision-ground screw crowd doesn't seem to list their
prices on-line (which could be BADDD!G)
