I like all the ideas and suggestions here. Many thanks to all who responded.
I think I'll try these automotive gear tooth sensors, and see how that works, Digikey.ca has them available, so I can order them fairly locally. Just FYI, I do like the Acetal nut idea, will try that before going ball-screw; the leadscrew on this lathe is pretty clean, and I do have a brand new cross slide screw. PS - Cecil - glad you can't make any "000" sized screws - they'd be lost in the swarf, at least in my shop! John A. Stewart.
