Re: lead-screw vs common threaded rod

Jack,

I may have mis read your post.

If you are moving a table for milling, etching, or a router,
(routering?) then my post makes some sence.

if you are talking about clamping for holding fences setting stops
etc, then by all means, home depot and save the cash. for accuracy
in placing a stop, precision ground or rollled all-thread would allow
a nut to turn real nice, but not add accuracy. A 1/2-13 hex nut will
have 6 flats, and for one inch, you would pass 78 flats. each one
being roughly equalivent to 0.013" your 1/128 is about .007 inch.
so if you counted the points between the flats, you could get that
accuracy.
