Alan, I put 360 to 1 in for belt reduction and 72 threads per inch
and the result was .0125 inches per step. That is a pretty clean
calculation for a rotary and I'll probably let it go at that. Does
that sound reasonable?

The free step calculator has been revised and moved to:

I believe the copy-paste problem (that Larry mentioned) has been
fixed. A gear rack, teeth per inch calculation for the rack and
pinion was added.
