Depends on your leadscrew pitch and the size of your stepper and the
size of the machine.
Which machine are you putting it on?
I would suggest you put the banjo back on the lathe and take a look at
that end.
This gives you a mount area for the stepper and an existing spindle on
which to mount a pulley

I was wondering about speed reduction from using pulleys.
Would mounting direct to lead screw work? Might take some ugly
mounting jig.

This was my approach.I bought a surplus South Bend 10L lead screw
holder and milled some of it away so I could fit an extension to
hold the pulley.
Then cast a couple of brackets and set them at right angles to
hold the motor nicely out of the way.
The belt takes care of any alignment issues.I'm going to try the
400W Bergerda AC servo and I'll just have to change the one
bracket and maybe get or make a pulley with the correct bore
size.With the AC servo that has a max RPM of 3000 I think I'll
stay with 2:1 reduction.I'll still end up with 4x the current speed.

Craftsman 12x36 lathe.
The motors fit an angle NEMA 23 stand or I could make up something.
Any ideas?
Appreciate any help.
