You don't need a spindle encoder for thread milling. I have
used it VERY rarely, but when you decide to make a
non-standard thread, then it is very handy. I cut some
non-standard internal threads on parts at an angle, and it
made things MUCH easier. Otherwise, I'd have had to mount a
vise, spacer blocks and sine bars on a lathe faceplate,
which sounded like I'd need 5 hands!
So, I put all that on the mill, drilled the starter hole and
then thread milled it. Worked like a champ, although slower
than a lathe would do it.
