I think you got it right, with one caveat: Abom79 was power
reversing the spindle

Yes, that is the plan, anyway. ?
Are you saying you can just disengage the
half nut, hand crank the carriage back, and
restart on the same number?

I had that idea a while ago as I had some
parts to make that would have been easier to
leave in the chuck and go back and forth to
the lathe and mill. I considered using
carbide tooling to thread a commercial hex
block as there was sufficient wall thickness
for the threads. I never got around to it
but it is still in the back of my mind. If I
had a surface grinder making one would be
much easier. I have a 10k and have used the
printed gears from Ebay with great success
making metric threads. I believe I saw a way
to use the threading dial on you tube but
never tried it. Something about using the
same mark on the dial I believe but don't
hold me to it.
