While that is true, my thinking is that if i gear it up so that 1700
RPM -> 2000 spindle RPM then I lose mre torque at low speeds through
the
gearring. On the o

Now I am ready to figure out what to do for the spindle drive.

More obviously, run the motor at its rated speed, change one of the pulleys

Now I am ready to figure out what to do for the spindle drive.
The project is a 1972 Clausig NC lathe. The original paper tape fed
controls are long gone. I actually have the owners manual. The original
lathe had a 5 HP motor and a variable speed transmission similar to
bridgeport heads and many m
