I am making the AB leadscrew ends for a friend's machine. He went
thru a Dremel a month before Wal-Mart refused to keep replacing them.

He bought the Mini-Mill head and is putting a treadmill motor on it.
with 3 step pulleys, he can go from half speed (3,000 RPM) to double
speed (12,000 RPM) and with the speed controller, have some
flexability. Those are no-load rpms, still not operational, so we
don't know the final speeds.
