End Gears

Configuring the end gears shown in
Figure 7 will control the speed of the leadscrew
for threading or the feed rod for power feed
operations. The rotational speed of these
components depends not only on the end gear
configuration, but the spindle speed as well.

Safety Foot Brake

This lathe is equipped with a foot brake (see
Figure 8) to quickly stop the spindle instead of
allowing the spindle to coast to a stop on its own.
Pushing the foot brake while the spindle is ON
cuts power to the motor and stops the spindle.
After the foot brake is used, the spindle lever
must be returned to the OFF (middle) position
to reset the spindle switches before re-starting
spindle rotation.
