End Gears

Gears

Figure 7. End gear components.

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.

Foot Brake

Figure 8. Foot brake and spindle lever.

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.
