Figure 7. Tailstock controls.
Y.Quill Handwheel: Moves the quill toward or away from the spindle.
Z.Graduated Scale: Indicates quill movement in increments of 0.001" with one full revolution equaling 0.200" of quill travel.
AA.Tailstock Lock Lever: Secures the tailstock in position along the bedway.
AB. Quill Lock Lever: Secures the quill in position.
AC. Quill: Moves toward and away from the spindle and holds centers and tooling.
AD. Tailstock Offset Screw: Adjusts the tailstock offset left or right from the spindle centerline (1 of 2).
AE. Gib Adjustment Screw: Adjusts the tapered gib to control tailstock offset accuracy
(1 of 2).
AF. Offset Scale: Indicates the relative distance of tailstock offset from the spindle centerline.
End Gears
Configuring the end gears shown in
Figure 8 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 9) 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
