Model G0740 (Mfg. Since 11/12) -7-
Tailstock End Gears
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 revolu-
tion equaling 0.100" of quill travel.
AA. Tailstock Lock Lever: secures the tailstock
in position along the bedway.
Ab. Quill Lock Lever: secures the quill in posi-
tion.
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.

this lathe is equipped with a foot brake (see
figure 8) to qui ckly 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.
Configuring the end gears shown in figure 7 will
control the speed of the leadscrew for threading
or the feed rod for power feed o perations. the
rotational speed of these components depends
not only on the end gear configuration, but the
spindle speed as well.
