Carriage
A. Steady Rest: Provides support for long, slen-
der stock and can be positioned anywhere on
the bedway.
B. Follow Rest: Follows the movement of the
carriage and provides support for long, slen-

ing due to cutting tool pressure.
C. 4-Way Tool Post: Holds four different cut-
ting tools that can be indexed (rotated) to the
workpiece as needed.
D. Compound Slide Handwheel: Moves the
compound slide and mounted tooling toward
or away from the workpiece at the angle
selected.
E. Compound Slide Angle Scale: Displays the
angle of the compound slide and mounted
tooling in relation to the spindle center line.

leadscrew, shows when to engage the half-
nut during certain inch threading operations.
G. Half-Nut Lever: Opens and closes the half-

the longitudinal leadscrew for non-threading
powered carriage movement.
I. Carriage Handwheel: Moves the carriage
and the mounted tooling left-or-right along
the bedway.
J. Cross Slide Handwheel: Moves the cross
slide and mounted tooling in-or-out to the
bedway.
Tailstock
A. Quill: Holds a tapered center or tool, and
moves toward or away from the spindle with
the use of the handwheel.
B. Quill Lock: Locks the quill and installed tool
in place.
C. Quill Handwheel: Moves the quill in and out
of the tailstock casting.
D. Offset Scale: Indicates the tailstock offset
from the lathe center line.
E. Tailstock Lock Nut: Secures the tailstock in
place on the bedway.
NOTICE
Engaging the feed lever and the half-nut
at the same time will damage the car-
riage gearing and longitudinal leadscrew.
NEVER attempt to force the feed lever in the
engaged (up) position and half-nut lever in
the engaged (down) position at the same
time.
