Steady Rest - Grizzly G9972Z Owner's Manual

Mounting Workpiece Between
Centers
1.
DISCONNECT LATHE FROM POWER!
2.
Drill center holes in both ends of the workpiece.
3.
Install a dead center in the spindle with a
lathe dog and a chuck or faceplate, then
install a live center or carbide-tipped dead
center in the tailstock.
4.
Lubricate the workpiece center holes, then
mount the workpiece between the centers
and hold it in place with light pressure from
the tailstock center.
5.
Seat the center firmly into the quill by rotating
the quill handwheel clockwise to apply pres-
sure against the workpiece (see the example
in Figure 39).
Note: Only apply enough pressure to secure-
ly mount the workpiece between centers.
Avoid over-tightening the center against the
workpiece, or it may become difficult to
remove later. Also, over-tightening will result
in excessive friction and heat, which may
damage the workpiece or center.

mounted between the centers.
6.
Secure the quill lock lever and tailstock lock
nut.

To install and use the steady rest:
1. DISCONNECT LATHE FROM POWER!
2.
Thoroughly clean all mating surfaces, then
place the steady rest base on the bedways
so the triangular notch fits over the bedway
prism.
3.
Loosen the finger lock nuts shown in
Figure 40, turn the finger adjustment knobs,
and adjust the fingers as required for the
workpiece.
4.
Loosen the steady rest lock nut, position the
steady rest where required to properly sup-
port the workpiece, then secure the lock nut.
5. Turn the finger adjustment knobs so the fin-
gers are barely touching the workpiece, then
tighten the finger lock nuts.
6.
Lubricate the finger tips with an anti-seize
lubricant during operation.
Note: Mill or file the tips if they show wear.
