-24- G4002/3 Gear Head Lathes
Saddle Gib - The saddle is supplied with a
square head bolt on the front right hand side of
the slide. Before making adjustments to the sad-
dle gib, ensure that this bolt is loose by turning it
counter clockwise. See Figure 26b.
It is important that the apron gib be properly
adjusted. A loose gib will cause finish problems
in a workpiece. A gib adjusted too tightly will
cause premature wear.
The gib for the saddle is located on the bottom
of the back edge of the slide. The tension on this
gib is maintained by four setscrews with jam
nuts. By loosening the jam nuts and tightening
the setscrews, the gib will tighten. Loosening the
setscrews will loosen the gib. The gib strip is
properly adjusted when a slight drag is detected
while moving the apron. Do not over tighten.
It is important the 4 setscrews are tightened
evenly. When tightening the jam nuts, hold the
setscrew’s position using an Allen
®
wrench.

Steady/Follow Rest
To adjust the Steady Rest:
1. Loosen the lock nuts. See Figure 27.
2. Open the sliding fingers by turning the
knurled screws until they fit around the
workpiece. Secure the steady rest in posi-
tion.
3. Tighten the knurled screws so that the fin-
gers are snug, but not tight against the
workpiece. Tighten the setscrews and the
lock nuts.
4. Lubricate the brass points with machine oil.
The Follow Rest is setup in the same manner
except that the place of the third finger is taken up
by the tool bit. The follow rest prevents long,
small diameter pieces from flexing under the cut-
ting pressure from the tool bit.
