Compound Rest Gib
Figure 145 shows the gib location on the com-
pound rest. The compound rest gib adjusts in
the same manner and with the same tools as the
cross slide gib. However, in this case, to increase
or decrease tension, the gib adjustment screw
directions are reversed.

Saddle Gib
The saddle is supplied with a carriage lock on the
front right-hand side of the slide (see Figure 146).
This bolt locks the saddle in place for increased
rigidity when making face cuts. Before making
adjustments to the saddle gib, make sure that this
lock is loose by turning it counterclockwise one
full turn.
IMPORTANT: Do not loosen the carriage lock
more than a couple of turns or the components
inside will come apart. Re-installing these compo-
nents is difficult and time consuming.

The saddle gib is located on the bottom of the
back edge of the slide (see Figure 147). This gib
is designed differently than the cross or compound
slide gibs. Instead of being a wedge-shaped plate,
it is a flat bar. The gib pressure is applied by four
set screws. Hex nuts secure these set screws in
place, so they will not loosen during operation.

If carriage lock (see Figure 146) is tight,
loosen it two turns.
Loosen jam nuts on four set screws shown
in Figure 147, and adjust set screws same
amount as follows:
—To tighten carriage gib, tighten set screws.
—To loosen gib, loosen set screws.
Repeat adjustments as necessary until
adjustment is acceptable.
Hold set screws in place and tighten jam
