Compound Slide Gib; Saddle Gib - Grizzly G0776 Owner's Manual

Compound Slide Gib

Figure 132 shows the gib arrangement for the
compound slide. The compound slide 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
133). This lock secures the saddle 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.

Carriage Lock
The saddle gib is located on the bottom of the
back edge of the slide (Figure 134). 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.
