Gibs - Woodstock Shop Fox M1112 Owner's Manual

NOTICE
When adjusting gibs, keep in mind that the goal of
gib adjustment is to remove unnecessary sloppiness
from the slide movement without causing them to
bind. Loose gibs may cause poor finishes on the
workpiece. Over-tightening may cause premature
wear.
There are three areas with gib adjustments on the Model
M1112: the cross-slide gib, the compound slide gib, and the
saddle gib.
Cross Slide Gib
The gib on the cross-slide (Figure 60) is adjusted by the
two screws located at each end. To adjust, loosen the
set screw located along the edge of the cross-slide. This
set screw is provided for locking the slide for certain
operations. After making the adjustments detailed below,
tighten the set screw until it just touches the gib.
The gib is wedge shaped and by loosening the screw
closest to the operator and then tightening the opposite
screw, the slide will become looser. Conversely, loosening
the screw farthest away from the operator and tightening
the closer screw will tighten the gib. Do not over tighten.
Move the cross slide and adjust the gib until you feel a
slight drag.
Compound Gib
The compound gib (Figure 61) is adjusted by the same
method as the gibs on the cross-slide, except the screw
closest to the operator (when the compound slide is
aligned with the cross slide) must be loosened and the
screw farthest from the operator tightened to make the
gib tighter.
