Gib Adjustments
When adjusting the compound rest, cross slide,
and carriage gib screws (see Figures 77–78), the
goal is to remove looseness in the ways without
causing the slides to bind. Loose gibs will cause a
poor finish on the workpiece, and over-tightening
may cause premature wear on the slide,
leadscrew, and nut.
The compound rest uses a tapered piece of iron
which is held in position by two gib screws at
opposing ends of the gib.

The front and rear gib adjustment screws
are turned in opposite directions from each
other (one screw clockwise and the other
counterclockwise, or visa versa), the single gib
will be pushed fore or aft to fill the loose void in
the way. Thus, the play in the slide is removed. If
more play is needed, adjust the screws so the gib
is moved and held in the opposite direction.
