Gib Adjustment
the goal of adjusting the cross slide gib is to
remove sloppiness or free-play from the ways
without making the cross slide overly stiff and dif-
ficult to move.
in general, loose gibs cause poor finishes and
tool chatter. over-tightened gibs cause premature
wear and make the handwheel difficult to turn.

When you are satisfied with the gib adjust-
ment, keep the set screws from moving and
re-tighten the hex nuts to secure the settings.

necessary, repeat Steps 2–4.
