Adjusting Gibs

there are two gib adjustments for the Model
g8688—the cross-slide gib and the compound
slide gib. the apron gib has been adjusted at the
factory and should need no further attention. See
figure 37 for location.

NOTICE

when adjusting gibs, keep in mind that

the goal of gib adjustment is to remove

unnecessary movement from the slides

without causing them to bind. Loose gibs

may cause poor finishes on the workpiece

and undue wear on the slide, nut and lead

screw. Over tightening will make turning

the handwheel difficult.
