Gibs

There are four gib adjustments for the Model
G0516—the cross-slide gib, the compound slide
gib, the apron gib, and the mill/drill downfeed gib.
NOTICE
When adjusting gibs, keep in mind that the
goal of gib adjustment is to remove unneces-
sary sloppiness without causing the slides to
bind. Loose gibs may cause poor finishes on
the workpiece and may cause undue wear on
the slide. Over-tightening may cause prema-
ture wear on the slide, leadscrew and nut.
Cross-slide Gib—The gib on the cross-slide is
adjusted by tightening or loosening the 4 gib
screws located on the right-hand side of the slide.
See Figure 65. Before adjusting the gib screws,
loosen their jam nuts.
Figure 65. Cross slide gib screws.
The gib is held in place by the setscrews. DO
NOT overtighten. The gib is properly adjusted
when a slight drag is detected while turning the
hand crank. This drag should be evenly distrib-
uted among the 4 setscrews, so adjust each
screw until a slight drag is detected while the
hand crank is turned.
