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-slideGib—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.
