Gibs
There are three main gib adjustments for the Model G4003G. They are: the
Cross-slide Gib, see Figure 52
The gib on the
The gib is wedge shaped and by loosening the screw closest to the operator and then tightening the opposite screw, the slide will become looser. Conversely, loosening the screw farthest away from the operator and tightening the closer screw will tighten the gib. Do not over tighten.
Adjust the gib so that it creates a slight drag when the slide is in motion. Test the ease of motion with the gib slightly loose. Begin tightening the gib and test after making small adjustments. When a slight drag is detected the gib is properly adjusted.
NOTICE
When adjusting gibs, keep in mind that the goal of gib adjustment is to remove unnec- essary sloppiness from the slide movement without causing them to bind. Loose gibs may cause poor finishes on the workpiece. Over tightening may cause premature wear.
