Cross Slide & Compound Rest Gibs

The gibs for the cross slide and compound rest are flat bars that are held between the component and the dovetail way by the gib screws (see Figures 90–91).

Adjust these gib screws in the same manner as the carriage gib screws.

Adjusting Drive Belts

Drive belts stretch and wear with use, so check the tension on a regular basis to ensure optimal power transmission. Replace the belts if they show signs of glazing, fraying, or cracking.
