Saddle Gib

The saddle gib is located on the bottom of the back edge of the cross slide (see Figure 132). This gib is designed differently than the cross or compound slide gibs. Instead of being a wedge- shaped plate, it is a flat bar. The gib pressure is applied by four set screws. Hex nuts secure these set screws in place, so they will not loosen during operation.
