Follow Rest
The follow rest mounts to the saddle with two cap screws (see Figure 57). It is used on long, slender parts to prevent workpiece deflection from the pressure of the cutting tool during operation. Adjust the follow rest fingers in the same manner as the those on the steady rest.
Note: To reduce the effects of friction, lubricate the brass finger tips with generous lubricant during operation.
Compound Rest
The compound rest handwheel has an indirect- read graduated scale. This means that the distance shown on the scale represents the actual distance the cutting tool moves. The base of the compound rest has another graduated scale used for setting the cutting tool to a specific angle.

Carriage & Compound Rest Locks
The carriage and compound rest have locks that can be tightened to provide additional rigidity during operation, especially during heavy cuts.
See Figure 58 to identify the locations of the locks for each device.

To set the compound rest at a certain angle:
1.Loosen the two acorn nuts at the base of the compound rest (1 of 2 shown in Figure 59).

2.Rotate the rest to the desired angle, as indicated by the scale at the base, then retighten the two acorn nuts.
Tip: The first time you set the angle of the compound rest for cutting threads, mark the location on the cross slide as a quick reference point. This will allow you to quickly return the compound rest to that
