OPERATION
5. Close the steady rest and tighten the lock
knob.
6. Loosen the three leaf screws. Without
causing any deflection in the workpiece, use
the finger adjustment knobs to position the
finger rollers against the workpiece.
7. Tighten the leaf screws.
Note: The finger rollers should properly support
the workpiece but allow it to freely rotate.
Follow Rest
The follow rest mounts to the saddle with two
cap screws (Figure 77). It is used on long,
slender parts to prevent workpiece flexing from
the pressure of the cutting tool during operation.
Adjust the fingers on the follow rest in the same
manner as those on the steady rest. To avoid
marring, make sure to keep the contact surface
well oiled during turning operations.
2. Rotate the compound slide to the desired
angle, as indicated by the scale at the base,
then retighten the two hex nuts.
Tip: If setting up to cut external right-hand inch
or metric threads, or left-hand internal
threads for the first time, set the compound
so its travel is perfectly parallel with the
cross slide. Using a protractor, rotate the
compound 29.5° counterclockwise and mark
the new location on the compound slide. This
mark will be the quick reference point for
setting the offset angle. To mark for internal
right-hand threads, or left-hand external
threads, repeat this process, but rotate the
compound 29.5° clockwise and mark the
cross slide accordingly.

Hex Nut
Compound
Slide
The compound slide handwheel has an indirect-
read graduated collar. This means that the
distance shown on the scale represents the
actual distance the tool moves, which will remove
twice as much material from the diameter of the
workpiece. The base of the compound slide has
another graduated collar used for setting the tool
to a specific angle.
To set the compound slide at a certain angle:
1. Loosen the two hex nuts at the base of the
compound slide (1 of 2 shown in Figure 78).
