Compound Rest

The compound rest handwheel has an indirect-
read graduated scale. This means that the dis-
tance 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.

To set the compound rest at a certain angle:
1. Loosen the two hex nuts at the base of the
compound rest (1 of 2 shown in Figure 57).

2. Rotate the rest to the desired angle, as indi-
cated by the scale at the base, then retighten
the two hex 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 refer-
ence point. This will allow you to quickly
return the compound rest to that exact angle
the next time you need to cut threads.

Installing Tool

Tool Needed

Hex Wrench Size ......................................... 5mm
To install a tool in the tool post:
1. Position the tool in the holder so the cutting
edge extends just enough to allow the tool
to cut freely—but no more. The cutting edge
must be well supported to ensure good cut-
ting results and avoid chipping.
Over-extending a cutting tool from the post
will increase risk of tool chatter, breakage,
or tool loosening during operation, which
could cause metal pieces to be thrown at
the operator or bystanders with great force.
DO NOT extend a cutting tool more than 2.5
times the width of its cross-section (e.g.,
2.5 x 0.5" = 1.25").
