2. Rotate rest to desired angle, as indicated by
scale at base, then re-tighten (2) 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.
The compound rest handwheel has an indirect-
read graduated scale. This means if you move the
cutter in 0.001" you will have removed 0.002" of
material from the diameter of your workpiece. The
base of the compound rest has another graduated
scale used for setting the cutting tool to a specific
angle, up to 60° left or right.

To set compound rest at a certain angle:
1. Loosen (2) hex nuts at base of compound
rest (see
Figure 54).

Compound Rest
Tool Post
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").
Tool holders can be quickly loaded and unloaded
using the lock lever. Tools up to
5
⁄
8
" can be
secured by tightening the tool holder set screws.
The thumb wheel rotates to adjust cutting tool
height. The tool post is rotated by loosening the
top nut.

To install a tool in tool post:
1. Position tool in holder so cutting edge extends
just enough to allow tool to cut freely—but
no more. Cutting edge must be well sup-
ported to ensure good cutting results and
avoid chipping.
