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:

2.
Rotate rest to desired angle, as indicated by
scale at base, then retighten two cap screws.
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.

To install tool in tool post:
1.
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").

Position tool in holder so cutting edge extends
just enough to allow tool to cut freely—but no
more. The cutting edge must be well sup-
ported to ensure good cutting results and
avoid chipping.
Secure tool with at least two set screws.
Adjust cutting tool height to spindle center-
line, as instructed in next subsection.
