OPERATION
2. Rotate the compound to the desired angle,
as indicated 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
reference point. This will allow you to
quickly return the compound rest to that
exact angle the next time you need to cut
threads.
Figure 71. Compound slide set at an angle.

Compound
Slide
The compound slide handwheel has an indirect-
read graduated scale. 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 scale 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 71).
Compound Slide
The four-way tool post is mounted on top of the
compound slide and allows a maximum of four
tools to be loaded simultaneously.
The four-way tool post allows for quick indexing
to different tools, which is accomplished by
loosening the top handle, rotating the tool post
to the desired position, then re-tightening the
handle to lock the tool into position.

Tool Post T-Wrench ...............................................1
To load the tool post:
1. Choose the desired cutting tool.
2. Loosen the tool post bolts so that the cutting
tool can fit underneath them.
Note: If necessary, place one steel shim
underneath the cutting tool so the cutting tip
is properly aligned with the workpiece. The
shim should be as long and as wide as the
cutting tool to properly support it.
Four-Way Tool Post
3. Firmly secure the cutting tool with at least
two tool post bolts (Figure 72).

Over-extending a cutting tool from the tool
post will increase the risk of it breaking during
operation, which may cause metal pieces to
be thrown at the operator or bystanders with
great force. Only extend a cutting tool 2.5
times the width of its cross-section or less
(i.e., 2.5 x 0.5" = 1.25").
