Improperly supported or positioned cutting
tools can "catch" on workpiece, ejecting
tool from your hands with great force. To
reduce this risk, always ensure tool rest is
properly positioned for each type of opera-
tion, cutting tool is firmly supported against
tool rest BEFORE cutting, and cutting tool
is properly positioned to cut at the correct
angle for tool and operation type.
The tool rest assembly consists of two compo-
nents: the tool rest base (or banjo) and the tool
rest. The tool rest base moves forward/backward
and along the length of the lathe bed. The tool
rest rotates and moves up and down in the tool
rest base. Locks for both components allow you to
secure the tool rest in position after making these
adjustments.
When adjusting the tool rest, position it as close
as possible to the workpiece without actually
touching it. This maximizes support where the
cutting occurs and minimizes leverage, reducing
the risk of injury if a "catch" occurs. Adjust the
tool rest as necessary during operations when the
workpiece diameter decreases.
Many woodturners typically set the height of the
tool rest
1
⁄
8
" above or below the centerline of the
workpiece, depending on their height, the type
of tool they're using, and the type of operation
they're performing.
As a rule of thumb: For most (spindle) turning
operations, the cutting tool should contact the
workpiece slightly above centerline. For most
inside (bowl) turning operations, the cutting tool
should contact the workpiece slightly below
centerline.
Keeping all these factors in mind, your main goal
when adjusting the tool rest should be providing
maximum support for the type of tool being used,
in a position that is safe and comfortable for you.
Always operate lathe with tool rest assem-
bly firmly locked in position. Otherwise,
serious personal injury may occur by tool
being pulled from operator's hands.

Adjusting Tool Rest
To adjust tool rest:
1. Loosen tool rest base lock lever and move
tool rest assembly to desired position on
lathe bed, as shown in
Figure 13.
Note: To maximize support, the tool rest
base should always be locked on both sides
of the bed. Never pull the tool rest so far back
that it is only secured on one side.
2. Retighten tool rest base lock lever to secure
tool rest assembly in position.
Note: The clamping hex nut underneath the
tool rest base will require occasional adjust-
ing to ensure proper clamping pressure of
the tool rest assembly to the bed. Turn this
hex nut in small increments to fine tune the
clamping pressure as needed.
3. Loosen tool rest lock handle (see Figure 13).
4. Position tool rest in desired location.
5. Retighten tool rest lock handle to secure tool
rest in position.
