faceplate

refer to the prior chuck installation and chuck
Removal sections for instructions on installing or
removing the faceplate.
the faceplate included with your lathe can be
used for a wide range of operations, including
machining non-concentric workpieces, straight
turning between centers, off-center turning, and
boring.
the tools needed for mounting a workpiece will
vary depending on the type of setup you have.
Machining non-concentric workpieces at
high speeds could cause the workpiece to
be thrown from the lathe with deadly force.
To reduce this risk, do not exceed 395 RpM,
and use counter-weights to balance the
faceplate or workpiece.

failure to properly secure a workpiece to
the faceplate could cause the workpiece
to be thrown from the lathe with deadly
force. To reduce this risk, use a minimum
of THREE independent clamping devices to
hold the workpiece onto the faceplate.
To mount a non-concentric workpiece to the
faceplate:
1. disCoNNECt lathE FroM poWEr!
2. protect the bedway with a piece of plywood.
3. With help from another person or a holding
device to support the workpiece, position it
onto the faceplate and clamp it in place with
a minimum of three independent clamping
devices (see figure below for an example).
Be sure to take into account the rotational
and cutting forces that will be applied to the
workpiece when clamping it to the faceplate.
if necessary, use counter-weights to balance
the assembly and use a dial indicator to make
sure that the workpiece is properly positioned
for your operation.
