Faceplate

Refer to the prior Chuck Installation and Chuck
Removal subsections 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 workpiece to be
thrown from lathe with deadly force. To
reduce this risk, use a low RPM, and use
counter-weights to balance faceplate or
workpiece.
Failure to properly secure workpiece to
faceplate could cause workpiece to be
thrown from lathe with deadly force. To
reduce this risk, use a minimum of THREE
independent clamping devices to hold
workpiece onto faceplate.
