Faceplate
Refer to the Chuck Installation (Page 25)
and Chuck Removal (Page 27) instructions to
install or remove the faceplate.
The optional Model SB1469 cast-iron faceplate
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.
Only machine a non-concentric workpiece
at low speeds and clamp counter-weights to
the faceplate to balance it. Machining a non-
concentric workpiece at a high speed could
cause it to be thrown from the spindle with
deadly force at the operator or bystanders.
Use a minimum of THREE independent
clamping devices to hold the workpiece onto
the faceplate. Failure to properly secure a
workpiece to the faceplate could cause it to be
thrown from the lathe with deadly force at the
operator or bystanders.
To mount a non-concentric workpiece to the
faceplate:
1. DISCONNECT LATHE FROM POWER!
2. Place a sturdy piece of plywood under the
spindle to protect the bed ways during the
installation process.
3. Position the workpiece onto the faceplate
and clamp it in place with a minimum of
three independent clamping devices (see
Figure 25 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.
