Faceplate
Refer to Chuck & Faceplate Mounting
instructions on Page 27 to mount the faceplate
to the spindle.
The 12" faceplate included with your lathe offers
a wide range of uses, 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.
Mounting Workpiece with Clamps
1. DISCONNECT LATHE FROM POWER!
2. Place a piece of 3 ⁄
4
" plywood on the bedway
below the spindle.
3. With help from another person, place the
workpiece onto the faceplate and clamp it in
place with a minimum of three independent
clamping devices (see Figure 63 for an
example).
Note: Be sure to take into account the rotation
and cutting forces that will be applied to the
workpiece when clamping it to the faceplate.
4. Double check tool and slide motion
clearances before turning spindle ON.
Mounting Workpiece Between
Centers
1. DISCONNECT LATHE FROM POWER!
2. Drill center holes in both ends of the
workpiece.
3. Install the dead center in the spindle and the
live center or carbide-tipped dead center in
the tailstock (refer to Page 37).
4. Secure a lathe dog on the spindle-end and
place a drop of oil in the center hole on the
tailstock-end of the workpiece.
5. Mount the workpiece between centers so the
lathe dog tail fits freely in the faceplate slot
without binding.
Failure to properly secure a workpiece to the
faceplate could cause the workpiece to be
thrown from the lathe with deadly force at the
operator or bystanders. Use a minimum of
three independent clamping devices to hold a
non-concentric workpiece onto the faceplate.
Machining non-concentric workpieces at a
high speed could cause the workpiece to be
thrown from the spindle with deadly force at
the operator or bystanders. To reduce this
risk, only machine non-concentric workpieces
at low speeds and clamp counter-weights to
the faceplate to balance it.
