G0657/G0658 Benchtop Lathe
Faceplate turning ( Figure 38) is when a workpiece
is mounted to the faceplate, which is mounted to
the headstock spindle. This type of turning is usu-
ally done with open-faced workpieces like bowls.
If screws cannot be placed in the workpiece, then
a backing block can be glued to the workpiece
and attached to the faceplate with screws.
Figure 38. Typical faceplate turning operation.
To mount your workpiece to the faceplate:
1. Find the center of your workpiece in the same
manner as when spindle turning.
2. Cut off the corners of the workpiece.
3. Center the faceplate on the workpiece and
attach it through the faceplate holes with
non-tapered head wood screws as shown in
Figure 39.
4. Thread the faceplate onto the headstock
spindle and tighten securely.
Faceplate Turning
• Turn the lathe OFF immediately if the
workpiece vibrates excessively. Check to
make sure the workpiece is centered and
balanced. Remove the workpiece and trim
excess waste off corners with a bandsaw or
table saw to reduce vibration. Make sure the
workpiece is securely attached in the setup.
9. Position the tool rest approximately 1 ⁄
4
" away
from the workpiece and approximately 1 ⁄
8
"
above the center line, as shown in Figure
37.
10. Test the setup by hand-turning the workpiece
to make sure there is enough clearance all
the way around before starting.
Spindle Turning Tips:
• When turning the lathe ON, stand to the side
of the spinning direction until the lathe reach-
es full speed and you can verify that the lathe
will not throw the workpiece.
• Use the slowest spindle speed when rough
cutting.
• Select the right speed for the size of workpiece
you are turning. Use slower speeds for
large workpieces (4" diameter and over); use
the middle range speeds for medium sized
workpieces (2" to 4" diameter); and use faster
speeds for small sized workpieces (under 2"
in diameter).
• Make sure the turning tool is against the tool
rest the ENTIRE time that the turning tool is
in contact with the workpiece.
• Learn the correct techniques for each tool
you will use. If you are unsure, read books or
magazines about lathe techniques and seek
training from experienced users.
