tool rest
test by hand-turning the workpiece before turning
the lathe on. ensure that the lathe chisel is fully
supported by the tool rest. support the lathe chisel
on the tool rest with one hand, while the other
hand controls the chisel. see

Faceplate turning ( figure 17) 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 17. typical faceplate turning operation.
faceplate turning
the contact area between the workpiece
and the faceplate must be flush with one
another. failure to do this could result in
the faceplate distorting or breaking, causing
injury or death.
the joints of glued-up workpieces should be
high quality to prevent them from breaking
under the extreme forces of lathe turning.
consult in-depth trade manuals and instruc-
tional books for correct techniques when
gluing up a workpiece from multiple pieces.
if a joint fails during a lathe turning opera-
tion, serious injury or death could occur.
