5. secure the workpiece with a minimum of
three independent clamping devices (see
figure 31). Failure to follow this step may
lead to deadly injury to yourself or bystand-

clamping to the faceplate.

centers
the Model g9036 lathe is supplied with two Mt#3
dead centers and a Mt#5-Mt#3 adapter sleeve to
fit Mt#3 centers into the spindle.
Matching tapers in the spindle or tailstock quill
provide the locking action. Before installing any
center or arbor, make sure that the mating surfac-
es are perfectly clean. these parts will last longer
and remain accurate if properly maintained. if oil
is present on the mating surfaces, the tapers will
not interlock.
Most often, a dead center or live center is used in
the tailstock to support workpieces. dead centers
do not spin during use and the tip must be con-
stantly lubricated.
NOTICE
failure to keep a dead center tip well lubricat-
ed will damage dead center and workpiece.

spin during use, so they do not need lubrication
during operation. When using a live center, the
tailstock barrel should protrude at least
