After the workpiece is held in place, back the
tailstock away and rotate the chuck by hand.
the center point will move if the workpiece is
out of center (see figure 29).
figure 29. properly held workpiece for low
speed offset boring or machining.
Make fine adjustments by slightly loosening
one jaw and tightening the opposing jaw until
the workpiece is held securely and precisely
aligned with the spindle centerline.
this section outlines basic operation safety relat-
ed to using the faceplate included with your lathe.
use knowledge of safety and common sense
when applying the steps on how to use this face-
plate. if you have any questions, feel free to con-
tact our technical support department.
the faceplate is cast-iron and has multiple slots
for t-bolts that hold clamping hardware. if you
suspect that any of the chuck or jaw combina-
tions may not hold a workpiece safely, remove
the chuck and install the faceplate as outlined for
special clamping options.
However, just as with the 4-Jaw chuck, not
all workpieces can be safely held. Holding a
workpiece off center or holding an irregular-
shaped workpiece will cause the entire assembly
to rotate out of balance. if spun at any speed
higher than low, the workpiece can eject hitting
the lathe operator or bystanders causing a severe
or fatal injury.
figure 30 shows an example of a workpiece being
improperly held with the 4-jaw chuck. one jaw of
the chuck interfered with the workpiece edge, and
removing the jaw creates an extreme workpiece
ejection hazard. the workpiece holding solution
shown in figure 30 is to use the faceplate with
a minimum of three clamps that are spaced as
equally apart as possible for full support.
