4-Jaw chuck
Always use a low spindle speed when
machining non-concentric workpieces or
for off-center turning to avoid ejecting the
workpiece from the mounting device at
a high rate of speed. Failure to heed this
warning could lead to serious personal
injury, death or property damage.
the 8" 4-jaw, direct mount, independent chuck
included with your lathe has hardened steel
jaws that are independently adjusted and can be
independently reversed, which allows for a wide
range of mounting versatility for non-concentric
workpieces.

lay a piece of plywood on the bedway under
the chuck to protect it.
3.

workpiece will lay flat against the chuck face
or jaw steps.

With assistance or a supporting device,
mount the workpiece centered on the chuck,
then turn each jaw until it makes contact with
the workpiece.

tighten each jaw in small increments. After
you have adjusted the first jaw, continue tight-

After the workpiece is held in place by the
jaws, turn the chuck by hand and notice the
workpiece alignment.

— if the workpiece is not correctly aligned for
your operation as you turn the chuck, make
fine adjustments by slightly loosening one
jaw and tightening the opposing jaw until
the workpiece is correctly aligned (see
Figure 33 for an example).
