(% DISCONNECT POWER TO THE LATHE!
)% Using the chuck key, open each jaw so the workpiece
will lay flat against the chuck face.
*% Support the workpiece.
+% Lock the tailstock, then turn the tailstock quill so
the dead center makes contact or is close to the
center point of your workpiece (see
=`^li\()).
,% Turn each jaw until it just makes contact with the
workpiece.
-% In an opposite pattern, tighten each jaw in small
increments. After you have adjusted the first jaw,
continue tightening the opposing jaw. Frequently
check the dead center alignment to make sure you
have not wandered off your index point due to
applying too much pressure to a single jaw.
.% 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.
/% Make fine adjustments by slightly loosening one jaw
and tightening the opposing jaw until the workpiece
is precisely aligned. Use a dial indicator to fine tune
adjustments into alignment (see
=`^li\(*).
=`^li\(*% Exact centering procedure
with a typical 4-jaw chuck using a dial
indicator.
=`^li\()% Rough centering procedure
with a typical 4-jaw chuck, using the dead
center and the tailstock.
