The tailstock quill and included dead center have MT#3
tapers.
The dead center supports stock that is too long to be sup-
ported by the chuck alone. Stock protruding more than
2
1
⁄2 times its diameter should be supported by a dead or
live center.
If you use a live center, the tailstock quill should protrude
about
1
⁄2'' and not more than 1
1
⁄4'' out of the tailstock body.
(Follow dead center installation/removal instructions when
using live centers.)

(% Make sure the mating surfaces of the dead center
taper and tailstock quill are completely free of dirt
and oil.
Efk\1 When properly cleaned before assembly, these
parts will last longer and remain more accurate over
time. Also, Morse tapers will not interlock properly
when dirt or oil are present on the mounting surfac-
es.
)% Insert the end of the center into the tailstock bore.
*% Fully seat the center by tightening it against a
mounted workpiece with the tailstock handwheel, as
shown in =`^li\**.
Efk\1When using dead centers, always keep them
well lubricated and only use them at low speeds.

(% Move the tailstock away from the mounted
workpiece.
)% Hold the dead center in your left hand, and with your
right hand, turn the handwheel to back the tailstock
quill all the way into the tailstock casting, forcing it
to pop out.

=`^li\**% A dead center installed in the
tailstock and supporting a workpiece.
A workpiece not supported properly
could bend suddenly and be thrown,
causing serious personal injury. Always
use a center to support the end of any
workpiece that protrudes out of the
chuck more than 2
1
⁄2 times its own
diameter.
