Removing Center from Spindle
To remove the sleeve and center from the spindle,
insert a piece of round bar stock (or similar)
through the outside end of the spindle. Have
another person hold onto the sleeve and center
with a gloved hand or shop rag, then tap the bar
stock to knock the sleeve loose.
Mounting Center in Tailstock
Either a carbide-tipped dead center or live center
can be used in the tailstock. Mounting instructions
are the same for both.
Figure 46 shows an exam-
ple photo of a dead center mounted in a tailstock.
3. Use quill handwheel to feed quill out from
casting approximately 1".
Note:
The maximum quill travel is 3
3
⁄
4
", but
we do not recommend extending the quill
more than 2" or stability and accuracy will be
reduced.
4. Insert center into tailstock quill.
5. Seat center firmly into quill during workpiece
installation by rotating quill handwheel clock-
wise to apply pressure with center engaged
in center hole in workpiece.
Note:
Only apply enough pressure with the
tailstock quill to securely mount the workpiece
between centers. Avoid overtightening the
center against the workpiece, or it may
become difficult to remove later, and it will
result in excessive friction and heat, which
may damage the workpiece and center.

dead center installed in the tailstock.

Removing Center from Tailstock
To remove the center from the quill, hold onto it
with a gloved hand or shop rag, then rotate the
quill handwheel counterclockwise to draw the quill
back into the casting until the center releases.
If the center does not come loose by retracting
the quill, extend the quill to expose the slot shown
in
Figure 47, then use a drift key to remove the
center.
To mount a center in the tailstock:
1. DISCONNECT MACHINE FROM POWER!
2. Thoroughly clean and dry tapered mating
surfaces of tailstock quill bore and center,
making sure that no lint or oil remains on
tapers.
To avoid premature wear of the dead center
or damage to the workpiece, use low spindle
speeds and keep the tip of the dead center
mounted in the tailstock well lubricated.
