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. The
Figure below
shows
an example photo of a dead center mounted in a
tailstock.

Carbide-Tipped
Dead Center
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.
To mount a center in the tailstock:
1.
DISCONNECT LATHE FROM POWER!
2.
Thoroughly clean and dry the tapered mating
surfaces of the tailstock quill bore and the
center, making sure that no lint or oil remains
on the tapers.
1. DISCONNECT LATHE FROM POWER!
2.
Thoroughly clean and dry all threads and
mating surfaces of the spindle bore
and the
center, making sure that no lint or oil remains
on these surfaces.
Note: This will prevent the tapered surfaces
from seizing due to operational pressures,
which could make it very difficult to remove
the center.
3.
Mount the chuck, faceplate, or drive plate
onto the spindle, whichever is correct for your
operation.
4.
Insert the center into the spindle bore through
the chuck, faceplate, or drive plate.
The
Figure below shows an example photo
of a dead center installed in the spindle, using
a lathe dog and faceplate for turning between
centers.

Live Centers
A live center (not included) has bearings that
allow the center
tip and the workpiece to rotate
together; it can be
installed in the tailstock quill for
higher speeds.
