Mounting Dead Center in Spindle
1.
DISCONNECT MACHINE FROM POWER!
2.
Thoroughly clean and dry all threads and
mating surfaces of spindle bore and 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 chuck or faceplate onto spindle, which-
ever is correct for your operation.
4.
Insert center into tapered spindle sleeve,
then insert center into spindle bore.
The Figure below shows an example photo
of a dead center installed in spindle, using a
lathe dog and faceplate for turning between
centers.

Live Centers
A live center has bearings that allow the center
tip and the workpiece to rotate together; it can be
installed in the tailstock quill for higher speeds.

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.
Figure 50. Example of using a carbide-tipped
dead center installed in the tailstock.
To avoid premature wear of dead center
or damage to workpiece, use low spindle
speeds and keep tip of dead center mounted
in tailstock well lubricated.
To mount a center in tailstock:
1.
DISCONNECT MACHINE FROM POWER!
2. Thoroughly clean and dry tapered mating
surfaces of tailstock quill bore and center,
making sure no lint or oil remains on tapers.
