G0492 12" X 36" Combo Lathe/Mill
The dead center is used in the tailstock and lathe
spindle to support workpieces. When used in
the tailstock, make sure to keep the MT#3 dead
center tip and workpiece lubricated to prevent tip
galling.
This lathe/mill is also supplied with an MT#5 dead
center that fits into the lathe spindle taper.
To install a dead or live center:
1. Feed the quill out about 1" and insert the
MT#3 dead center ( Figure 24). The mating
tapers provide the locking action.

NOTICE
Failure to keep dead center point well
lubricated will gall the dead center and
workpiece.
Using the Centers
To install the MT#5 dead center in the spin-
dle:
1. DISCONNECT POWER TO THE LATHE/
MILL!
2. Remove the chuck from the spindle.
3. Install the MT#5 dead center in the spindle.
4. Attach the faceplate to the spindle, see

Note: When using the dead center in the
spindle, use a lathe dog so that your part will
rotate with the spindle and not spin on the
dead center tip.
