G0554 Gear-Head Floor Lathe
Centers
The dead center is used in the tailstock to support
workpieces. When used in the tailstock, make
sure to keep the dead center tip and workpiece
lubricated.
The Model G0554 lathe is supplied with two
MT#3 dead centers–one is HSS and one is car-
b
ide tipped. The supplied MT#5-#3 sleeve fits
into the spindle taper to hold the MT#3 center.
To install a dead or live center:
1. Feed the quill out about 1" so that the dead
center
can be inserted.
2. Insert the dead center
into the quill opening.
Matching tapers provide the locking action
(see Figure 39).

NOTICE
Failure to keep dead center point well
lubricated will damage dead center and
workpiece.
The dead center can also be used in the spindle.
The most common application is when using the
faceplate (see Figure 40).
To install the dead center in the spindle:
1. Remove the chuck from the spindle.
2. Install the dead center in
the spindle sleeve.
3. Install the sleeve
and center into the spindle
opening.
4. Attach the faceplate to the spindle.
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.
3. Move the tailstock into position and lock in
place.
4. Feed the quill into the workpiece.
Note: Make
sure there is a center drilled hole
in the end of workpiece for the dead center.
5. Lock
the quill into place once the live center
and the part rotate together. The
quill may
need to be adjusted during
operation.
6. To remove the dead center, retract the quill
until
the dead center pops free.
