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-
bide 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).
