If necessary in the following step, refer

to Offsetting Tailstock on Page 44 for
detailed instructions.

8.

Use calipers to measure both ends of the

workpiece.

— If the test stock is thicker at the tailstock

end, move the tailstock toward the front of
the lathe

Steps 6–8 until the desired accuracy

is achieved.

Move the tailstock toward

the front of the lathe ½ the

distance of the taper.

Centers

Figure 50 shows the MT#5 dead centers
included with the lathe. In addition, an MT#7–
MT#5 tapered spindle sleeve is included for
mounting centers in the spindle.

Dead Centers

A dead center is a one-piece center that does not
rotate with the workpiece and is used to support
long, slender workpieces

Use the dead center in the spindle for operations
where the workpiece rotates with the center and
does not generate friction.

The carbide-tipped dead center can better
withstand the effects of friction and is best
used in the tailstock where the workpiece will
rotate against it. The tip of the center must be
generously lubricated during the operation to
avoid premature wear and maximize smooth
operation. Using low spindle speeds will also
reduce the heat and wear from friction.
