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
1
⁄
2
the distance of the amount of
taper (see
Figure 47
).
9.
Repeat
Steps 6–8
until the desired accuracy
is achieved.
Move the tailstock toward
the
front
of the lathe ½ the
distance of the taper.
Looking down from above.

— If the test stock is
thinner
at the tailstock
end, move the tailstock toward the
back
of
the lathe
1
⁄
2
the distance of the amount of
taper (see
Figure 48
).
Move tailstock toward the
back
of the lathe ½ the
distance of the taper.
Looking down from above.

Centers
Figure 49
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.
