Live center
the live center is used to support stock which
is too long to be supported by the chuck alone.
stock protruding more than three times its diam-
eter should be supported by the live center.
the tailstock barrel and live center have a Morse
taper #3. Before assembling these, insure that the
mating surfaces are “white glove” clean. these
parts will last longer and remain accurate when
properly maintained. Morse tapers will not inter-
lock when oil is present on the mounting surfaces.
insert the end of the live center into the tailstock
bore until it seats. the force of a mounted work-
piece will fully seat the taper.
When using a live center, the tailstock barrel
should protrude about 1⁄2'' and not more than 3''.

Steady Rest
the steady rest supports long, small diameter
stock that otherwise could not be turned. the
steady rest can also replace the tailstock to allow
for cutting tool access at the outboard end of your
workpiece.
To mount the steady rest:
1. secure to bedway from below with the lock-
ing plate.
2. A single hex bolt, along with a nut and wash-
er, is used to hold the steady rest in place.
see
figure 10.
3. the bearing surfaces on the steady rest
should receive periodic lubrication while in
use to prevent premature wear.
to remove the live center, back the tailstock barrel
all the way into the tailstock casting. the live cen-
ter will pop out. Be sure to catch it when it comes
out to avoid damaging the tip.
