Aligning Tailstock - Grizzly G0516 Owner's Manual

Aligning Tailstock

The tailstock on the Model G0516 is aligned
with the headstock at the factory. However, at
times you may wish to misalign the tailstock for
certain operations; then, realign it when you are
finished.
To align the tailstock:
1. Center drill a 6'' long piece of round cold
rolled stock on both ends. Set it aside for use
in step 4.
2.
Make a dead center by turning a shoulder to
make a shank, then flip the piece over in the
chuck and turn a 60° point. See Figure 69.
Note—As long as it remains in the chuck, the
point of your center will be accurate to your
spindle axis. Keep in mind that the point will
have to be refinished whenever it is removed
and returned to the chuck.

4.
Attach a lathe dog to the bar stock and mount
it between the centers. See Figure 70.
5.
Turn approximately .010" off of the diam-
eter.

NOTICE
Before making adjustments to the tailstock,
mount a dial indictor so that the dial plung-
er is on the tailstock barrel. See Figure 71.

6.
Measure the workpiece with a micrometer.
If the stock is fat at the tailstock end, the
tailstock needs to be moved toward you
the amount of the taper. See Figure 71. If
the stock is thinner at the tailstock end, the
tailstock needs to be moved away from the
operator by at least half the amount of the
taper. See Figure 72.
