Tailstock

The tailstock on the Model G4002/3 is aligned at
the factory with the headstock. It is recommend-
ed that you take the time to ensure that the tail-
stock is aligned to your own desired tolerances.
To align the tailstock:
1. Center drill a 6'' long piece of bar 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. Flip the piece over in the
chuck and turn a 60° point. See Figure 28.
As long as it remains in the chuck, the point
of your center will be accurate to your spin-
dle's axis. Keep in mind that the point will
have to be refinished whenever it is
removed and returned to the chuck.

3. Place the live center in your tailstock.
4. Attach a lathe dog to the bar stock and
mount it between the centers. See Figure
29.
5. Turn approximately .010" off the diameter.

TIP
Before making adjustments to the tailstock,
mount a dial indicator so that the dial's plunger
is on the tailstock barrel. See Figure 30.

6. Measure the stock 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 30.
