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 34. If the
stock is thinner at the tailstock end, the tail-
stock needs to be moved away from the
operator by at least the amount of the taper.
See Figure 35.
NOTICE
Before making adjustments to the tailstock,
mount a dial indictor so that the dial plunger is
on the tailstock barrel. See Figure 34.
