Aligning Tailstock
The tailstock is factory aligned with the headstock. We
recommend that you take the time to ensure that the
tailstock is aligned to your own desired tolerances.
To align the tailstock, do these steps:
1. Using a precision level on the bedways, make sure
the bedways are level side-to-side and front-to-back.
If the lathe is not level, correct this condition by
shimming the lathe base before proceeding.
2. Get two pieces of steel round stock that are two
inches in diameter and six inches long.
3. Center drill both ends of one piece of the round
stock. Set the round stock aside for use in Step 6.
4. Using the other piece of stock, make a dead cen-
ter by turning a shoulder to make a shank. Flip the
piece over in the chuck and turn a 60º point (see
Figure 17).
Note: As long as the dead center remains in the
chuck, the point of your center will remain true to
the spindle axis. Keep in mind that the point will
have to be refinished whenever it is removed and
returned to the chuck.
5. Place the live center in the tailstock.
6. Attach a lathe dog to the round stock and mount it
between centers.
7. Turn approximately 0.010" off the diameter.
8. Mount a dial indicator so the dial plunger is on the
tailstock barrel before moving the tailstock.
9. Measure the stock diameter with a micrometer.
— If it is thicker at the tailstock end, move the
tailstock toward you half of the diameter (Figures
18 & 20).
— If it is thinner at the tailstock end, move the
tailstock away from you half the distance of the
diameter (Figure 19 & 20).
10. Turn another 0.010" off of the diameter and check
for a taper. Repeat this process as necessary until
the desired amount of accuracy is achieved.
