Aligning Tailstock

The tailstock is aligned at the factory 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:

1.Using a precision level on the bedways, make sure the lathe/mill is level side-to-side and front-to-back. If the lathe/mill is not level, correct this condition before proceeding.

2.Get two pieces of steel round stock, two inches in diameter and six inches long.

3.Center drill both ends of one piece of the round stock. Set it aside for use in Step 6.

4.Using the other piece of stock, make a dead center by turning a shoulder to make a shank. Flip the piece over in the chuck and turn a 60º point (see Figure 21).

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.
