Cutting Shallow Tapers
with the Tailstock
To setup the tailstock to cut tapers, do these steps:
1. Lock the tailstock in position.
2. Alternately loosen and tighten the left and right
offset adjustment screws until the desired offset is
indicated on the scale (see
Figures 25 & 26).
3. Retighten the lock screw.
Note: To return the tailstock back to the original
position, repeat the process until the centered posi-
tion is indicated on the scale.

Tailstock Alignment
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, do these steps:
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
27).
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.
