Aligning
The offset of your lathe was aligned with the spindle centerline at the factory. We recommend that you take the time to ensure that the tailstock is aligned to your own desired tolerances, especially if you have changed the offset to cut shallow tapers.
To align the tailstock offset to the spindle centerline:
1.Use a precision level to make sure the bedway is level from
—If the bedway is not level, correct this condition before continuing with this procedure.
2.Obtain two pieces of steel round stock 2" in diameter and 6" long.
3.Center drill both ends of one piece of round stock, then set it aside for use in Step 6.
4.Use the other piece of round stock to make a dead center, and turn it to a 60° point, as shown in Figure 68.
Figure 68. Non tapered dead center in the chuck.
Note: As long as this dead center remains in the chuck, the point of the center will remain true to the spindle centerline. The point will have to be refinished whenever the center is removed and then returned to the chuck.
5.Install a center in the tailstock.
6.Attach a lathe dog to the piece of stock from Step 3, then mount it between the centers, as shown in Figure 69.

the centers.
7.Turn 0.010" off the diameter of the stock.
8.Mount a test or dial indicator so that the plunger is on the tailstock quill.
Note: If necessary in the following step, refer to "To Set Up the Tailstock to Cut a Shallow Taper" on Page 42 for adjusting the tailstock offset.
