2.Center drill both ends of one piece of round stock, then set it aside for use in Step 5.

3.Use the other piece of round stock to make a dead center, and turn it to a 60° point, as illustrated in Figure 30.

Figure 30. Turning a dead center.

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.

4.Install centers in the spindle and tailstock.

5.Attach a lathe dog to the test stock from Step 2, then mount it between the centers (see Figure 31 for an example photo).

6.Turn 0.010" off the stock diameter.

7.Mount a dial indicator so that the plunger is on the tailstock quill.

8.Use calipers to measure both ends of the workpiece.

—If the test stock is thicker at the tailstock end, move the tailstock top casting toward the front of the lathe 1⁄2 the distance of the amount of taper (see Figure 32).

Move the tailstock toward

the front of the lathe ½ the

distance of the taper.

—If the test stock is thinner at the tailstock end, move the tailstock top casting toward the back of the lathe 1⁄2 the distance of the amount of taper (see Figure 33).
