3.Center drill both ends of one piece of the round stock and set it aside for use in

Step 6.

Note: If the tailstock is slightly out of align- ment by a few thousands of an inch, the center drill will find the center point during the drilling process. If the tailstock appears grossly out of alignment, move the tailstock until it appears to be near or at center (refer to Cutting Tapers Using the Tailstock on Page 28).

4.Using the other piece of round stock, make a dead center by turning a shoulder to make a shank, then flip the piece over in the chuck and turn a 60° point (see Figure 36 for an example).

Note: As long as the fabricated dead center remains in the chuck, the point of your center will remain true to the spindle axis or center line. Keep in mind that the point will have to be refinished whenever it is removed and re- installed in the chuck.

5.Place the live center in the tailstock.

6.Attach a lathe dog to the bar stock from Step 3 and mount it between the centers (see

Figure 37).

7.Turn approximately 0.010" off the diameter.

8.Mount a dial indicator so the dial plunger is on the tailstock barrel before making adjust- ments.

9.Measure the stock with a micrometer.

—If the stock is fatter at the tailstock end, move the tailstock toward the operator half the distance of the amount of taper (see

Figure 38).
