This is an essential adjustment that should be 
verified or performed each time the tailstock 
is used to turn concentric workpieces between 
centers or immediately after offsetting the 
tailstock when turning a taper. If the tailstock is 
not aligned with the spindle centerline when it is 
supposed to be, turning results will be inaccurate 
along the length of the workpiece.

  Use the precision level to make sure the 

bedway is level from side-to-side and from 
front-to-back.

— If the bedway is not level, correct 

this condition before continuing with 
this procedure (refer to Leveling & 
Mounting on Page 28).

  Center drill both ends of one piece of round 

stock, then set it aside for use in Step 5.

  Use the other piece of round stock to make 

a dead center, and turn it to a 60° point, as 
illustrated in Figure 45.

 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.

  Install a center in the tailstock.

  Attach a lathe dog to the test stock from 

Step 2, then mount it between the centers 
(see Figure 46 for an example).

  Turn 0.010" off the stock diameter.

 

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