Aligning Tailstock - Grizzly G0600 Manual Insert

Aligning Tailstock

To align the tailstock:
1. Using a precision level, make sure the
bedways are level side-to-side and front-to-
back. If the lathe is not level, shim the lathe
base as required before proceeding.
2.
Get two pieces of steel round stock that are
2" diameter x 6" inches long.
3.
Center drill both ends of one piece of the
round stock. Set the round stock 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 (Figure 26).
Note: As long as the dead center remains in
the chuck, the point of your center will remain
true to the spindle axis. But remember the
point will have to be refinished whenever it is
removed and returned to the chuck.

5. Place the live center in the tailstock.
6. Attach a lathe dog to the round stock and
mount it between the centers.
7. Turn approximately 0.010" off the diameter.
8. Mount a dial indicator so the plunger is on the
tailstock barrel before moving the tailstock.
9. Measure the stock diameter with a microm-
eter.
— If the diameter is thicker at the tailstock
end, move the tailstock toward you half of
the diameter (Figures 27).
— If the diameter is thinner at the tailstock
end, move the tailstock away from you half
the distance of the diameter (Figure 28).

10. Turn another 0.010" off of the diameter and
check for a taper. Repeat until the desired
amount of accuracy is achieved.
