G0492 12" X 36" Combo Lathe/Mill
To setup the tailstock to cut tapers:
1.
Lock the tailstock in position.
2.
Alternately loosen and tighten the left and right
offset adjustment screws until the desired off-
set is indicated on the scale (see
Figures 19
& 20 ).
3. Retighten the lock screw.
Note: To return the tailstock back to the
original position, repeat the process until the
centered position is indicated on the scale.
The tailstock is aligned at the factory with the
headstock. We recommend that you take the
time to ensure that the tailstock is aligned to
your own desired tolerances.
To align the tailstock:
1. Using a precision level on the bedways,
make sure the lathe/mill is level side-to-side
and front-to-back. If the lathe/mill is not level,
correct this condition before proceeding.
2.
Get two pieces of steel round stock, two
inches in diameter and six inches long.
3. Center drill both ends of one piece of the
round stock. Set it 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 (see
Figure 21 ) .
Note: As long as the dead center remains in
the chuck, the point of your center will remain
true to the spindle axis. Keep in mind that the
point will have to be refinished whenever it is
removed and returned to the chuck.
