tailstock setup

the tailstock alignment was set at the factory with
the headstock. however, we recommend that you
take the time to ensure that the tailstock is aligned
to your own desired tolerances.
to align the tailstock:
1.
Center drill a 6'' long piece of bar stock on
both ends. set it aside for use in step 4.
2. Make a dead center by turning a shoulder
to make a shank. flip the piece over in the
chuck and turn a 60° point (see figure 13).
As long as it remains in the chuck, the point
of your center will be accurate to the spindle
axis.
note: Keep in mind that the point will have
to be refinished whenever it is removed and
returned to the chuck.
