to prevent the workpiece slipping off the
dead center tip, center drill the tailstock end
of the workpiece with a tapered hole that
matches the tip of the dead center.
seat the center into the quill, position the
tailstock so that the tip of the center presses
against the workpiece enough to hold it in
place, then tighten the tailstock lock lever.
rotate the tailstock handwheel clockwise to
feed the center farther into the workpiece
until it is snug, then tighten the quill lock
Note: Do not overly force the center into
the workpiece with the handwheel—this will
make removing the center very difficult and
could damage it.
to remove the center from the quill, hold
onto it with one hand, then rotate the tailstock
handwheel counterclockwise to draw the quill
back into the casting until the center releas-
the tailstock can be positioned offset from the
spindle center line to cut a taper. When the
tailstock is moved toward the operator from the
center line, the machined end of the workpiece
nearest the tailstock will be smaller in diameter.
Conversely, position the tailstock away from the
operator from the center line to machine a taper
near the spindle.
Note: To return the tailstock to the center position,
perform the Tailstock Alignment procedure on
the next page.

To set up the tailstock to cut a shallow taper:
Alternately loosen and tighten the set screws
on either side of the tailstock until the desired
