Remove the saw guards and the saw blade,
then loosen the carriage and headstock locks.
Move the headstock and carriage all the way
to the right and lock them in place.

Mount the drill chuck on the spindle, as
shown in Figure B-113. Completely close
the chuck jaws, as in Figure B-114.

Mount the cup center into the tailstock's
adjustable center, as seen in Figure B-115,
then mount the tailstock into the base mount
(right side). Tighten the mount lock.
88.
Loosen the quill lock. Extend the quill (seen
in Figure B-116), so the drill chuck almost
touches the cup center point and the center
point could fit into the chuck jaws.
89.
If the center point does not "fit" into the
chuck jaws, determine whether you need to
adjust the cup center point horizontally and/
or vertically. Then do the following:
a.

loosen the tailstock stop collars. Raise
or lower the tailstock in the base mount

lines up with the drill chuck, then
tighten the mount lock. Press the stop
collars down firmly against the base
mount and tighten the collar set screws,
as shown in Figure B-118.
