Typical tailstock tapered drill bit
installation.
To install the tapered drill chuck:
1.
With the tailstock locked, pull up to unlock the
quill lock lever.
2. Turn the quill feed handle clockwise to extend
the quill about one inch.
3.
Insert a tapered drill arbor (
Figure 29
), or the
tapered drill shank ( Figure 30 ), into the quill
until the taper is firmly seated. The matching
tapers hold the arbor.
4.
Turn the quill feed handle clockwise to feed
the drill bit into the rotating workpiece.
5. To remove the chuck taper, turn the quill feed
handle counterclockwise until the chuck is
pushed out from the tailstock taper.
Cutting Tapers with
Tailstock
The tailstock can be offset to cut a taper.
To offset the tailstock:
1.
Lock the tailstock in position, and loosen the
jack screw located just above the adjustment
screw (
Figures 31
and
32
).
2.
When the offset is achieved, snug the jack
screw that you have been turning counter-
clockwise, and then snug opposite jack-
screw.
