Drilling with
Tailstock
the tailstock can be used to drill holes by mount-
ing a drill bit in the tailstock, rotating the workpiece
with the spindle, then using the tailstock quill
feed handwheel to advance the drill bit into the
workpiece.
To set up the tailstock for drilling:
1. lock the tailstock in position, then unlock the
quill.
2. use the quill feed handwheel to extend the
quill about one inch out of the tailstock.
3. insert the drill chuck arbor into the drill chuck
(see figure 40), then insert the assembly
into the quill until the taper is firmly seated.
the matching tapers hold the arbor.
