TAILSTOCK:
The tailstock assembly
shown

requires a minimum of service but the No. 2
Morse

checked
periodically
to insure
it is
free
of
nicks
and
rust. The
quill
should
be removed and
the tapered
socket and outside diameter wiped
once a
month with
light
machine oil. The
tailstock screw
and
thrust
bearing
should
be
coated with
Fiske
Lubriplate 6304 or equivalent.
