TAILSTOCK
The tailstock on any lathe is primarily a work
supporti ng device but it may be used to perform
ot her important functions such as drilling,
reaming and tapping.
Tails tock handwh eel (A), Figure 9, is used to
tra ver se or feed spindle (B) in or out. To per-
mit ac cura te dr i lling to depth spindle (B) is
gradua t ed in inches . Tang slot (C) facilitates
the remo v al of drills and reamers from the tap-
er center hole. To remove the center, crank
th e spind le back into the tailstock until the c en -
ter is automaticall y ejected.
Pulli ng lever ( D) in a clockwise direction locks
the spindle in position . This should always be
done before the start of the cut. (E) is a clamp-
ing lever which quickly clamps the tailstock to
the bed for su ch operations as drilling and
reaming . It is a feature found on all Monarch
Series 61 Toolmaker's Lathes but not on Ser i es
61 Engine Lathes .
On 16" machines clamping lever (E) is supple-
mented by clamping nut ( F) which should be
tightened when turning work between centers or
in any case when there is a considerable amount
of pressure against the tailstock. On 20" mach-
ines there is an additional clamping nut on top
of the tailstock . Ser i es 61 16" and 20" Engine
Lathe tailstocks , while not provided with quick-
clamping lever (E), have double the number of
clamping nuts.
Aligning stud (G) is used to bring the tailstock
to true center with the headstock. On machines
not equipped with a taper turning attachment, it
is sometimes utilized to move the tailstock off
center for taper turning. There are two of these
studs , the other being at the rear of the tail-
stock. Tailstock pickup bushing (H) is engaged
by a plunger on the right hand carriage wing for ·
positioning the tailstock along the bed by means
of the power rapid traverse.
