TAILSTOCK
The tailstock slides along the bed way freely, and may be used to secure the free end
of a rotating workpiece.
The tailstock is clamped to the bedway using
the Tailstock Clamping Lever (Q).
The Quill (P) can be rotated inward and outward,
using the Tailstock Handwheel (S). The Quill can
be locked in place using the Quill Lock Lever.
The quill is shipped with a “dead end” which may
be inserted into the quill. “Dead end” means
that the end remains stationary, and allows the
workpiece to rotate upon it. To reduce friction,
it is a good idea to apply a little grease to the
contact between the workpiece and the dead
end. Check this lubrication from time to time.
“Live ends” are available to fit this machine and may be
purchased separately. Live ends incorporate a bearing
to reduce friction between the workpiece and the quill.
Before using your lathe, it is important to check the
alignment of the tailstock with the arbor spindle. Do
this by placing a precisely machined rod in the chuck,
and checking its alignment with the center of the quill.
Accurate measurements may be made by mounting
a dial indicator to the bedway, and making measure-
ments on the rod near the headstock, and near the
tailstock. These measurements must be exactly alike
for the tailstock to be properly aligned.
Adjustments may be made by loosening the tailstock
lock lever, then adjusting the position of the tailstock with the alignment screw (512).
Retighten the lock lever, and recheck the alignment before proceeding.
FOLLOW REST AND STEADY REST
These are useful supports for your workpiece, which help
you improve machining accuracy.
The Follow Rest is attached to the Apron, and fol-
lows the movement of the apron as the workpiece is
machined.
The Steady Rest is attached to the bedway, and re-
mains in place as the workpiece turns within it.
Install these rests as needed to support the work-
piece.
Adjust the brass holders within the rests to lightly ride
upon the workpieces. It is advisable to apply a little
grease to the points of the brass holders to reduce
friction between them and the workpiece.
The rests should be cleaned and stored in a dry clean
place when not in use.
