8.2 Tool support
An 8-inch toolrest is provided with your Lathe. It
allows adjustment for height, position on the bed,
and angle to the work.
Loosen locking handle (E, Figure 8-1) to slide
support base forward or back, and angle it to the
bed. Tighten locking handle securely before
operating Lathe.
Loosen small handle (F, Figure 8-1). Make sure
clamp bushings (inset, Figure 8-1) are spread apart
sufficiently to accept tool support post.
Adjust height of tool support and angle it to the work.
Tighten handle (F) before operating Lathe.
NOTE: Locking handle (F) and clamp bushings can
be removed from hole and inserted from opposite
side for convenience.
8.3 Cam tightness
If headstock, tailstock or tool rest base does not
properly tighten down against bed when locking
handle is tightened, adjust as follows. Figure 8-3
uses tailstock as example.
1.
Unscrew and remove stud, and slide tailstock
off end of bed.
2.
Turn tailstock on its side, and tighten lock nut
with a wrench. See Figure 8-3.
3.
Mount tailstock on bed and test the adjustment.
When adjustments are complete, re-insert stud
at end of bed.
8.4 Locking handles
Locking handles, such as C and F, Figure 8-1, can
be rotated to more convenient position. Lift up on
handle, rotate it on pin, then release it, making sure
it seats on pin.

8.5 Indexer
The indexer has 24 evenly spaced holes concentric
to the spindle, and is used to create evenly spaced
features in a workpiece, while keeping the lathe
spindle locked; for example, when cutting flutes on
a spindle blank with a router, while the spindle blank
is secured between lathe centers. Numbers 1
through 24 are inscribed on top sheave (K, Figure
8-4) for reference. When lathe is powered, however,
the LED display can be used for rapid locating of
index positions, as follows.
1.
Connect lathe to power source.
2.
Push index button (G, Figure 8-4). The LED
display will change from RPM setting to index
setting.
3.
Use handwheel (H) to rotate workpiece to
desired position.
4.
Push in index pin (J, Figure 8-4) and rotate
workpiece slightly until pin engages hole. Then
screw index pin (J) further into headstock to
lock spindle.
5.
Cut first flute in workpiece.
6.
Push index button (G) to set engaged index
position at zero.
7.
Unscrew index pin (J) to release spindle, then
rotate workpiece until next desired hole shows
on readout.
8.
Engage index pin, and rout second flute.
Continue the process.
Example: If 6 evenly-spaced flutes are needed
around full workpiece circumference, use
positions 0, 8, 16, 24, 32, and 40.
IMPORTANT: When finished indexing, unscrew
and release index pin before turning on spindle.
The LED display will revert to RPM setting when
lathe spindle is turned on.

8.6 Centers: installing/removing
8.6.1 Headstock spur center
1.
To install the spur center, the spur center
should first be mounted to your workpiece; see
sect. 10.3 for details). Clean tapered end of
center and inside of headstock spindle, then
push center into spindle.
