Spindle Spider

spindle supports otherwise known as a "spider"
(see Figure 58).

Remove spider screws when not in use.
Always DISCONNECT LATHE FROM POWER
when installing, removing, or adjusting spi-
der screws. Ignoring this warning can lead
to personal injury or machine damage.
The spider is especially designed for supporting
gun barrels during chambering operations; how-
ever, it is a great support option for almost any
long workpiece that extends through the outboard
side of the spindle.
The tips of the spider screws have brass wear
pads that hold the workpiece without causing
indents in the finish.
When spider screws are installed, always use the
jam nuts to lock each spider screw in position.
Merely tightening the spider screws against the
workpiece and leaving the jam nuts loose is not
safe. Spiders screws that loosen during operation
can crash into the lathe end cover.

Manual Feed

The cutting tool can be manually fed into the
workpiece using the carriage, cross slide, and
compound rest handwheels shown below.

Carriage Handwheel
The carriage handwheel moves the carriage left
or right along the bed. It has a graduated dial with
0.01" increments. One full revolution moves the
carriage 1.2".
Cross Slide Handwheel
The cross slide handwheel moves the tool to-
ward and away from the work. Adjust the position
of the graduated scale by loosening the thumb
knob, holding the handwheel with one hand and
turning the dial with the other, then tightening the
thumb knob. The cross slide handwheel has a
direct-read graduated dial, which shows the total
amount of material removed from the diameter of
the workpiece. The dial has 0.002" increments,
and one full revolution moves the slide 0.2". Ro-
tate the dial collar 180° to read in metric units.
Cross Slide Handwheel
The compound rest handwheel moves the cutting
tool linearly along the set angle of the compound
rest. Adjust the position of the graduated scale in
a similar manner with handwheel and dial. The
compound rest angle is set by hand-rotating it
and securing in place with four hex nuts. The
compound rest has an indirect-read graduated
dial with 0.001" (0.025mm) increments. One full
revolution of the handwheel moves the slide 0.1".
