Feed Clutch Knob:
Adjusts how easily the
feed clutch will disengage the feed rod in
order to prevent overload when the carriage
contacts a feed stop, micro carriage stop, or
in the event of a crash. Tightening this knob
(see Figure 47) completely disables this cone-
type clutch. A shear pin that may or may not
break before damage occurs.
Note:
The feed clutch setting will depend on
variables of the longitudinal or cross feed cutting
operations, such as depth of cut, feed rate,
workpiece material, and other considerations.
Finding the ideal clutch setting is a matter of
trial-and-error, and experience.
To Adjust Feed Clutch:
1.
Turn lathe OFF and engage apron power
feed lever
(see
Figure
46)
for your feed
operation.
2.
Pull feed clutch knob outward and rotate it
clockwise through the clicks until tight.
3.
Pull feed clutch knob outward, loosen three
full turns, then release the knob.
4.
Disengage apron power feed leve
r; clutch
tension is now adjusted to a conservative
setting.
Note:
As needed during feeding operations,
fine tune the adjustment to establish
consistent feeding without disengagement,
while still providing overload protection.

Feed Selector Knob:
Selects
the
carriage or
cross slide for power feed operations and quick
traverse operations (see
Figure
46).
Pay attention to your selected lever
combinations. Depending on the combined
configuration of the feed direction lever on
the headstock and the Feed Direction knob
and lever on the apron, the actual direction of
power feed will respectively change from the
printed indicators on the machine!
Note:
When the knob is pulled out, the cross slide
is selected, and when the knob is pushed in, the
carriage is selected.
Note:
When using this control, you may need
to rock the handwheel of the component being
engaged so that the apron gears will mesh.
Apron Power Feed Lever:
Changes power
feed direction (see
Figure
46). This lever
quickly switches the power feed axis between
longitudinal and cross feed operations.
