FEED SELECTION
Never move the feed rate lever while the machine is running.
The Model B Lathe / Mill has 2 feed control levers which must be engaged in order to use the powerfeed
or threading feature. The
Feed Rate Lever,
shown in
Figure 19,
controls internal gears that change the
feed rate by a factor of 2. Turning the lever to position “l” will cause the
Lead Screw
to turn at twice the
rate as when it is in position “ll”. When this lever is straight up, the gearing is in neutral and no power
feed is available.
Figure 19.

Important
Do not force any lever on the machine. If the lever will not engage, rotate the chuck
by hand
while
keeping light pressure on the selector. As the chuck rotates it aligns the gear teeth inside the selector box
and the selector will engage.

FEED LEVER
While the
Lead Screw
can be placed in neutral with the feed selection lever, another lever allows the
power feeding feature of the lathe to be turned on and off. When turned to the left, as in
Figure 20,
the
Feed Lever
connects power to the apron. When turned to the right, the apron cane be fed manually and
the hand crank no longer turns by itself. The apron cannot be moved manually unless the
Feed Rate Lever
is in neutral or the
Feed Lever
is turned to the right. Please see the caution below.
