feed Direction

Never move selection levers while machine is

the selection knob as shown in figure 14.

When the selection knob is positioned as depict-
ed in figure 14, the apron will move to the right
along the bed or the cross feed will travel away
from the operator. the cross feed and longitudinal
feed selection is controlled on the apron and will
be discussed later.
to reverse the direction of the feeding or thread-
ing operation, rotate the selection knob to the
right. it should be noted that when the lever is
positioned in the middle, no direction is selected
and all of the drive mechanisms after this point
are in neutral.
important:
do not force any selection 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 gears and the
selector will engage.

Quick change
Selection
the two levers at the bottom of the headstock
change the feed rate, or the number of threads-
per-inch. this section of the machine is common-
ly known as the Quick Change gear Box. see
figure 16. the left-hand lever can be engaged in
any of five different positions and are listed on the
charts as A, B, C, d, and e. the right-hand lever
has 8 positions and are listed on the charts as 1
through 8.
the machine label describes some of the more
typical settings which might be used. figure 17
shows the feed rate chart located on the gear
cover of the lathe. the chart is divided into metric
feed rates and inch feed rates.
