While other thread pitches may be achieved, the Model

M1112 is designed so that gear changes are not needed for

cutting inch threads. However, you will have to move the

feed direction lever to the direction of thread you want

to cut, and then move the feed rod lever to the right. To

get the needed threads in inches, you will then use the

standard thread chart (=`^li\46) to determine which

positions to move the quick change levers.

<oXdgc\1

If the desired threads are 11 threads per inch (=`^li\46),

move the quick change gearbox levers to positions 9 and

,. As the thread dial chart shows, engage the half-nut

when the thread dial reads ( or *and begin your first

cut.

When the cut is complete, disengage the half-nut and

manually return the carriage to the beginning of the cut.

Watch the dial. When the ( or the * on the dial comes

around to the indicator mark, engage the half-nut. Begin

your second pass. Repeat this process until the desired

depth of cut is achieved.

=`^li\46%Standard thread chart.

This lathe can cut 29 different metric threads, but gear

changes are required to cut all of the listed metric

threads. These gear changes take place on the left hand

end of the machine (=`^li\47).

The chart is divided into 3 main columns, starting from

the left: Gear diagram, Combination of Gears and

/m Per

Pitch.
