The workman has only to put on the
rough fly wheel, adjust the first set of
tools' push the lever, and let the ma
chine do the rest.
The cast iron Is peeled off as readily
as wax. Sometimes four or five opera

set of cuttings is done, the machine
stops automatically, and the next set

of metal are removed from the wheel.

The vertical cutter of gears on fly

MOVING up and down, the cutter at
the same time slowly revolves, the fly

Whole forests of lumber were being
turned into bodies in the wood work
department. This lumber comes in by
carloads. AS PA feet of wood Is re-

readily seen why so much was re-
quired.
You make this round and you can
understand this company's immense
consumption or materials - is, 000 900
pounds of solder annually, $500, 900
pounds or tin and lead for smoldering,
IO,00O,O0O pounds of brass and copper.
100000 feet of steel tubing and 125, :
900 tons of steel.
BUT what Impressed the dealers moro
than all was the department in which
materials are tested. They insist I'M
on knowing thing is right before it
goes into Willys-Overland car.
Tests in the physical and chemical
laboratories are made in two ways.
competed steel parts are subjected to
terrific tests. Axles are twisted like
rolls of taffy candy. Small bits of
steel, six inches long, cut from COM
pleted aXles, are attached at both ends.
and literally pulled apart. The regis
tering machine shows 200, 900 pounds to
the square inch necessary to accom-
plish this, whereas resistance up to
$4,000 pounds would be proof of am
pie tensile strength. Springs are tried
for their resistance.
Steel articles are also put through
both heat and chemical tests. The
former determines the amount of car
bon, an important factor; the other de-
termines the chemical composition of
the steel.
Naturally every operation In all the
plants tends finally toward the assem-

Top quality of workmanship is as
sured by having each man do work on
which he is an expert, if 1t be only to
tighten a bolt.
Lines of motors, already tested, wait
on both sides of the conveyor. These
are put into place, cantilever springs
are put on, steering mechanism and
lighting and starting system are ad-
justed. Gradually the car takes form. |
