The complete drop forging OF tho
front axle can be accomplished with
one heat.
Every kind of part recurring
strength was drop forged while we
looted on, axles, crank shafts, brake
assembly rods. brake and control
rods. spring shackles, gear blanks.
and brake rod sectors.
We saw the company's accurate
system of die making 1t calls for
a special workman on each detail
One works on the shaper, another on
the planer and third on die sink
ing.
A multiple spindle drill in one
operation drills all the holes in the
front axle. This is a guarantee that
each will be in right relation to the
| other.
1t was hard to drag us away from
the automatic turret lathe that sur
faces and finishes fly wheels. 1t
works as though somewhere in its
metal vitals brain was concealed
The workman has only to put on the
rough fly wheel, adjust the first set
of tools, push the lever and let the
machine do the rest.
The cast iron is peeled off as read
lily as wax. Sometimes four or FIVE
operations are performed at once
When one set Of cutting is done. the
machine stops automatically, and the
next set of tools comes automatical-
ly into place. Twenty operations
are performed in fourteen minutes.
26 pounds of metal are removed
from the wheel. One man can watch
three of these machines.
The vertical cutter OF gears on fly
wheels almost matches the turret
lathe in interest.
Moving up and down the cutter at
the same time slowly revolves, the
fly wheel turning in the opposite d.
rection. BY the time a complete
revolution of the fly wheel has been
accomplished. all the gears are cut.
We all fell for the aluminium foun-
dry and for the machines that finish
the aluminium parts.
The multiple spindle drill bores
81 holes In the crank case in one
operation. This is a proof Of the SUI
periority Of machine processes. for
the holes must be in the right re-
lation with each other.
Another machine smooths the sur
faces of the crank cases, finishing
seven in nine minutes.
Diamonds, real diamonds, are con-
sumed with apparently reckless in
difference in the wet grind room.
Placed in small tools they are used
to true the emery wheels on which
are ground the bearing surfaces of
the crank shafts.
They are bought in SIS, 200 lots.
We looked on while 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 required on a
small touring car. we could readily
see why so much was required.
You make this round and you can
understand this company's immense
consumption of material-1S,00 0,-
900 pounds of solder annually, o.
100000 pounds of tin and lead for
smoldering, 100000 pounds OF
brass and copper, 100000 feet of
steel tubing and $4,000 tons of
steel.
But what impressed me more than
all was the department in which
materials are tested. They have to
know a thing is right before 1t goes
into Willys-overland car. That's
how they safeguard the public.
Tests in the physical and chemical
laboratories are made in two ways.
Completed steel parts are subjected
to terrific tests. Axles are twisted
like rolls of taffy candy. Small bits
of steel, six inches long. cut from
completed axles. are attached at
both ends, and literally pulled apart,
The registering machine shows 200,-
600 pounds to the square inch nee
essary to accomplish this, whereas a
resistance up to $4,000 pounds
would be proof of tensile strength.
Springs are tried for their resistance.
steel articles are also put through
both heat and chemical tests. The
