In the beginning...
For
their time,
Geo. Stevens
coil winders
were some of
the best
available
anywhere.
They were used
to make radio
and TV
electronic
tuning coils
(inductors),
and Gibson
and other
instrument
makers also
used Stevens
winders to
wind their
pickup coils.
Here is a
1950's ad
showing their
possibilities.

I
bought these
two
George Stevens
electronics
coil winders
years ago on
Ebay.
When
I bought them
I had an interest in
antique pinball machines, and
needed a machine
to rewind solenoid coils for them. I
had no idea
I was missing too many parts
to restore them as they were.

The big one on its own board
is a 1954?
Stevens 120M gang winder
originally factory set up to
wind four pinball machine
solenoids at once.
If you look
closely, the coil arbor is
still mounted in the machine
with some
partially
wound pinball
solenoids on it!

The small one by itself is my
1940's Model 20 winder.
It was basically stripped for
parts to keep the 120M running
over the years.
Today, I am studying
electromechanical engineering
at my local technical college,
where I learned about robotics
and the Arduino microcomputer.
I decided that since the
missing parts
for my winders were impossible
to find, I would use my own
Arduino and a servomotor to
convert
my Model 20 into a modern CNC
controlled pickup winding
robot. After all, if some of
my
classmates could design
'battlebots' using them
I could use the same tech to
make my pickups.

Looks
hopeless... doesn't it?
It's
not.
The castings are all
there, the shafts are
good, it still has its
original
wire feeder
(hanging
down on the traverse
feed rod),
and best of all,
the 'clock' wire
turns counter
actually still
works! I will
have to make
some parts,
but there's a
lot of
potential
here.
