Alas, it is not good practice to dismiss an observation so fast. It is not too thin to do many things. I just find it a little odd to laminate two pieces when using one thicker piece would have sufficed.

Maybe there are two iron rings hidden inbetween two wooden halves and then laminated? Any way, dielectric substances can hold a lot of charge on their surfaces: this is what can be also important. Especially dielectrics composed of layers (or two halves as in this example).

think what is probable

those rings are 1/4" thick, max, and could be as thin as 3/16"

if one tries to router out a channel for some wire, the thing is going to break, or at the very best become quite weak and prone to breaking and flexing.

so with an apparent lamination, it looks like thin plywood. it's not metal, and there's probably no wires hidden within. let's use the razor and move forward

Thanks for the quick reply.   In pat 381,970   Tesla says this

In the present application
my object is to describe the best and
most convenient manner of-which I am at presntly aware of carrying out the intention as applied
to a system of electrical distribution;
but one skilled i the art will readily understand
from the description by the modifications
proposed in said applications, wherein the form of both the generator and converter
in the present case may be modified.

Said application numbers are Serial Nos. 252,132 and 256,561
But there pat numbers are 381,968  382,279


Sparks made a comment in another thread that seemed impt to this so i want to repeat it.

he said ""Steel in the core if you want to make an induction generator yes.  Steel outside the core if you want to make a dynamo. "  We were dicussing the uses of steel or not.   

After reviewing all the said modifiications tesla proposes throughout the first two patents then implmenting them on the 381,970 it becomes clear that these two devices could be combined into one.  The trick is rotating them properly.  The coils have to be a diametriclly oposite positions and run in series. Some of the thicker induced coils wound upon the copper may be shunted in the same ciruct . "Some in series, some in parallel".. similar to an old sm quote we had

"It results from this
that the different electrical phases in the generator
are attended by corresponding magnetic
changes in the converter; or, in other
words, that as the generator-coils revolve the
points of greatest magnetic intensity in the
converter will be progressively shifted or
whirled around"

He also notes many ways to build the two elements the feild coils and armature and different configs they can arranged in. The goal he wanted to convey in my mind was a version of the motor and generator combined into one device with no moving parts and no mechanical limitations.  This may not resemble the otpu but it sure does the others.

1/4 inch plywood - agreed. Then it measures between 3/16 anf 1/4 inch thick. That should allow fairly accurate scaling for other parts. Solid wood sheets that thick were no more available then than now.

If my current train of thought is correct then one of the three conductors of the twin-lead windings is a portion of the collector. That would be the one in-between bifilar control coil conductors.

Wire spools of that size then were also made completely of plastic. A few had plastic ends and a rolled metal core but they were obvious. This one is obvious to me as the all plastic variety. The 'see-through hole' you pointed out would be the normal one - part of the spool manufacture. There is another hole closer to center that should not be there. ref: other pic uploads on this thread.
