The rolled lamination core has been used for certain things, but for a stator tooth the laminations must
all go from left to right, and no vertical's. I have seen a large roll of a lamination strip, 10" round by 2"
deep or so, that was bonded, and then cut into wedges, for axial teeth.
Then theres 'segmented stator teeth' which are very interesting. Most of the work is done, and would only
need a little more machining for a project like this. Or, the motor could be redesigned to use them.
Trying to find some that are the right size, shape, and cost, might be next to impossible though.
I keep looking at a big 21 lb. chunk of powdered iron core, on E bay, for $20. that might be machinable?
I don't know to much about the stuff, but for the price, I can't go too wrong. Could make a good door stop.

Then last but not least, I still have the idea of using stacked steel wires, or rods, for a core. They could be
coated, and easily cut. Plus, being stacked and bonded, they will conform to any shape, and wire is cheap.
The idea is that the super small individual ends facing the rotor, would contain the eddy currents, much like
the thin laminations do. It's like a shredded lamination.
The problem is finding silicon wire or rod, although I have seen steel Mig welding wire with silicon content.
A shot in the dark, but worth a try. And kinda what this motor is all about,.. being able to try different things.
