I've seen cores as small as 1/3mm OD. Through the ID
then goes as many as three wires. Perhaps smaller
than 1/12mm for the wires. Older core boards would
have larger cores, some even bigger than 2MM.

I have a Question for the other core users out there:
How would I test-signal a board, for demos, that is
just a core frame, IE one sacrificed from its stack
and sold at the e- flea market?

> So it's almost like cloth, but made of wire?

Wire "cloth" with a ferrite metal "washer" (the core)
at every x-y crossing of the "threads", then one additional
'thread' snaked through.
