"MWS makes ultra fine magnet wire (used in magnetic recording heads and
meter movements, and those incredibly tiny surface mount inductors) as fine
as #60. The spec is by resistance, not by diameter, though. This might give
a clue as to how they "draw" the stuff, they might use varying tension to
change the amount of stretching, which would change the diameter, and hence
the resistance."

	Very interesting.  After I wrote that original note I 
realized that the wire in the stepper motors of some of the
tiny digital watches must be incredibly small.  Anyone have any
info on that subject?  (I'll admit that's not a TC theme, but
perhaps it will get by just once.)
