I am not sure if I am doing this right, but I wanted to thank everyone that
responded to my stator problem. I can not find a replacement because there
are no numbers to cross reference and a new one from Sonex is $500. I think
the material would be less than $100 and it would be a good learning
experience!
Thanks again,
Tom

The material should be MUCH less than $100 . . . Have
you un-wound the existing wire, measured its length
and put a caliper or micrometer on its diameter? I
have access to several aircraft motor wind shops that
will have class-h insulation magnet wire suited to
your task.

By the way, how much load is on this alternator
in flight? What kind of rectifier/regulator
do you run?
There are two techniques for voltage regulation
on PM alternators . . . the legacy, easy to do,
shunt regulator that essentially has the alternator
running full load all the time. Then there's the
more modern series regulators that load the
alternator only to meet system requirements.
This winding may have failed because of a shunt
regulator . . . I can help you make sure that
your newly rewound alternator is not unnecessarily
taxed.

Thomas, I don't know if you could make it fit, but Harley Davidson has a
couple of different sizes of alternator (dynamo) that you might be able to
adapt. When I replaced mine due to a pinched wire the whole kit was $140
minus the regulator.

Tom,
Have you tried ebay, google, amazon, etc? How about posting a pic with
accurate measurements? Here's the 1st site I found with a google search
for 'motorcycle alternator stator':
http://www.jpcycles.com/motorcycle-stators
It shows pics of dozens of models; you should be able to narrow down the
choices a lot just by appearance, and then counting generating coils &
trigger coils (likely one or at most two trigger coils; should be
obviously different).
You can also try googling 'outboard motor alternator stator'.
Or better yet, have you asked on lists that are frequented by users of
aerovee engines? Odds are good that *somebody* has already found an
aftermarket solution.
