Tom's advice is very accurate, and my reply may have been a bit misleading.
Thanks for the clarification, paisano. My main concern is debris getting
into the engine from the shaft failure. The teardown would 1. clean it up,
and 2. spot any damage that may have occurred from it. While open,
tolerances would naturally be checked. Costly? Yea, it may be, but what is
it in comparison to your life. I would estimate a teardown for a little
Continental, done at the local wrench's shop as about $2K. Lose an engine
and you'll spend the $2K in medical deductibles if you're lucky. I guess
I'm getting old, I don't want to take those chances any more.
And speaking of Barnstormers, Tom G. has a fabulous Forney project for sale
that I was about to bite on. If anyone out there is looking, I STRONGLY
suggest you find him and convince him to sell it to you.

Hi Sean. Before you start looking at the engine as the culprit, check out
the generator. Think about it. The shaft most likely broke because the
generator wouldn't turn. If it was an engine drive problem, the shaft
would not break, the generator would just stop turning. The usual culprit
is the generator - i.e. the generator starting to lock up (or actually
locking up) vs. anything in the engine. Shouldn't be any reason to get
into your engine unless your A&P sees some sort of damage at the generator
drive on the engine side. An engine teardown at this point would be a
piece of very costly advice. The generator shaft is
the weak point - usually by design - in the generator system and, while a
broken shaft doesn't happen that often, it does happen.....usually with no
damage to the engine. First suggestion is to inspect the generator - it'll
mostly likely have a problem - along with the generator drive system for
any damage, then proceed from there. Your A&P should know what to do.
