<<<Well, Great Plains sells this type of alternator (20 AMPS) that looks

like it could be mounted to the accessory end of the 13b.  It looks
like it would be a bolt on if the magnet disk (it's not a flywheel in
this application, just a round disk with magnets bonded to the inside)
it is not too thick. >>>>

These permanent magnet alternators (generators?) look like they could be
bolted to a disk that was fastened to the end of the eccentric shaft pulley,
or perhaps somehow coupled to the inside diameter of the eccentric shaft
pulley.  I had planned on mounting one there to provide the second
electrical source that was not dependant on a battery of belts.  The
challenge is to come up with a mounting system that maintains perfect
alignment (if you rigidly mount the magnets to the e-shaft) or that couples
the torque in a semi-flexible manner that is still reliable.  Either way
could be made to work.

These little generator/alternators are used in some lawn tractors and such.
