Those poor pistons! Maybe I should open a home for battered examples,
give them a place to rest while they reseat their O-rings, that sort of
thing. :P

Thanks for the info, TC and Kev.

One more question; as I am to understand it then, a lot of synchro
systems simply match the RPMs of the engines to achieve a consistent
harmonic, while more fancy-pantsy models can actually measure and shift
the phases so that they are cancelling (the least harmonic, in other
words). Or will the phases go to least harmonic naturally if the RPMs
are matched?
