Almost any tandem company can sell you an eccentric bottom bracket premade. You might also talk them into the matching bottom bracket tube that you could weld directly onto your frame. I'd suggest CoMotion or Santana. They both make frames from multiple materials.

It does sound like a search for the biggest chain ring you can find would make sense too, so that you can use a larger cog

An eccentric bottom bracket would probably be a better setup for adjusting chain tension then that spring loaded chain guide you've opted for. I had just one like that for a single-speed mountain bike and it added a noticeable drivetrain drag compared to "magic gear".

Tomorrow is another day, as they say.
On the second comment about sprocket sizes, I too had read (perhaps in Bicycling Science?)that more teeth = higher efficiency, possibly because on a bigger cog the chain links are swivelling through a smaller angle. Will the transmission geometry allow say, 78/18? Might give you a watt or two.

Why use a 12 or 13 tooth gear? I am no expert at all, but according to what I can remember it takes away more power than a 16 tooth gear. You can easily keep the same ration by using another number of tooth at the front.

I think it's just a very small difference, but it might help.

I guess all you can say is "Doe!".

"And what have you learned from this, grasshopper?" Each set-back in life is meant to teach us something.

Maybe, we learn how to swear better.

With your kind of tenacity, this problem is 'nuttin'.
