his material seems a bit less than the best because of the knots.

 

In the good old days of chestnut coppice the local walking stick manufacturer used to insist on sweet chestnut that had grown 4ft from the stool in one season to get clean sticks. Similarly cricket bat willows had any adventitious buds rubbed off the keep 12 ft of clean stem. So simple cultural techniques should improve the strength.

 

I am fascinated with the possibility of a biologically derived epoxy resin but think I would compromise and use carbon fibre instead of the natural yarn.

Nice. The joints end up a bit like the reinforced epoxy fillets used on ply for modern boatbuilding. I've milled some bits in the past for a local chap who made hollow core wooden surfboard with Thuja, they were built up almost identically to a plane wing, with a central spar and shaped ribs across. They end up really light and amazingly stiff and tough. The shell is coated with a thin epoxy finish and a thin glassfibre tissue that is transparent when wetted by the epoxy.

 

The board builders were very keen on plant based resins, I think it's commercially available now from a few firms. Tree to Sea Wooden Surfboard Builders Forum - Index page
