I will by making the plan some time this week and then build a 1:1 scale model of the bike and post some pictures. BlazingPedals, you say you don't have much experience with 'tweener bar setups, what other types are there? Are there some major advantages/disadvantages? LWB guy, I want to attach the stays with the main tube by sanding and scoring, gluing them together, wrapping them in hemp fiber and then soaking the joint with epoxy. For the places where metal meets the bamboo I was planning on doing the same; scoring, gluing, wrapping and soaking. Where would/could the angle aluminum that you mentioned be used?
Sorry for the lag in response been busy with school,
