That is one sweet bike you are building. I love the idea of a bamboo bike. I have seen several nice ones in my area. I saw Craig Calfee build a couple at the Philly Bike Expo. He now uses fiberglass casting tape for the lugs. It has a big advantage that the polyurethane adhesive is sticky (Unlike epoxy) and it naturally compresses itself. He said the casting tape joints rival his carbon joints for strength when tested. They are easy to make, but need to be painted as they don't come out as nice as the artwork you are producing.

I watched several frames being wrapped and it was easy. Open the package of casting tape. Wet the tape and go to work. It sets in ~5 minutes. Much cleaner than epoxy and no need to compress the joints.

He has just started a kickstarter to sell kits with the jigs.
