Day 1: jig setup on a 2'x4' flat board (fiberboard from local hardware store). Balsa blocks mounted to jig points using epoxy to become frame lug cores. Bamboo cut to length, then roughed according the BBS's video instructions. Bamboo is then tacked inplace on the balsa core lugs, again using an epoxy adhesive. Seat post sleeve is also permanently epoxied into the pre-bored bamboo seat post. I used a high quality West Sytstem G-Flex epoxy with high density filler rather than the JB Weld included in the kit.
