Awesome job! I have to admire someone who doesn't just post "How do I....?" questions and just gets after it and starts building.
My only observation/concern:
Seems like using metal tubes to get your tubing diameters might not be the best solution- I've never done a bamboo bike, but the ones I've seen on this forum all use bigger diameters than what you're using.
The proof will be in the finshed frame though- can't wait to see it!
