The inherently random fiber-structure of bamboo coupling with the need to debride (remove) so much material (bamboo) prior to wrapping seems to render it's tensile strength advantage moot. It almost appears that any attempts, or methods to reinforce these joints pretty much negates the savings in weight that the bamboo accorded in the first place. The ultimate Bamboo bike, I predict, will, in fact, be constructed of "engineered" bamboo strand. In that way the cruder joint 'hodge podges' that are the style today will be far more refined as to process and thereby end-fit result, too. Like supplanting carbon pieces with carbon fiber weave. Not a real head-scratch from an engineering standpoint. Very much enjoyed watching your efforts on the video & Good Luck! Mike Kirwan Kenmore, WA.
Are you for real the more material you take off the less surface area it has to stick to every angle is more surface area you are smoothing things out so therefore there is less surface area this is painfully funny you are doing all that work for nothing and making the structure weaker if you are building a mountain bike if that's all wrong if you are building a 10 speed maybe that's okay you are glueing material not welding bud
The tubes we sell are all ready pre-sanded too smooth with 180 grit. We use a coarser grit in order to increase surface area and provide some mechanical retention.
he's sanding it down so you get a better adhesion surface for the epoxy. a surface with sudden changes in geometry such as a right angle or many of the parts he is smoothing out make it hard to get fibers and epoxy to stick. also, you have to sand he surface as adhesion increases with a roughed up surface.
Depending on the thickness of the hollow bamboo wall, you filing it down could weaken the bamboo.
Hi I'm writing from Colombia, I want to know what kind of glue ar you using?

I've thought the same thing for a long time.
What material used?
The substance to connect the joints is the same substance
not fan of wood bike. by the time all wood will dried then it will lose the strength, crack then game over
I still have my first bamboo bike made in 1995. It's in good shape considering it's 27 years old! I did refinish it once, though.
@@CraigCalfee maybe depend where you use it. in my country it have no chance the best 4, or5 years it will crumble especially bamboo.
