My bike started its life as an Origin8 Uno track frame.
My first couple pieces of heat treated bamboo. The point here is to caramelize the sugars in the grass to make the material super-hard. You can actually see the moisture leaving as it steams and bubbles out and it emits a scent like burnt popcorn.
I sanded the bamboo to give a lighter color and the remove the waxy outer film.
I pre-assembled the frame using Gorilla Glue. That stuff is awesome! It expands, filling in every gap and making the pieces fit together snugly.
The electrical tape is wrapped around the joint to press the resin into the hemp twine and squeeze out as much air as possible.
Once I had the frame completed, the hard work was done. I spent the next couple of hours assembling my bike, and it was born on Halloween of 2011!
