Frame

Frame
My bike started its life as an Origin8 Uno track frame.

Sections

Sections
I cut out all of the main sections of tubing and saved the joints.

Bamboo Forest

Bamboo Forest
After many failed attempts at finding decent sized bamboo, I finally found some!

Polished

Polished
I used a Dremel to remove all of the rust from the pieces of the old frame.

Heat Treated

Heat Treated
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.

Parts

Parts
All of the parts that will eventually become my bike.

Wheel

Wheel
My first wheel I've ever built! Actually turned out really well.

Shape

Shape
Its starting to take shape!

All Cut

All Cut
Everything completely cut and mitered. My rear wheel will fit perfectly inside the frame.

Sanded

Sanded
I sanded the bamboo to give a lighter color and the remove the waxy outer film.

Gorilla Glue

Gorilla Glue
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.

Joint

Joint
Hemp string from Wal-mart and fiber glass resin. This is what holds everything together.

Covered Joint

Covered Joint
The electrical tape is wrapped around the joint to press the resin into the hemp twine and squeeze out as much air as possible.

Laquer

Laquer
The first of two coats of laquer.

Done!

Done!
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!
