First I want to thank you all for the inspiration for this project. I've been browsing the forums for some time now, found some awesome topics about bamboo frames and realized it coudn't be THAT hard.
So, to make things harder (and because carbon fiber is so expensive here - its like U$$120,00/mē + shipping) I decided to go with Fiberglass
(FULL SIZE PICTURES IN MY FLICKR: here)
So.. I started shopping for bamboo and found these:
Some regular stuff and some Nigra for the stays. The big one? It is going to become a fork in a near future.
Heating the pieces of Bamboo:
So I browsed Cannondale website and got the Supersix dimensions, translated into AutoCAD and cutted the pieces at aprox sizes:
So far so good huh?! Okay but there's a problem. I can't get the right TUBES, dropouts and stuff here in Brasil. Yeah, we don't have (http://www.cycle-frames.com/) and I was in no mood to import metal tubes from the US. So I started working with what I had in hands: FIBERGLASS.
First I decided to integrate the bottom bracket in the structure of the frame. I started by laminating 3 layers of fiberglass to the bottom bracket so it would absorb the impacts it is going to be submitted:
It sure fells stiff but I can't help thinking how long will it last.
For the head tube I got a piece of bamboo and stuck the main head parts in it. Will laminate some fiberglass in it. And for the rear dropouts I made a mold of my main bike and I'll laminate it with fiberglass and some internal metal reinforcements (surprise for the upcoming posts).
This post's final picture include the finishing-pending bottom bracket and my solution for the head tube as well as the MOLD for the rear dropouts.
Tomorrow i'm gonna finish the rear dropout mold and hopefully laminate a couple dropouts and the head tube.
