The Carbon Fiber Layup

Posted: 27th June 2010 by Nigel in Bamboo Bike, The Build

Once the frame was tacked with 5-minute epoxy, we were ready for the layup. Here is what you will need for a wet layup: 1. Carbon fiber tow, basically 5mm wide unwoven carbon fiber (find it on eBay) 2. Epoxy resin and hardener suitable for use with carbon fiber 3. 100 grit sand paper 4. […]

Tacking the Frame

Posted: 22nd June 2010 by Nigel in Bamboo Bike, The Build

Once all the sections of bamboo have been heat treated, cut to length and mitred, and once the metal sections have been prepped, then you are ready to prep the frame for a wet layup. A wet layup takes several hours, and requires the frame to be held at different angles and loads to be […]

Last night Jame Kay and I put together the frame and did the wet layup. I will do a complete post later, but for now you can look at the pretty pictures.

Mitring the Joints

To ensure a strong frame, you need to mitre the joints well, and it is a fairly challenging process. When you join two square objects, it is pretty straight forward. You just cut a straight line and bam! you are good to go. Joining two tubes is more complicated, since you have to cut a […]

Donor Bike Number 2

The easy thing would have been to cut up the track frame from my donor bike. It was about my size, so I could replace the steel sections, one at a time, making only small adjustments to the frame size. That, however, would go against my goal of minimizing waste. Instead, I sold that perfectly […]

Heat Treating Bamboo

Heat treating is an important process for preparing bamboo. Essentially it removes a lot of the moisture, making the poles lighter, and most importantly it cooks the sugars in the shoots. Bamboo is a species of grass, much like sugar cane, and is full of sugars. When these sugars are cooked, they turn from being […]

Bamboo Harvest

Posted: 9th June 2010 by Nigel in Bamboo Bike, Working with Bamboo

Today was an exciting day; I harvested the bamboo to use for my bike. I had been searching around for some appropriate timbre bamboo, and I really didn’t find anything. All commercially available bamboo was from Asia, even though it grows like a week here. Fortunately I found someone on craigslist who was “thinning out […]
