I’ll stop the puns soon. I swear. Built some standoffs for the headtube and rear end. Check em out: The degree of accuracy of this jig is probably not within the tolerances of a well made bike, so I’ll have … Continue reading
Started work today on a flat wooden jig that will hold the frame in place while I tack the joints and generally put it together. I found an old cupboard door, which to my luck had 33mm holes drilled in … Continue reading
Just like the out of work actor Tobias Fünke mistakenly finding a Tractor Pull magazine (thinking it said Actor Pull) and seeing thousands of parts inside, I too became excited when the delivery man arrived today with my bike parts: … Continue reading

Titanium seems to top the list in CO2 footprint… ouch!
I’ve been researching bio resins for use in the bamboo frames and discovering a whole beautiful world of people making resins out of things like soy. There’s an interesting PDF here that details the environment costs and benefits of creating … Continue reading
I’ve selected the 7 culms (fancy word for a bamboo pole) for the first frame. Here’s a pic of them laid out into the respective parts of the frame: And here’s a view of the thickness of the downtube: I … Continue reading
Bamboo is susceptible to mould and bugs if left untreated so I’m planning on following this procedure for curing the bamboo, which basically involves soaking it in borax and boric acid solution for 2 weeks. After this I’ll dry the … Continue reading
