I’ve been thinking about a project wooden bike for a while now, but these are slightly disappointing compared to some others I’ve seen done – especially as they are commercially available. The things putting me off have always been the interface between frame/forks and other components though – I could turn a wooden headset, and even bearings if necessary for example, but can’t see how you’d make a lasting threaded BB shell or mech hanger without metal inserts – which pose problems of their own.
BTW where can I get enough Hickory in this country? or would Ash be more suited if I wanted to have a go at rolling my own.
If you’re serious, I can get you very good quality hickory as used by some top bowmakers – who need very tight, straight and even grained stuff. Their logic behind using hickory is the very predictable qualities it has along a given length. Other timbers that are typicallly used are things like lemonwood and greenheart. Often these are laminated up with contrasting timbers to modify the characteristics of the bow and make them look a bit more bling. The black walnut, wenge, purpleheart and so on (as on some of the bikes on the site) are all used for this reason in bowmaking. Though stuff like lemonwood and hickory are expensive, the volumes used in a frame would be fairly low – so possibly less expensive than you think, though certainly, I’d consider ash as a good (cheap) alternative if I were messing around with ideas. Difficulty is getting ash with the same predictable nature as the above – but I’d consider it a good option, particularly in combination with other timbers.
