the two main curves on the frame are actually a laminated from lengths of 4mm ply, so they should avoid warping alright, the seat post may be a worry in years to come as it is just an oak post. no extra special finishes as yet so woodworm may be a problem in years to come, as for catching fire in afraid I don't think I can pedal quite that fast sir!

I made a wooden bicycle recently! - more pics if you interested http://boards.core77.com/viewtopic.php?t=18830
I bought BB shell, drop-outs, and head tube from ceeway (really helpful guy too) check out - http://www.framebuilding.com/index.htm for that!!then you don't have to butcher another frame!!
the BB and Head tube were just bonded into the wood with good old Araldite this has held up for the short amount of use the bike has had, it wasn't designed to be used!! I think the fiberglass should hold the BB but I would be really tempted for reinforce it with something (maybe some bolts hidden beneath the fiber glass)
Hope this is useful, if I can help with any other info just send me a message!!

Few days old now, found this earlier and it had me convinced for a while....and apart from the x-ray picture!!

The ironic thing for me is that on a recent visit to Portsmouth universities design department they were looking at the use of carbon fibre in hip replacements.....the problem was that if the joint snapped it would almost certainly give the recipient cancer, don't think bontrager thought that one through!!!

I dont think very much of the skill level of my teachers but about the only thing they have said thats been useful is try to keep it simple. The front runners at the moment are the rack for "for carrying stuff" and the mudguard both of which should be reasonably simple, my teacher prefers the rack as all I need to work out is the mounting system so we shall see!!
where are you teaching the design course rupert?? is it uni level?

Hey guys thanks for all the responses,
1) Had considered a wooden bike but thought it was to much work overall.
2) Chain tugs for forward facing dropouts, i will take a look at a design but it would probably end up being quite impracticable both to make and use.
3) Redesigned handlebars, well I'm considering a more ergonomical handlebar with shaped hand grips. if that sounds good, although not radically redesigned.
4) A small easily removable mud/splash guard sounds pretty and ill definitely piece together a few designs.and tommid you could just buy one you cheapskate!!

Hey, I'm new on here currently building my dad's old road/touring bike as a single. I was hoping you guys and gals could help me out a little, I'm currently taking a design and technology A-Level, in which I have to design and make a "product". I'd love to make something bike related, so I wondered if there were any problems you've found cycling related eg Handlebars, Bike Racks, Lights etc. Any ideas would be awesome!!
VB has already suggested a storage rack similar to those found on touring bike that don't require the fixings, that track and road bikes don't have, to attach it. This has become my front running idea from its relative simplicity.so any comments on that idea +ve or -ve or any other ideas would be great!!
