That last pic makes me think of a smurf riding a bike!
Blimmin impressive though – I love the inventiveness that goes into home baked engineering. Head angle looks a bit steep, or are all track bikes like that?
How much is carbon fibre to buy in its raw state, and how much would have gone into a frame like that?Posted 7 years agorichmarsSubscriber

Depends where you buy it from. Ebay is cheap, but of unknown quality. A few years ago I got about 8 sq metres for about £100 and I’ve made 2 frames from that, but does depend on what sort of frame, size etc. Add about £40 for epoxy (West System), plus a few hundred hours of time, use of a lathe and mill and it’s easy!!!Posted 7 years agoahwilesSubscriber

The standard homebuilt-carbon practise is to use closed-cell foam or even polystyrene for your mold which is cheap and can be melted out with acetone after use. why on earth did he use wood?
a friend of mine has made a couple of diy-carbon frames, he experimented with foam, and acetone, and some scales…
he found that ‘melting’ the foam out of the tube increased the overall weight by a few grams (lots of gunk gets left inside – especially in complicated shapes like a bike frame)
and the foam he uses only adds about 20grams per tube, so he leaves it in.
i assume that the weight of the balsa wood core isn’t enough for our swedish friend to worry about.Posted 7 years ago
