Wow , that is some build !! , I would like to see more info on the build if I could, cheers for that link too John , it still did not go into too much detail of how say the chain etc was done, I bet that £22,000 would still not work out too much per hour in the end mind. A total work of art 
Cheers Mick
Hi Mick,making the chain would be fairly straightforward but somewhat tedious if you disassembled a real metal chain and used the outer link and inner link components as templates to cut and shape the wooden ones.
A far quicker and more consistent method would be to use a CNC mill to machine elongated profiles of the inner & outer links onto rectangular blocks of a dense timber(beech maybe)and then repeatedly slice of thin veneers from the profiled piece thus giving you a large number of links in a relatively short time.
I believe the rollers and through pins could be successfully machined from Ramin doweling with the pin ends being bonded to the outer plates,or even swaged to give an authentic riveted assembly as per original.
The thing that's easy to overlook when looking at the engine & gearbox of this wonderful wooden Norton sculpture is the fact that old school pattern makers made wooden replicas of all the cast components necessary to make the real thing in ally or magnesium,and did so on a daily basis.
If you have a bit of spare time to kill(an extra lifetime maybe
) you may be tempted to make a life size wooden replica of the super sexy Honda 250cc six cylinder racer,It would certainly be different and worth a few shillings.
