Good work! :P You might need a bit of a wider wheelbase though!

For the belt, good old V belts do the job just fine. The 10mm ones wrap around a surprisingly small pulley (like 25-30mm) which was the problem i had with the standard 12.5mm wide type.

I'll be getting some of the urethane weldable V belt to try very soon, but if it works like the 3mm round on my beetleweights i expect it'll do an even better job It can be had from mcmaster if anyone in the UK can order it in for you.
