We've finished. We got reverse working today, which was the last problem, and we've all been tearing round the garden at 5 mph like Jenson Button. It sounds like a monster truck but starts first time and goes up a 1 in 2 slope. It's going to be wicked in snow with chains on. Bob says he wishes he'd had it when he was younger; me too.
I'm particularly proud of our home-made steering pinion. The original on the right only had three teeth left. The cog on the one on the left was made from a piece of scrap bronze using nothing but a hacksaw and files. We ground down a bit of iron bar, tapped a thread into it, and drilled three shear pins to stop it rotating.
Who needs engineers?
