Wheels are now secure!

I bit the bullet and bought a pillar drill from Screwfix, some 120mm trolley wheels and some 3/8th bolts from a Land Rover Defender. A quick blowtorch and heat press later, the wheels are on!

It works, but seems to be pulling off to the right at low acceleration. I'm hoping that this is just the wheel catching on something and not something more serious. A thought in my head is that I've managed to lock the gearboxes in different gears, but I'm not sure if that's even possible.

I've applied for Robodojo now, so pressure is on to get finished!
