I made this one from planks screwed together, with plastic/pneumatic wheels from Machine Mart on solid threaded axles, the wheels held on with domed nuts. The axles were attached by being passed though big wood blocks attached to the underneath. It was solid but heavy, I put a lot of effort into the arrangement of bolt and washers for the steering so as to make it handle easily and it steered and cornered really well. I built it for a buggy race, hence the strong pushing/rollover bar, but the problem was the weight, so loaded with a 8 y.o. pilot it was pretty hard work on a soft school playing field and we came second, pushed by me and my rugby-playing neighbour. I built it to fit exactly in the back of our Land Rover 90
