Old pram wheels to make a "Trolley" (Go Kart) anybody?
Yep, did that too. I was never able to find a long enough piece of timber, for the spine, so I remember trying numerous times to nail two pieces together, to lengthen them. It was always collapsing in the middle. The only way we had back then, to drill holes in wood, was with the use of a hot poker, to burn its way through. I eventually gave up on it, when I was bought one of those Triang scooters.
