Cheers guys, I had considered something similar to the angle ali idea but I wanted to check for a lighter suggestion. You know the weight limit worries!

As for the gear, Ill see if I can find something light to hold the axle in one place for the time being

Sorry James but no. The gears are (quite rightly guessed, Ewan) from technobots and the wheels are from a hardware store
