Thanks to A Vagabond for the suggestion

I cut the cogs from chopping board, it's great stuff!
I drilled a daisy pattern in the board and then pushed out the middle, which formed a rather handy cog. I sandwiched four of them together with a bearing in the middle to make each gear.
The motors and planetary gearbox come from ultra cheap Tesco 9.6v drills, it's basically a complete unit in itself, just stick a gear on it and you're good to go. They're powered by a Novak M2 Dig speed controller which is more than it needs but I might put larger motors in later on. I really can't overstate how good chopping board is for prototyping, it's strong for its weight, easy to cut, you can even heat and reform it. Oh, and it's cheap too! ;-)

So, and sorry to keep asking questions, did you cut everything that is white from the chopping board? The stuff in between the tracks I mean. What are the tracks made from?

No worries!
Everything that's white is chopping board and the tracks are made from bike chain and aluminium pipe bolted together at every other chain link. ;-)
