Just finished this and thought someone on here might be interested. It's made of 0.5mm aluminium sheet (£6 from ebay) with four tiny bolts holding it together and a couple of coat hanger wire skewers to support the pot. I based it on the Firebucket design but made it in two sections so it would nest...

Microwaveable rice pouches (eg Uncle Ben's) are great. Heated with a splash of water with smoked tofu, black bean or chilli sauce and, if it's a one nighter, spring onions, it's really good. Not super light but then it uses v little water to cook.

I've found a ghetto inflator made from a 2l pop bottle and some valves and flexi tube is really useful for awkward to seal tyres. Search on Singletrackworld forum for instructions.

I can also recommend On-One tyres (Smorgasbord and Chunky Monkey) - mega cheap, good GDP and easy to inflate.
