Heres a small stove that I can take walking.
Main body is an ikea cutlery holder that i got from a scrap pile (also available from home bargains) with a hole for loading wood cut in the side.
Pot stand is two bits of 4mm stainless rod, bent to retain in position when in use.
Windshield (for use with meths burner) is a bit of ally cladding.
Meths burner - two lager cans and a coin.
Cookpot - stainless car boot kettle (50p) with the handle cut off and the spout squashed in so it fits inside the stove.
Piece of camping mat wrapped in lagging tape for removing the pot from stove when hot.
Tube for blowing air in if required when lighting.
Nylon bag from army store - £1
Runs on small sticks, pine cones etc or meths if using burner. Full pot of water rolling boil in well under 10 minutes.
