so, i bought one of those wood gas stoves a while back, the kind that supposedly make use of the gases that wood releases when it burns to get a second "burn" and use the wood more efficiently.
it seems to work quite well, burns longer than you'd expect in a regular twig stove, may actually burn a little hotter and (big bionus IMO) reduces everything to fine ash. all in all it seems like a winner.
trouble is that mine is too damn heavy, close on a kilo with all the bits and the carry sack. sure it's nice and sturdy being made of stainless and all but that's weight i'd very much like to reduce.
as i'm sure many of you know there are a shed-load of videos on Youtube about making your own "wood gas"/"gasifier" stoves and it all looks pretty straightforward.
the guts of any of these stoves is an inner and outer sleeve, usually two tin cans where the inner is the actual combustion chamber and the outer is basically a hot air feed into the top of that chamber.
we don't use a lot of tinned goods in our house but i did end up with what i think will make a good sized combustion chamber. trouble is i can't find the right larger tin for the outside sleeve. i've rummaged through our local Co-op with no success.
what i'm looking for is an unlined tin can about 9 or 10 cm in diameter and roughly 12-14 cm tall (i can always cut a larger one down).
any recommendations? at least if I know what to look for -- the product that comes in such a tin -- then that'll expedite this whole process nicely.
thanks for reading and helping if you can.
once i've got this beasty working i'll post pics to show you all how it worked out.
