Hello! I'm thinking about building a wood burner, I have a friend that works for my local recycling company,so no problem getting the right size bottle. Do you need to be able to weld .I don't want a too big burner as it needs to be transportable to use outside whilst Wildcamping .Now I know you can buy ready made portable ones for £100 plus,but I'd rather build my own and spend less than that.Under £100 really as I have a few other builds on the go. So if anyone has any ideas lets hear them and we can do a seperate how to thread. Stephen.

Hi Stephen, I too am thinking about making one (after recent thread by WVW). Welding would be a handy thing so that you can fit the door hinges and a catch as well as the chimney. There are quite a few YouTube vids on how to make them. I am starting with a really small one (3.9kg bottle) and see how it goes.
I will keep you posted.

I've got one already thanks Will. If it turns out OK might look into building more though!

3.9 kg is a good size ,much bigger is harder to transport.

If it turns out all right, you'd better build some more as me and my BWV and 4.5 kg calor bottle will be camping outside your house until you do! Good luck, I've spent hours this weekend on line trying to solve my heating problem, and am going to have stay off WC for the rest of the night as a couple of people are really getting my back up on my gas bottle thread! Keep up posted on your progress.

i did think of doing one with pictures butjust too lazy at the moment. here's a few ideas though empty the bottle thoroughly in the open air
the valves are really tight and you'll need a good long spanner ,stilsons are best and a lump hammer to get it off
fill the bottle with water to expel rest of gas
make a flue collar either by luckily having the right size tube or bending a bit of 50x3mm bar round a bit of drainpipe or something and welding the ends together,this should be a snug but not tight fit in the flue pipe.
mark round this collar on the top of the bottle and let out enough water to be able to cut this hole with a jigsaw-i'm very nervous of gas bottles ! tip out all the water then weld in the collar
you need 2 more holes,one on the bottles shoulder for feeding the thing and one just above the base for clearing out.what i normally do is mark these out and cut out about 3/4 of the way round.then weld the hinges on before finishing the cut.then use something like 20x2mm welded round the doors as overlapping flanges.you'll have to make a hole in the bottom door with a sliding or rotating cover to control air inlet
make up catches as you see fit then stick a bit of flue pipe on and fire it up outside,get it really hot to burn off the paint there's various colour heatproof paints you can spray it
this is a fairly simple stove which will keep you warm,it needs to be better sealed and a flue damper fitted to stay in at night,but fires up so quick in the morning i never bothered.go to bed when the vans toasty get up freezing,quick clear out bit of paper and kindling,ignite,kettle on the hob and back to bed till van warms up.lovely

Thank you for that. I too am nervous of gas bottles and I have heard about the filling with water trick before - good idea! What do you use to make the cuts, I thought about using an angle grinder to cut out the doors and then welding some narrow strips of steel around the edges to make a flange for it to close against, but what about the circular holes, can you get a hole saw for metal?

Could you use exaust pipe for the flu? I mean the big bore stuff!

Post by robmac on Dec 16, 2012 19:06:17 GMT
I have heard about this being done, but you have to clean them regularly due to the narrow guage otherwise they clog.

Oh, ok something a bit bigger bore needed then.

metal cutting jigsaw blades cut lovely but i use the 1mm angle grinder blades for straight cuts,youve got the flange idea good!any pipe will do for a flue,the bigger the better draught or sucki'd normally put 4inch on a bottle,but had a bus exhaust pipe about 2 1/2 inch on a fire extinguisher,worked ok.another thing is the flues can rust out quite quick

Purging the gas before starting cutting might be a plan Just finkin'

any fireproof vessel can be a burner.think how it works=you light a fire in a container,then control the air that feeds it and the exhaust that vents it.i once met a total twat by any standards,skinted and broken down in france with a girl and newborn,who'd chopped a hole in the top of his oven,got a bit of flexi flue in there and lit a fire in it.bit[well, very]smoky,but they were warm. pressure vessls are good,like air brake tanks off lorries etc.what i like is these things have no value beyond scrap,so are easy to get

Also, could a flue damper be as simple as a loose square of metal placed on top of the chimney?
