step by step gas bottle log burner
blakep82 - 22/3/11 at 12:00 PM

has anyone got a sort of step by step guide to making them?
the, er 'travellers' down the road have gone, but they've left at least 6 big gas cylinders, i see a bit of an oppertunity to make and sell a few. but not sure how they're made, any guides anywhere?

i found a few threads on here about them, but only shows photos of the outsides of them, no inside photos, or what parts they need (air holes in the bottom? etc)

Flo gas gas cylinders are free, so not such a great money saver

If you google 'Gas Bottle Wood Stove', there are many variations on the theme, I've a couple of bottles I was keeping for the same reason.

Ive had a play around trying to make a good burner before from a old cylinder but not much success.

although you can find good plans on the web to build them.

if you want to heat a garage this one below is a good plan and you can run it on pallett wood which is very easy to come by.

i us plans from the redneck sites.

i built a pool heater which you can see below for my 12' pool which holds about 6000 litres of water.

with that other heater in place i then added 2 x 50m mdpe black pipes rolled up in big loops. this runs when its warm outside.

with the solar cover on the pool and the pipes running all day you can get the pool to about 34 degrees.

Then run the redneck pool heater for 2 hours and your at a nice 40 degrees pool.

anyway soory.

back to your idea of making the gas burner heater. good idea but it will rust very quick and no paint stays on it and then if your mrs is like mine you wil have to get rid.

good luck though.

Here's a picture of mine during building.



Basically, I opened the tap and let any excess off and then unscrewed the tap at the end (this can be very tight and I had to saw it off another). I then tip the bottle and leave it for a day or two and then fill it with water to force anything else out and then leave again for a couple of days. Then comes the scary part, I lit a match and put it over the top and dropped it. Queue a really scary 1 second WHOOSH then you're done.
I cut the base ring off the bottom and then cut that in half and used it for the legs, carefully cut the door with a slitting disc in the grinder, though I wished i had access to a plasma cutter to keep it neater, then I cut a hole in the top around where the tap was to act as a flue and I put a small collar ring around this made from some flat steel.
I have since cut a rectangle in the door piece and welded on some mesh then welded the door back on with a brass latch rivetted on the other side and after the first burn, the paint comes off, all rubber like. A razzing over with a wire attachment in a drill to clean it all up and then I used etch primer and hi temp black stove paint and you're away.
TBH I am thinking of drilling a couple of small holes in the bottom corners to get a bit more air underneath and help burning but it works fine.

awesome, found a good guide in indestructables.com, played it safe to make sure i'm not breaking the law and will go to collect them, and probably repaint them, just in case then i'll have a go. i know the paint will cme off, but you know
copper winked and said i shouldn't have asked. i said i just wanted to tidy the area up, and make a few log burners, so its keeping the country tidy, and recycling, he said 'I like it!' and walked away. he can't say yes to it, but he wasn't going to say no

The hardest part is finding something to make a good chimney. To burn wood efficiently you need at least a 5" flue. If you can find an empty co2 cylinder or fire extinguisher and cut the ends off it you should be good to go.

hey blakey, I've been on a gas bottle woodstove course ^_^ Mine is 90% done but I've not welded on the top yet so I can take some pics to show the baffle while it's still visible if j00 want?

I like the horizontal approach on this one...

CHIMINEA-GAS BOTTLE LOG/WOOD BURNER-PATIO, WORKSHOP ETC on eBay (end time 13-Apr-11 20:19:49 BST)

Not suggesting that anyone buys one - just think it's an interesting bit of lateral thinking (literally!).


blakep82 - 22/3/11 at 03:51 PM

that wood ( ) be awesome Ben!

hmm, interesting idea David, horizontal, more wood, cut the whole top off and hinge it. could be interesting. might do that with one of them


welderman - 22/3/11 at 04:05 PM

we knock these out when we have som spare time, vry easy to make.

I think the main benefit is that the hot gases have to travel further through the burner before they go up the chimney.

Personally, I'd stick to a small door on the front, as in the picture. It would be fun to have a smoke-box door with 2 handles, like the ones you see on steam locomotives! They would be very easy to rig up...

Here it is...



Knowing what I know now about burning logs I would have made the door much bigger and put the air vent in the top of the door.

Chimney came from a fabricators, got about 7m for £25ish.
