    Default Gas Bottle wood burners

    Does anyone have any plans or drawing for the Wood Burners made out of old Gas Bottles?
    I know about cutting the things up because I've done them before. Valve out, fill with water, use disc cutter

    Me and a mate have just made and fitted a gas bottle stove into his shed, we will see how his prototype goes and make another fairly soon.

    Have quite a few pictures and will post them up when I know details are to be kept and whats to change.

    If I don't post on this thread in the next month with pics and an update, poke me with a pointy stick and I will get by backside into gear.

    Scott.

    Alright its not exactly a tutorial because my phone camera was playing up so its missing some stages...

    First of all, we got two empty gas bottles, took the valve off, filled them with water just to make sure they were actually empty.

    Cut the tops off both of them making the cut out circle on one bigger than on the other so the bigger cut off top would make a fitted door for the other.

    Then we cut a hole in the bottle for the smoke to escape from and put a grate in as well (multifuel) and thats about where the first pics start.
    Theres a section of steel girder welded onto the bottom (what was the side) and thats where the ashes fall into a little metal ashtray.


    Note, theres still a small hole to cover at what was the bottom of the bottle at this point but will now be tha back, otherwise the smoke will get out at the back of the stove.

    You can't really see it in this picture but theres a big section of what was the side been taken out under the grate to allow ash to fall through into the ashtray...

    The section of girder that will be the combined top and hotplate after I had attacked it with a gas axe showing the hole that the chimney coller will fit into...

    And stove with ashtray and grate removed to show large cutout in gas bottle to allow ash to fall though...



    Getting ready to fit it and in the second pic the door is tackwelded into position just to hold it..


    Finished stove showing chimney collar, door in place and getting ready to fit it..

    Ashtray...

    Door wide open...

    Stoking up...


    Fancy a brew?

    At the moment the draught is controlled by opening the ashtray and theres a intake to make in the back on the new version. just a bit of pipe with a butterfly valve in it.
    Aparently for burning wood its better to have fresh air flowing over the burning wood and with coal its better underneath so we will change things around a bit yet.

    Also I reckon I could do with adding a butterfly valve in the chimney to act as a damper.

    Basically we want to make it as controlable as possible, so it can be shut right down and then also opened right up, after its set up like that we can fine tune the adjustments.

    Given the choice we would have used steel channel instead of girder on the top because that would have given us more space for better chimney flow but it doesn't seem to be a problem so far and the girder was free so we can't complain.
    I forgot to add, we have a design for a backboiler version as well although that would have to be done with a vented system to avoid dangerous pressure build up
    Pretty much most of the steel plates used to blank of holes came from the big rectangular cutout that the ash falls through so two bottles go quite a long way and we have a lot left over out of the bottle with the bigger top cutout.

    That should make a forge.

    Can you make a valve that will fit into where the gas valve was? You would then be able to open and close it with a screw, so infinitely variable.

    Thought of that, will do one but prefer to have flow coming in from the back because the burnt gasses escape from the front, then do a bit of an s bend to heat the hotplate up so don't want to short curcuit it and miss out the burning wood..

    Will put a valve where you suggested though and maybe a window to see the fire cos its nicer that way.

    Basically we will bung a few valves on and then see which ones make the biggest difference.

    It only took about a day or so anyway so its easy to play about with.

    many thanks to everyone with this project.
    Joe, my daughter's boyfriend has just finished fabricating this stove so I thought that Id post the link as a "Thank You"

    Looks really good, I take it you already had the front off an existing stove?

    I like the way the ash door is made from the existing top.

    Just had this from Joe
    Thanks for that but be sure to let them know it was all hand made, including the door and frame, damper and butterfly for chimney. Wouldn't want them thinking I'd just welded a broken woodburner into a gas bottle carcass.

    Oops, sorry.

    Looks good then.

    Is that a prototype for production then?

    If it could be persuaded to slaughter Foxes then I would expect that Joe would put it into immediate production

    Have also built a forge to use up some of the bits left over from building the stove.

    Default Zinc

    I'm really quite worried about the use of gas bottles without removing the zinc (galvanised) coating first. I am currently making a small stove for a sauna and have taken great pains to remove the zinc by using electrolysis. Some people grind it off some burn it off in thr open using a very hot coal fire. Zinc when heated up is very poisonous, those that weld it should take great care.
    I do think that gas bottle stoves are really good, the steel is fantastic quality and its good to reuse old stuff. ed.
