    Being all posh and too sensitive for roughing it in a tent I wanted to make a camper trailer for my series for when out on little adventures.
    Attempting to keep it age related I came up with the idea of a wood burner for heating but more importantly it would give me something to do till spring and the main build.
    First thing I did was some designs and ideas.
    1. it cant use air from inside as it will use up all your oxygen and kill ye dead.
    2. It has to be small or it will get too hot and kill ye dead.
    3. It has to be safe or the lot will go up in flames and kill ye dead.
    4. it has to be a smokeless one or the world will end and it'll kill us all dead.

    Ok easy peasy :confused:. Paper design.

    Managed to pick up a scuba tank for the body and being 6mm thick should outlast a normal gas tank.
    00 Scuba tank.jpg
    Marked out and chopped up a bit. Time to do some skip ratting as I dont like buying things.

    01 Cutting tank.jpg

    I was going to chop the bottom off but came up the idea of a screw on trap on the bottom to empty the ash out. Off to the sprinkler system engineers and a fiver later came away with a 2" barrel nipple and end cap. I really do need to practice my welding :oops:

    03 Ash cover.jpg

    Having a secondary burn to reduce smoke requires a baffle and chamber so just above the door goes a lump of steel plate with a 'cut out' of similar area to the planned three inch stove pipe.

    04 Baffle cut.jpg

    This gets fitted about 4 inches from the top edge with copious dollops of run away welding :D

    05 Baffel plate install.jpg

    Now for the fun bit. A separate 1" air intake brings air through the back of the tank and up the back wall behind a plate. Once heated the air passes though a piece of box section and squirts out all over the rising smoke. This reignites and the re heated smoke/unburnt fuel is passed under the hot plate and out through t, t'chimley.
    Firstly I made the plate and burner......
    06 Back plate air heater and afterburner.jpg

    and then fitted it.

    07 Air heater and afterburner install.jpg
    10 cutting discs later the welder came out again.:oops:
    I have two welders but my little MIG will only go up to a few mill. This lots like ship building so the big point and spray stick welder was given a blast.

    08 Afterburner install 2.jpg

    It never looked that good again :(
    Before blasting into position I had to cut the inch hole in the back. Tried everything I had available and trust me that isnt alot (did I mention I was tight) so in the end the welder was turned up to nuclear and I burnt a rough hole in the back ready to attack with some grinding stones later. Yes it will take a long time but its all I have.

    Once molten steel was smudged all over it in ever worsening passes I tested the burner by jamming a blow torch in the hole and holding a naked flame around the welds. It didnt kill me to death :eek: So you can put up with me for a little longer.o_O

    09 Testing afterburner.jpg

    Its so beautiful................................:rolleyes:

    10 Burner.jpg

    Started losing the light a bit but it was time for legs. Wanted round ens but had free square.

    11 Time for legs.jpg

    Time to retire to the shed and cut up some more discs coz I luv buying discs I duz.

    12 Legs 2.jpg

    When you have legs you need feet. You also get fewer discs.:(

    13 Feet.jpg

    Well thats it for today. I have spent money and am awaiting steel for the door frame and door.
    Just need a lamp post now o_O

    Coz its mine. My camper, my air.

    Its a very small camper and to use all the air to burn will need vents to replace said air. This air will be cold and therefore need heating. The air will be heated by the stove by burnin..........................................

    It can have its own :confused:

    Yea. Integrated vents will be fitted. Quite fancied one of them twirley roof vents. Only coz I never had one before. £45 :eek:

    Not sure how effective the second burn will be in such a small unit but its there so I hope it at least works a bit.

    Not if its a balanced system. The only time fumes can enter the cabin is when the door is opened for a few seconds when refueling.
    The unit is completely sealed, hence air in from the outside and exhaust out to the outside.
    Thats the plan any road up.

    Im hoping some of the secondary burn ends up in the top chamber so it warms the hot plate enough to boil a kettle :D

    While waiting for supplies I got the modelling clay out this morning.
    I will plainly need a big brass plaque on the front of mi rocket so there is only one thing for it. Time to smelt a couple of old taps and have a bash at casting.
    How hard can it be.

    Now, what to wright on it. Answers on a post card. :D

    Looking good at the prototype stage! :cool:
