do you mean using the bottle to burn wood in? ie cut the bottle and adapt it as a stove / burner?. I use one as an air receiver once i released all the gas then drilled a hole in the bottom and allowed the residue to run out

Coozer made one
See http://www.locostbuilders.co.uk/viewthread.php?tid=108344

made one from a 19K bottle

works a treat


wood burner

I'm making one from a 15kg calor bottle at the moment. It'll look like this:




Tips: have a baffle about 2/3 of the width of the bottle, have the baffle about 5cm above the top of the door, line the inside vertical walls with firebricks, have adjustable air intake on the door, don't bother with an ash tray: just allow a bed of ash to fill the bottom and scrape/scoop off the excess when needed. Don't bother with a grate, wood burns well on a bed of ash and likes air from above, not below. Make a door by using another gas bottle of the same size (you can get 3 doors per cylinder) and make it bigger than the door hole, then it'll need persuading with hammers and standing on it to match the curve of the bottle.

Weld 6mm rod round the outside and grind it back leaving a smooth edge, then weld another 6mm rod about 5mm in from the outer rod, then tap in some fire rope. The inner rod only needs to be tacked in place as it's not on show.

I'm putting a 6mm hotplate on mine for the kettle. Pub CO2 bottles sliced into hoops give you the perfect collar to accept 5 or 6" (can't remember which) flue.

If you want to go a bit more advanced you can make the baffle into a secondary air intake which heats the air before it enters the combustion chamber. If you get it right you'll see small blue flames as otherwise unburned wood particles ignite.

Yep, dead easy. Only thing I would do next time is make the main door much bigger and have the air inlets at the top with just a little door at the bottom to rake the ashes out.

Then the only problem for me is I don't have room in the garage for it!

I fancy making a waste oil.burner

fluidslvr, that has got to be the best 'Locost' project I have seen for a bl**dy long while! I thnik it is absolutely awesome

BTW, I just realised how BIG the entry box is now for messages.

here is one I made. MGF rear disc for hot plate. Plant to weld stip inside to make a better door seal, then add a slide vent blow the door.


stove

stove

the hot plate wont be that efficient but thought it looked good and it was all made with stuff we had lying around

I am for ever seing old gas cylinders in the dyke. I will have to have a go.

some good info there thanks,,,

just one thing thats bothering me, how did you empty/purge the cylinders before you were brave enough to cut them ??

i've got hold of a cylinder, and removed the valve once it was empty,and then filled and emptied it with water three or four times, but it still stinks of gas?


Ray

I believe you have to turn it up side down / hole at the bottom for a few days

Dose anyone have photos of the inside ? do you have to put a grid in them to leave a air gap + for the cinders
Thanks
Jacko

leave the bottle full of water for a few days
smell will still be around but ok to start cutting...

i've welded some support bars in (just below the door) to hold a grid
for the fire to sit on

bottom hole holds the ash pan


gas cy cut

To clean the bottle, remove the valve and fill it with warm soapy water and add a few handfuls of pebbles & sand then roll the cylinder around on the floor for a while (you could put the valve back in fingertight to keep it full) then empty. Add a grate if you want to burn coal. If it's just wood don't add any kind of a grate, just let the fire sit on a bed of ash.
