I also found this as a source for tubing; www.themetalstore.co.uk/products/mild-steel-tubing-16-swgI think the 3" would be good and probably enough in a 3 metre length for a second build. I would make spigots to attach short lengths together. Not stainless but easy to paint black, even though I still think I will try and find something free!

Nice link! Thanks Rob,I've found another couple of links to burner makers,but they're over £200 each!

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 Damn, part of the swop deal for the blue gas bottles was an old fire extinguisher Flexi flue!!!! ;D ;D ;D I didn't know such stuff existed, I thought flues were all straight and you could only get corner joints. Flexi flue would be very handy for my van. I'll google it.

I've got to take some old batteries down to the scrapyard this week, I think I'll have a nose around and see what else is about!

the site with the frontier stove on has some flue pipe on there to extend the one on the burner and a natty water heater to fit round the flue pipe

you can make these quite easily out of old gas bottles. though it is quite a bit of work and time and you may have to buy some welding rods and fittings

I'd like my flu pipe to be in several pieces so that it packs into a big bag for transportation .

proper single wall stove enamelled flue pipe comes in 500mm and 1000mm lengths and is about 40 quid a metre and 40 quid for each joint'DON'T buy a cowl,easily made from a bit of tin or ally. metal stockholders sell good steel elbows in different sizes for pipe welders,a 4 inch elbow cost 8 quid a couple of years ago.you can either weld them in the back of the bottle as they are,or cut a bit off to make a collar.if you cut a bit off like this you can als reduce its diameter by cutting a bit out,sqeezing the ends together and welding

Great link.
I've started on my stove, but I've cheated! I've stripped all of the fittings off of the bottle and marked where I need to cut. My son then came home from work for lunch and said that he would take the bottle in with him and do the cutting (he works for an engineering firm). Hopefully have some pictures in a couple of days.

The 6kg bottle would make a nice size little outdoor stove/ warmer for two or three people. I think I would go for a pipe coming out the back. Maybe just one flue section a foot long (detachable for travel). A flat top (hammer flat?) so you could boil a pan or a kettle. A separate feeding hole (like the Kelly Kettle) so you can drop in fuel and sticks etc without opening the main door, and an ash plate, with air vent below.

This all sounds good! I've managed to source a stick welder,going to borrow it from my brother from another mother,he's bringing it from Wales in the new year.Should have a bottle soon . Yes Vern ! That sounds about what I'm hoping to achieve.

Funnily enough I've been looking around at welders today! Although I've got use of my sons at the moment.
The design of mine is to lay it on it's side, I have then cut off the top curved surface and then replaced it with a flat hob, so it is the same in shape to the frontier stove. The chimney will be cut with a curve so it sits on the back top of the stove and not intefere with the hob too much. (I know what I mean anyway!).

Aldi often do cheap welding kit, Lidl prob do it too, as they seem to stock similar products a few weeks apart. Not much help for now but worth keeping a look at what they get in stock (see the special buys on the website) if you're thinking of buying a welder in the future. I presume they would be elec welders.

I have an arc (stick) welder. I am very good at blowing holes through plate with it ;D
Although the plate used for gas bottles would be thick enough to weld easier. However, most of the fittings of the bottle could be built using nuts and bolts and drilling holes. And for things like the flue and feeder tube can use square section pipe and angles on each side again with nuts and bolts and using fire seal to seal the gaps. Holes can be cut with a metal bladed jigsaw or an angle grinder and drilling the corners.
Just a thought for someone like me who isn't the world's best welder.... I think you could build a fire bottle without. I'll try to sketch my design and details out and post a pic for people.

if you can afford it,a DC inverter welder,140amp is a lovely lightweight welder.still a stick welder you can get a TIG welding attachment for it.when using a stick welder,put the stick in the holder and bend it down so its noticeably curved,this and keeping your elbow into your side will help control.i spark up on the earth clamp then when its running,go onto the workpiece

Good idea Vern ! I'd like to do minimal welding on mine as I will also be practicing on it I don't know what this welder is like yet,so hoping to collect more parts before it arrives.

I've read articles where people have used fireplace cement instead of a weld for chimneys etc. but I am a bit dubious about this, especially for a portable unit.

My experience with AC arc welding is that it is bloody difficult to get a neat (or sometimes any kind of) job without months of practice. I had a go with someone's MIG once and it was soooo much easier. I will draft up my weldless bottle design for comments I would use cement /fireseal compound, rob, on mine, but I would use it in combination with bolted angles more as a seal rather than for strength.

From experience with open fires and wood burners, fireplace cement needs replacing every year or so, eventually it just cracks and falls apart.

Yeah I looked at these Jess. They also do a water heater in the form of a shroud which goes around the Chimney - I thought a kettle would be cheaper.
I will probably try and copy the spark arrestor thingy, and I thought about experimenting with Silicone ovenware to make up a flashing kit, although a lot of testing would be needed before I would trust this.

Those sealants look interesting Vern, Temps up to 1250 deg is pretty impressive.

these are the flue collars i use.i also thought of cookware but its all a bit flimsy compared. for a cowl i cut a rectangle of ally or steel,round off the corners,bend it over my knee and pop rivet it to the flue.another word on welding-practise on new metal not old !,get a few offcuts of angle and join them together
