Soooooo.......... out with the plasma and the mig and we have.... still some work to do but not bad for an evening in the shed Hopefully next weekeend will be dry enough to thread a flexy flue through the roof and we can fire it up ;D Al

A lick or paint and that would be good enough for the house!

Thanks peeps ;D It will burn wood, coal is harder to do It will end up in a neighbours house when I build the next one as I hope to sell a few after seeing some crappy ones on egay for silly money

mate of mine built one for burning waste oil last week, had to be careful with the breathing or it started pulsing the exhaust, which was quite scary.

Been looking at a waste oil furnace blaster for melting and casting ally etc Start on wood or propane then switch to oil, apparently gets hot enough for cast iron!!!

Looks good .Done a few of these over the years.Got all the bits cut for the latest one ,just gotta weld it all up. Did you put a baffle over the chimney hole inside?

looks great i'v gotta get a plasma cutter ! made quite a few of these & the 1 in the workshop must be 10 years old now , so they last well. also had 1 in my living room for the past 6 years. can fill it with coal, close it up & it will burn for 8-10 hours, easily all night. it was shot blasted & then done with bar-b-q paint. it takes the serious heat , even when the bottom half of the bottle is glowing orange ;D made some minature's from the smallest size bottles too, for people with camper vans & most come with a 'hot plate' for keeping the cuppas warm .

hehe, we have certainly got some talent on this 'ere forum ;D ;D The chimney is baffled and wll have controlable air inlet. Lasting 10 years is good news, especially if coal is used I will have to try a coal version, how thick steel did you use for the grate? Al

First one made didnt have a baffle ,we had fun stoking it with wood to see how high we could get the flames leaping out of the chimney,the roar was awesome! chimney was 6 ft high ,plus 2ft of flame usually!The bottle glowed almost transparent .Sitting on the patio in winter ,we couldnt sit within 6ft of the thing ,it burned our legs! The ones with baffles burn the smoke from the wood being burned,so supposedly more efficient.

I have built patio heaters before, fun stuff watching vertical blowtorches ;D ;D By baffle then I think you mean the plate inside the burner that makes the smoke travel along the burner inside then back again over the baffle to the chimney? Not got one yet but hope to, Mine has a turnable disc that shuts off the chimney to shut the fire down to keep it in overnight. Just been out in the shed and made the air pipe, gone a bit ornamental to give it a more funky look, pics later ;D

Yes thats what I mean by baffle.Air vent is a good idea ,as mine usually have a loose fitting door to draw air in from the gaps!Not good for indoor use due to smoke escaping,but good enough for the patio!

I will have to try a coal version, how thick steel did you use for the grate? Al the 1st grate i made from half inch round bar, it lasted about 3 winters. the next 1 was made from some cast 1'' grid, looks like a storm drain cover, it came out of a skip. it had to be made in 2 halfs so it would go through the door. i'v found a few usefull pieces of cast grate in local scrap yards. when i'm burning just wood i put a 3mm plate on top of the grid to hold the ash.

so what are the list of parts, come on you know you want to list them.. I'm tempted to make one on a BIG scale, need BIG heatz in a 16 ft by 70 ft workshop hahaha

Very nice builds there, I never thought of using a gas bottle. I need to build a stove for my living room. It has an open log fire, but its gash - all the heat just pisses off straight up the chimney. I reckon a wee stove will sit nicely infront of the fire and heat the room better, with a length of flue pipe up into the existing chimney. This is one I built last year for my brother in law.... He found the idea for thee original (which is round, but we don't have a sheet or tube bender) on the net. The idea is that the tubes around the sides are hollow obviously, they draw cold air in at the bottom, which is heated by the sides of the stove and flows out the top of the tubes. It works really well, when its burning normally, you cant put your hand in the airstream coming out the top! It has a flap in the exit,but he never uses it, he regulates the fire with the air intake, which is the pipe low down at the front. A bolt is welded to the back of the cover and a nut is welded on a strap inside the tube, so screwing the cover in or out opens or closes the airflow. It has a baffle about 3/4 of the length just below the level of the exit pipe. We are experimenting with air injection on it to burn more completely, it seems to work, as there is hardly ever any ash to deal with. Its a steel pipe diameter about 20mm, which is open to air at the rear, low down on the back panel. This goes through the panel and up the rear inside the stove, then runs along just underneath the baffle plate almos the full length of the stove. The end is bloked, but there are dozens of wee holes drilled along its length (3mm holes iirc) This draws cold air from outside, heats it up and the air is forced downwards through the wee holes onto the flames. I dunno the full theory behind, he found it on the net again.

I have made a blockwork furnace in my garden to burn garden waste (a huge tree i cut recently) and i included water heating pipes into the furnace. I wasn't using the heat for heat so decided to heat water instead. It works quite well, but needs a bigger heat excahnger pipe network to be a bit more efficient.
I can hook it up to a kids paddling pool and warm the water in there quite nicely.
I want to get a hot tub (or a couple of old steel baths and make one) for the garden and would heat it with the furnace.
Will fish out a pic in a minute.

Would give out stupid amounts of heat ;D

Thats another idea I have, I am going to use one of those big black plastic barrels, about 600 gals I think. I also thought of using an old engine to heat the water, let the engine run and use its heat to warm the tub, it could also run an alternator or 3 to provide light ;D ;D
