intro: Gas Bottle Wood BurnerGas bottle wood burners are very easy to make, efficient, and are perfect for late night parties. If you turn them right up, the middle can start to glow red, you can put akettle on the top, or cut the top off and add a hot plate. These are really easy to make, and be changed however you want.
Please vote for me in the Keep Warm contest!

step 1: MaterialsYou will need:
-Gas Bottle (Large (47kg) or medium, but not the really small ones. The main image is a medium one.)
-A ~6 Inch Diameter Pipe 90 Degree Bend (I Used Lorry Exhaust)
-A length of ~6 Inch Diameter Pipe For Chimney (I Used Lorry Exhaust)
-Something For Handle, (I used two bolts welded together and a scrap piece of metal for latch)
-A Section Of Heavy Duty Hinge, Average Door Hinge Wont Be Strong Enough
-Box Section For Air Vent (~3 inch square for medium bottles, double for large bottles)
-Length Of Rod For Air Regulator (Optional, for damping fire down)
Tools:-Grinder-Welder-Hose Pipe

step 2: DrainUnscrew the gas valve in a ventilated open space, preferably outside, away form open flames and sparks.
Turn the bottle upside down, then wait for allot more gas to come out.
Wait until gas stops coming out, then unscrew the valve from the bottle, which requires allot of force, and probably a vice. A little more gas should come out.
Turn the right way up, then fill with water.
Leave the water in until you are ready to cut.
Bottle should now be gas free :)

step 3: PrepFirst, you will need to empty out the water, then cut the guard off of the top of the bottle, then grind the stubs left until its fairly flat.
Mark out where you want the door, about 6 inch from the bottom weld line for the fire base and big enough to put logs in.
mark a hole for the chimney on the opposite side from the door, just below the top weld line and just smaller than your chimney diameter (~5 1/2 inches).
You could have the chimney coming out of the top, but it is more efficient with it coming out of the back of the burner, as it heats the top of the bottle instead of goingstraight out the chimney.
Mark out a section for the Air Vent, Making sure the bottom weld line of the bottle is just below the top of the vent, about 1 inch off the bottom of the actual bottle.

step 4: DoorCarefully cut out where you have marked the door using an angle grinder.
Once cut, remove the section you have cut out, and position in the opening where the door should go.
Offer up the hinge, and test how the door opens. Move it until the door opens well, and doesn't catch too much on the bottle.
Once you have found the correct place, clamp the hinge to the door and weld it in place. You may need to remove the door from the opening to do this, so mark wherethe hinge is going on the door so you don't lose it's position.
With the hinge on the door, place the door back in the opening, and weld the other side of the hinge to the bottle, making sure the door will open and close withoutcatching too much.
Weld a section of steel, doesn't matter what size, to the other side of the door from the hinge, so that the door cannot go inside of the bottle.
For the latch, drill a hole through the scrap section of metal, and bolt to the door, with another bolt on the bottle for the metal to latch on to.The metal will need a section cut out so that it will latch onto the bolt. Then weld a bolt or other section of metal onto the middle of the latch, bend it 90 degrees, and thiswill be the handle.

step 5: ChimneyUsing an angle grinder, cut around the marked section for the chimney opening. keep the bit you cut out if you are going to make an air regulator.
Weld the 90 degree bend over the hole in the bottle, obviously pointing up towards the top of the bottle.
Weld the section of pipe for the chimney to the top of the 90 degree bend. This section should long enough to keep smoke out of your face but not so long the weightcaused to burner to fall over.

step 6: Air VentCut out the hole for the air vent using an angle grinder, make sure it is just bigger than the box section.
Slide the box section into the hole about 2 inches in, and weld in place. It should stick out about 4 inches.
For an optional air regulator, find a section of metal just big enough to rotate inside the box section.Drill a hole either side of the box section in the center.Push a section of bolt through, any rod will do.Weld the section onto the rod, so that it will rotate when the rod is turned.Bend one end of the rod 90 degrees so that it can be adjusted.Attach a stop onto one one one end of the rod so that the friction will hold the valve open.

step 7: Finishing offTo keep heat in, fill the hole where the valve was with weld.
If the gaps around the door are too large, attach a thin section of steel to the door like in the picture below, so that it covers the gap.

step 8: LightingTo light, you will need to lay down about a whole newspaper of screwed up paper, or just to the top of the air vent.
Light it, then whack on some small sticks to get the fire going.
Once the sticks have caught, put on small logs, and once they have started burning, place bigger logs on.
Once going well, the paint will turn black, and start pinging off in hot areas.

sensoryhouse says: Feb 5, 2009. 4:20 AM REPLYso i could use a compressor tank right?
chalky says: Feb 4, 2009. 3:58 PM REPLYthis is a brilliant idea,you could even weld a griddle type'o'thingy to the top so you could fry burgers/sausages lolEXCELLENT! i will try and make one for my garage

DrStoooopid says: Feb 4, 2009. 6:30 AM REPLY***SAFETY WARNING***
Propane will permeate the metal throughout years of use. It is EXTREMELY important than when you take the valve off an old propane bottle you let it sit forseveral days in the sun, to allow the propane that is attached to the metal to release and vent into the atmosphere. (remember Propane is heavier than air,so let it sit UPSIDE DOWN.)...also before you cut with a torch, it would be wise to purge the cylinder with argon or CO2. A Propane explosion is a very realconcern, and you do not want to get caught with your pants down.
Safety is very important when dealing with Propane. or Propane accessories.
technodude92 says: Feb 4, 2009. 1:26 PM REPLYWon't the water do the same thing as an argon/co2 purge? I think the water would be better even, because it is easy to tell the water level. not so withCO2 or argon. not to mention a helluva lot cheaper. Or will the water keep the propane from un-permeating(FIXME:need new word) the metal.
DrStoooopid says: Feb 4, 2009. 2:21 PM REPLYno, you put the CO2 and/or argon in the cylinder to prevent it from exploding while you're cutting on it. How're you going to use a torch on a cylinderfull of water?
Also you WANT the propane to seep out of the metal. That's why you have to give it time to air out.
awang8 says: Feb 1, 2009. 10:49 PM REPLYPretty cool, but I think it would be better to sand off the paint first and add a little sand at the bottom for ballast.
btop says: Feb 4, 2009. 1:08 PM REPLYThe bottle is quite heavy, it didn't need any ballast.
Holden_vy_s says: Feb 4, 2009. 4:19 AM REPLYWhy not attach a fan (an old hair dryer works wonders) to the vent and give it a bit of forced induction? Add some coal it there and you got yourself afurnace.
btop says: Feb 4, 2009. 1:07 PM REPLYSure, the compressor hose makes it roar when i shoved that int he air vent,
Esque says: Feb 2, 2009. 5:30 AM REPLYNicely done, I'll be building one of these soon :-)
Da_Fudge says: Jan 30, 2009. 7:36 PM REPLYWhat a great idea!!! Great welds there too!
btop says: Jan 31, 2009. 2:14 AM REPLYWow, thanks.
It was my first time as well.
Da_Fudge says: Feb 2, 2009. 2:01 AM REPLYNo problem.
I know how good it feels to get a positive comment on an instructable, so I give them when I see one!!!
Fudge.
martynbiker says: Feb 1, 2009. 4:45 PM REPLYgood instructable!!!!!.... just ONE safety point I would like to add,It may be a good idea to put some "legs" on the bottle and slant them out at 45 degrees to make it more stable as the pipe may make it 'top heavy' or moreprone to fall over ( dont ask me how i know.... but i will say picking one of these up after it falls over is a nightmare!)
mister fixit says: Jan 30, 2009. 9:15 PM REPLYthis is a good set of plans. Icould not find a gas bottle so i used a 40 gal. water heater. The water heater is made of thin boiler plate.It works good .

ehmbee says: Feb 1, 2009. 7:09 AM REPLYThe water heater makes a great burner-Mother Earth News has an old set of plansfrom the 70s if you wanted one and did not want to fly by the seat ofyour pants. It looks like you want to be pretty proficient with a welder and torch, however.
btop says: Jan 31, 2009. 2:15 AM REPLYCool, I find gas bottles are readily available to most people, and a company recently went bust in the UK so there is alot of bottles that cannot bereturned.
stephenniall says: Jan 31, 2009. 5:11 AM REPLYtut Me and my dad just got hold of a few gas bottles and was going to make these and post a instructable but you beat us lol
see-saw says: Jan 31, 2009. 3:34 AM REPLYHere's a pic of a UK gas bottle like the one used here.
BeanGolem says: Jan 30, 2009. 3:43 PM REPLYSafety tip:
Do not drink too heavily around these types of stoves, then trip, then try to catch yourself with the stove. Enjoy your fingertips.
Note: wasn't me.
btop says: Jan 31, 2009. 2:17 AM REPLYOuch.Sounds painful.They do get extremely hot, and if its dark it allot harder to see it as you cant see the flames. BE CAREFUL!
see-saw says: Jan 30, 2009. 5:34 PM (removed by community request)
see-saw says: Jan 30, 2009. 5:41 PM REPLYPS Thanks for this Instructable, I've been wanting to make a wood burner from a gas bottle for my workshop for weeks but couldn't find the right design.
Will have a go next weekend and post some pics.
btop says: Jan 31, 2009. 2:16 AM REPLYCheers for that, Ill try and get a photo of the bigger ones (47kg).
goodgnus says: Jan 30, 2009. 1:17 PM REPLYCan you please add a picture of a gas bottle prior to modification? Perhaps in Step 2? I would like to see the guard and tabs that need to be cut/ground off.Here in the U.S. I think we have different gas bottle designs as the gas bottles you're using don't look familiar to me. Thanks!
btop says: Jan 30, 2009. 1:39 PM REPLYI would, I haven't got one just now, ill try for this weekend.Cheers.

stone3408 says: Jan 30, 2009. 1:14 PM REPLYGreat job. Very cool. There have been a few of these posted before but, this is the most advanced on here that I have seen as far as air flow. I had a guy tellme that a 30 gallon water heater tank served this same purpose well.
