Introduction: GAS TANK BBQ

About: I like to produce something and share, thanks a lot to instructables...

Hello my followers :)

As you can seen, my last project is a BBQ from "Gas Tank". I have spend 30 bucks for everything, include cutting disc etc..

İt works very efficient. I have used only wood for cooking although it cooks almost 4 hours.

Tools that I used:

- Two Angle grinder, for cutting and grinding

- Welding Machine

- Protective gloves

- Face protector shield

- Drill

Other Materials

- Gas Tank

- Square stick for grill

- Pipe and elbow pipe

Step 1: Begining of the Story

Gas tank which is we use it for our gas furnace.

Step 2: Cutting Off the Top and Bottom Parts

Step 3:

Step 4: Cut Off the Lid

Step 5: Welded Hinges

Step 6:

Step 7: Decorative Belt

Step 8:

Handle making from remains parts

Step 9:

Leg making from remain part.

Step 10:

Bottom plate for efficient air ventilation.

Step 11:

Grill is two piece, I have made it from 7mm square metal stick

Step 12:

Chimney process..

I have cutted the hole with angle grinder.

Step 13:

Handle making and last stage before painting.

    Güzel olmuş elinize sağlık. Aynı tüplerden 2 adet kullanarak, bende de roket soba yapmayı düşünüyorum.

    Be careful. All barrels are dangerous. Many years ago(as a young, perhaps a bit naive welder) I once used a water barrel(with water in it). as a welding table. Bad idea. As I struck the arc, the top blew off. The material I was welding hit my welding helmet and split it down the middle, fortunately with no damage to my face. The good thing....taught me a safety lesson that I carried with me throughout my 40 year welding career.

    I say again, please be carefull. ALL closed containers are dangerous when cutting, welding, etc. Filling only to where you are cutting is not good enough. If there is an air space, it may be filled with an explosive gas(even oxygen in the air). You must have water running through it, as well as the other precautions mentioned here. Will it explode every time? Perhaps not, but is it worth taking that chance with your life? I think not. Cutting, welding, drilling ANY tank is dangerous. Listen to the experts. Use every precaution, or better yet leave it to the professionals.

    What is the safety procedure that you would recommend? I would like to try this but I'm concerned about the safety of this project.

    Thanks in advance,


    You fill the empty cylinder with water and drain it. The entrapped combustible gases will be displaced totally. Then you can follow the standard procedures for cutting and welding.

    Thanks for your reply, I feel better about attempting it now : )

    Thank you very much. I had already bought the idea, hook, line & sinker and eager to go. But with your caution, hmn, I am thinking,not twice but probaly backing off or I'll just design and give it to a welder. Thanks

    coincido , si no inertizan el cilindro y todavía quedan residuos de gas se puede generar mezcla explosiva y detonar con el consiguiente daño para la persona que realiza la maniobra.

    Congratulations - great project. Some good thinking and problem solving.

    I am curious how you cleaned the gas bottle prior to manufacture - making sure any gas residue is absent. My biggest concern with using gas bottles.

    Thank you !

    When I bought it, it hadnt a valve also waiting maybe 1 month in this stuation. because of that I didnt clean the gas.

    all the hoopla about cutting a tank. Yeah, right. Fill the tank with water then cut it with what, an electric angle grinder - shocking idea. Fuel oxygen torch - nothing like getting scalded by super heated steam and boiling water.

    Put a pound of dry ice in the tank wait a bit and cut with whatever. The co2 displaces anything in the tank and doesn't support combustion. Not rocket science.

    i think you are suppose to drain the tank, then let it dry, unless, of course you want to boil water

    Well done !

    It's a good project to play with my new welding machine and my old and unused (empty) gas tank.

    Thanks for sharing !

    BTW: what kind of paint did you used ?

    Hi. Having built a fair few smokers, steam pots and BBGs... the type of paint SHOULD be stove paint... high temperature paint. That said I have found that virtually all commercially available ones are pretty rubbish. Hence why true stoves are made from cast iron. Most paints will rust up in a season and need to be refinished.
    All that said... I did make a steam pot that I wanted to last. I took it to a paint shop and they had it dipped. No idea what the stuff is but apparently it's pretty nasty and not good for home use... it has lasted 3 years though.
    Whatever you do... just make sure any galvanised finish is removed... it's highly toxic.
    All the rest of my stuff I just respray/paint once a year using big box store high temperature stove paint.
    Hope thst helps ☺

    Galvanizing is dipping into zinc, and it is toxic at higher temperatures. Muriatic acid, available from ACE Hardware for about $8/quart dissolves it in 30 seconds to a minute. Do this outside as the reaction gives off hydrogen gas and makes an acid mist. Coat the steel with oil right away as it will rust quickly.

    Also, fill with tank with water a couple of times to push out all gas. Let the tank air out too as a little gas can soak into the metal. I have known a couple of guys killed welding on "empty" oil field water tanks.

    Very slightly if at all. It depends on any rust inside, any coatings, any accumulated crud. A bit of airing out for a few minutes is insurance.

    Is galvanization a problem at cooking temperatures? Good question for the interwebs, I guess.
