Firstly i would like to warn everyone that cutting gas bottles can be dangerous and i don`t take any responsibility for anyone harming themselves.
I like the ozpig type heaters but i couldn`t afford to buy one and i had a lot of bits in the shed so i thought i would give it a crack.
First up was to make the bottle safe to cut, this is what i did.
1. find a empty old out of date bottle.
2. open the gas valve and air it out for a day.
3. remove the valve and fill the bottle with water to purge all the gas out and leave full for a day.
4. tip water out and leave upside down for a couple of days.
5. fill with water and cut the top ring off and cut the door out.

I put the hinge on before i fully cut the doorout so it would still line up ok.

I used some angleiron offcuts to make the hotplate frame.

I cut the top out of the bottle before welding the angleiron on and
made a flue out of some 90mm shs and added some sleeves to take the legs.

Then i gave it a run tonight to burn the paint off. It worked a treat.
I still have to fit a latch on the door, cut the flue down and add a longer removeable section,
finish welding the leg sleeves on and give it a paint of pot belly black.

Pretty happy with the result so far and it should get some use at home under the pergola and if we go away in the van where they allow fires.
So far i have only had to pay for some cut off disks and some welding rods.

Nice Job, I was lucky enough to buy an ozpig second hand, but have become to love when camping. Hope you have as much happiness.

Brilliant, I always wondered why you fellas hung onto every bit of leftover stuff 'just in case'. Now I know :tickled_pink:. Might have to get MM to have another look at that almost empty, old gas bottle we have :cool: Cool!

Great job, and good safety tips at the start.
I particularly like your idea of welding the hinge in place before doing the final cut of the door. Good thinking.
So, have you worked out a suitable storage place in the 17?

Yeah I think it will go in the back of the ute. My dad has something similar and carries it it a heavy duty plastic crate so I will probably do the same.

Cooked up a batch of pumpkin soup tonight on the pig, worked a treat even if it was only about 3 degrees outside. Had to dry the wood too.

Very nice. Although I reacon the front door to the pig should stay open. My father has one of those puppies and the best place to sit around it is right in front of the open door. Toastie warm. :)

Looks Great, I would like to make one but don't have welding gear anymore. Checked online, $330 but I'm sure I can get someone to knock one up for universal currency - slab of beer. Do you need to use a class 1 or 2 bottle?

That's fantastic, you've inspired me to make one of my own
That's good to hear Adam make sure you show us! I hope to finish mine next weekend I have to cut the flue down and sleeve it to make it more portable and paint it.

Not sure on what class Macca just any out of date bottle. I thought a plumber would have all the welding gear.;)

Yeh, I sort of have, recently returned my bottles and the type of stuff I do I don't need them anymore. Welding copper even is nearly a thing of the past.

Hey Matt, I was thinking about using thin walled round steel spouting for the flue, any thoughts on that?
