Picture of Wood stove made from scrap
DSCN2119 (Large).JPG

My plan was to make a better furnace for melting aluminium but debating this with my wife she made a good point of how many time I would use the furnace Vs how many time we will sit out on a cold afternoon in the garden with a worm wooden stove.
So the wooden stove was the winner.

In this instructable I will show you how I made it all from recycled scraps at minimum cost. The total I think was 20 bucks. The only spend was on grinder discs, welding electrods and a special stove paint although you can save on that to if you don't wish to paint it.

Yesterday we used the stove first time and we sat beside it for over 3 hours and it kept us warm. The only thing I will have to change is to a bigger flue pipe but other then that its a super success.


Safety disclaimer : When using electric tools: welding, cutting, grinding always use ears and eye protection. Keep body parts away from sharp blades and always use full body protection gear.

If you don't know what you are doing take it to a professional. Misuse of pressured gas cylinders can cause injury and even fatalities.
This is not an instruction or a guide how to do it, I am sharing with you how I used a gas cylinder based on my own experience and knowledge.
Anyone who attempts this he/she will do it on their own risk,  I will not be liable for any injuries in anyway.
                                                                          WORK SAFE!

Nice stove!! Great instructable thanks!!
P. S... I just ran to check if any of the multimeters I have take temperature!!! Not one I was bummed!!
JKPieGuy4 months ago

Woah, you Multimeter can check temperature? I've never seen that honestly. Very cool, just as cool, or should I say as "hot" as the stove! (Haha bad pun.)

Looks great and I've seen a few by now shall we say. Had exactly the same issue as you on my first build, chimney to small - I never consider less than 4" tube for a chimney and much prefer 5". I also love the way your hinge stands out from the body so the door opens out and away much more, might have to borrow that idea Tbh. I did a slightly different thing with my hotplate as can be seen at http://halftroll-metalmadness.blogspot.co.uk/. Keep up the great work. Halftroll :)

I'll stick with your original design, I need the cooking surface, and the smaller pipe was so much cuter.
Melia Esperas10 months ago
I love your door, it's very close to the look I want for my stove, reminds me of small the cast iron stove in my grandmothers house.

Absolutely brilliant. I can't wait to get some welding equipment and do something like this!

It's on the list now!

would a old propane tank work?

A propane tank would probably work. Propane tanks can be dangerous even if you think they are empty. If you don't know what you're doing, you can get the valve removed at a propane tank service center. You are responsible for not blowing yourself up.

If you are going to cut or weld the tank make sure you have removed the valve, and removed any trace of propane and or oil that might be in the tank.

REMEMBER: Better Safe than Dead!
yeah i planed on being safe the valve has been removed for years my dad was planning on useing it in a project and had the valve remove when he worked at a place that filed tanks and he never got around to it so it has sat beside our house for like 5 years without a valve and i still plan on filling it with water for the postive displacment just to be absuteletly positive
Here in the Philippines, welders usually have exhaust gases from a vehicle into the tank so that it will be filled with the gases from combustion and will have no oxygen. We do that when we have to do welding on gas tanks and we do not have equipment to get the tank cleaned up and have to do the job in a hurry. Just be sure to do it for at least 15 to 20 minutes minimum..
Excellent ingenuity!
you have to keep te litlow cheminey beaucause smoke is like wood you keeping smoke and burn it
Damn. Seeing this I wish I wasn't a student anymore and had the room for such a wood stove. Definitely making one as soon as I have the space for using it.

Good job,this is now in my top 50 favorites on here,I think Ill try this one,I made a smoker from a clay pot that I saw on here last year and it turned out well,I hope this one does as well,thanks.

re; working on propane tank...saw very nice stove i n a dome house made from
around ball shaped tank. his secret for safety....DRY ICE broken into small enough pieces to fit into tank valve. he used about 2-3 pounds..the ice creates a
positive pressure in the tank forcing out the fumes and oxygen and displacing it
with low pressure co2. ihave not tried this yet as i havent found pretty tank yet.
very good instruct....thanks

you could have used the handle that you cut off of it in the first place
MPierce942 years ago
I was looking around for welding projects and this is one of the neatest ive seen! I have a few questions about some of the materials you used: First, can you tell me what capacity the gas cylinder you used was (lbs.). Second, what kind of barbecue did you get the base from? Any information you give me would be greatly appreciated.
SIRJAMES093 years ago
CAN WE SAY STUPID?? I think we can....
not you, but the guy using a power saw to cut that tank without protective gear.
that was an accident looking for a place to happen.

Getting back to the instructable.
I like how you stress safety, & how you went above & beyond what most people would do to make sure you work safe. Nice. Very nice. 8=D

Very nice, but it seems me known. Is this an old instructable, renewed?
NutandBolt (author)  rimar20003 years ago
I only wanted to add one more step as for the chimeny part in addition. Not realy renewed ible ;-)

I was thinking "exhaust pipe from 1/2 ton truck" for the flue...
groovy3 years ago
just wondering if you get enough air flow with the small inlet holes?
by the way nice build...
NutandBolt (author)  groovy3 years ago
Thank you, I don't realy have a use for the inlet holes because I leave the stove door semi-open. In retrospect I would do the inlet holes bigger or perhaps just one large hole.

Excellent instructable. Very well thought out. Great details. It was a very enjoyable read. Thank you for taking the time to record and post your information.
NutandBolt (author)  steppapajon3 years ago
Thank you for your comment, I am happy you liked it ;-)

Nice, did you have ti tickle a bit off your welds to get it to shut tight?
NutandBolt (author)  pdtnc4 years ago
Thanks, Very light grinding over the welds, the angle grinder cutting leavs a few MM gap (blade thickness) so the welds fits nicley .

Since you still have some square tubing, add two more flue pipes on each side of the current one. The three would look pretty cool, provide enough draft,and look something like a smokeing pipe organ!
NutandBolt (author)  flamerider4 years ago
I was thinking the exact same thing too, adding a few more square tubing in some interesting formation, the only thing Is I am not sure It will be big enough to suck all the smoke out. I am still searching for some decent size scrap metal for flue pipe, just something that will be in wider diameter. Smoking pipe organ, I like that is a cool idea :-)
ease dropping.

That is really nice. Thank you. Tip for all members here for welding cast iron. Preheat the whole cast iron piece in a oven to 400-500 F or higher ; also heat up sand with it. This will prevent the cast iron from stressing to much because of heat difference. Also it will take the weld much better. Do not use a torch to preheat the piece, this would cause hot and cold spots and will stress the cast iron. If welding, do not put the cast iron piece on a cold surface if possible. Weld the hot cast iron piece as needed, then take the hot cast iron piece and cover it completely with the hot sand. Let all of it sit until completely cooled down, this will prevent hair cracks that could turn unto bigger cracks. It has to cool down slow. Do not speed up the cooling, that's why the cast iron peace is covered up with hot sand. Hope this helps.
NutandBolt (author)  shortw4 years ago
Thank you very much for this info, I always wanted to know a bit more about cast iron welding when I did a few jobs working with cast iron. I noticed that cast iron reacts different where it was welded over the long term. The tips you gave are very good thank you again :-)
Your welcome. First when I came across this, was years ago when I went for a automotive school at a community college. We had a engine block and it had a big deep and long crack. We took it next door to get it welded. Welding cast iron? I replied... So ....I was glad to see how it was done. That welding instructor was 65 years old at that time and done welding all his life. I am a maintenance man now and when we weld a piece of cast Iron we set the piece to be welded on top of our big boiler ( very...very...very..hot..) for about 1 -2 hours to heat it up. Those welds usual last years in the factory settings. In your project it would not take long to heat it up in the oven and I would use the highest temperature setting. Note: I am a fan on wood-stoves. Most folks think that the metal on a wood-stove has to be thick. I have seen home made and factory made wood stoves in action with very thick metal and the heat output is very little because of the thick metal. The wood stoves with thin metal have a much higher heat output and therefore use less wood to get the same result.

hey Thanks for good idea. After i looked this i started to call around of finland to find cotainers and only few calls later i did get realy good deal 5 cylinders for 25€. We have recycling policy in here so can't find cylinders on sea or woods (it is actually good thing) bu now i can try to make few of my own so thans again and be warm on your garden :)
NutandBolt (author)  Soulis4 years ago
That sounds great I love bargains too, if you do make them please post a few images. Thanks :-)

Now THIS is a project that makes PERFECT sense!! If need be one could even use this when you go camping. A coil around the exhaust, coupled to some water reservoir - hot (or maybe at least WARM) water on the go? Thanks - well thought out and even better done!
NutandBolt (author)  hsahrc4 years ago
Thank you for your positive comment :-)

I suggest using a, for lack of a better word, "coil" type handle. It diffuses the heat very efficiently and could be easy to to make from an old spring. An example is a slag shipping hammer like the one from here: http://www.clovisusd.k12.ca.us/agcenter/Folders/Ag%20Ed/Faculty/Actis/Class%20Lessons/Tool%20ID/Tool%20ID%20Book/Individual%20Tool%20Pictures/welding/ChippingHammer.jpg
NutandBolt (author)  Mig Welder4 years ago
That's a great idea for a handle, I learned here something new regarding the coil diffusing the heat. Thank you :-)

Be careful if welding steel to cast iron. It makes for a poor  joint. However, if the joint won't be under excessive mechanical stress, it should be fine.

Anyway, I really like your instructable. Well thought out, very well explained etc. I love the concept of taking something old and discarded and making it into something new and useful. I also love it when the new and useful object is aesthetically pleasing too. 

Keep it up!
