Woodstove Answered

I have built this woodstove for my tiny house. I had tight space limitations.
I chose a used 20 gal+/- propane tank. I cut out a door and exhaust opening with a disc on my angle grinder.
Helpful hint. I attached hinges befor making the last cut on the door. It lines up perfectly.
I found a piece of 6" well casing for my stack. An old piece of sheet steel for the top, in which I cut a 4" hole for my flue.
I am using the tank upsied down as I am using the original valve opening, which is 3/4" pipe thread for outside combustion air.
I welded the tank onto a 15" used steel car wheel for a sturdy stand.
I will not be burning wood only manufactured logs like from Tractor Supply and will be making used paper for making presed pulp logs.
I am letting the High Heat paint fumes air off before I fire it up. I also have a CO and Smoke Detector plus a Fire Extinguisher.
There is a dampner in the flue and a thru wall fixture. It is mostly airtight. I installed 1/8" flanges on in and outside of the door.
Used  a black wrought iron gate latch for a closer and some brass machine screws for bling. lol
If anyone does this make sure you know what the hell you are doing, if not don't try this at home.


I made something similar a few years ago. I don't have any welding gear, nor a tame student who happens to be a champion welder, so I fixed the flue (bought from Machine Mart) in place using fire cement, which worked fine. It hasn't come loose even though I stuff brushes up it once a year to sweep the chimney. You can't see the flue in the photo, unfortunately, it's hidden by the fireplace canopy. But this is proof that you can make one of these gas cylinder stoves with nothing more sophisticated than an angle grinder and a drill.

Mine relies on the gaps around the doors for combustion air. It's not the most efficient device, but it's better than an open fire and efficiency isn't too much of an issue if you have a free supply of wood.


Great job. I was fortunate to have someone to weld. I just can't weld anymore, it is so bright that I can't see the bead. Just old eyes I guess. Thanks for the pics. I love innovative people. Cheers

No offense but why the hell do you post it here instead of making an Instructable out of it?
You got all the nice pics, just put some explaining text together and make it right ;)
Two hints for future reference:
a) It really pays off to weld metal strips on the inside of the door hole.
This way the door will sit flush against them and the airflow is reduced.
I don't really like it when a lot of air is added through the gaps around a door as everything burns too fast and hot.
b) Instead of paint you can heat the thing up to max (outside please) and season it with oil like done for the old cast iron cookware.
Gives a nice black finnish and is mostly non stick.
Plus it prevents rust same way or better than paint.

But I like the idea, how you made it and how it is presented, so please make an Ible out if it!

The door is sealed with strips to make it airtight, some pics are before this accomplished. This is my first attempt at even posting on Instructables. So I will attempt to publish. Thanks for feedback.


Don't try, just do it ;)
Arrange the pics in a nice way, add the right text to it and provide detailed info on how to make that oven.
If you dare add some extra info on possible modifications and extras you used - like those door strips and how to close the flue for the right airflow.
To get noticed make sure to use a really catching pic for the title - in many cases the pic here decides if someone bothers to look further ;)

P.S. It took me about a year, scrounging for parts and deals. I would say that I have between $100 & $125 in it.


This is the air vent for outside combustion air. This was the top where valve was, now bottom of stove. This is threaded 3/4" AST pipe thread. Inside is a close nipple with a tee and 2- 2" nipples under fire.


That is one beautiful weld on the top of the tank!

That was done by a Payson High School student in the FFA program. He won best welder in Arizona for obvious reasons.

This looks really good!

I'd suggestion putting all this info together into an actual instructable. If you click "Publish" at the top of the page and then "New Instructable", that will take you to the instructable editor here https://www.instructables.com/editInstructable/ .

You can put your photos into various steps and add a bit of text, and you'll be ready to publish it.

I hope you'll consider it! :)

Thanks, I will try to get it published. I just don't think that I took enough pics early on.
