I had the day to kill, so I figured why not.
A couple of years ago, I bought these 2 pieces of sheet metal for something (can't remember what), but I never ended up using them. So today I decided to turn them into a little wood travel stove.
First, let me handout an automatic "cool story, bro" to anyone who decides to comment on my obviously shitty welding skills. Somebody with my level of welding skill using 22 gauge sheet metal with flux-core wire is a recipe for disaster. I admit, it's fucking ugly, but it works (I think, haven't actually fired it up yet).
Total cost? Maybe $10 for the sheet metal I already had, $5 worth of wire, $3 worth of paint and a couple hours of my time.
Just because I welded mine does not mean you need a welder to make your own. I could have just as easily have done this with a hacksaw and a hand drill and just bolted the sides together.
Anyways, here's how to build one:
Start with 2 sheets of sheet metal. You can see the cut lines I've drawn on mine.Cut the pieces up. I used a grinder with a cutting disk, but a hacksaw would work just as well.The 4 long strips you see were cut so that I could bend them in half and weld them onto the corners for added strength. I only had a hammer and vice to do the bending, and they didn't turn out as straight as I was hoping.Here it is all tacked together:Next I turned up the heat and cut some air holes in the side and bottomOil jug simulates a potI ground some of the crap off, finished welding it as best I could and sprayed it with a can of BBQ flat black paint I had lying aroundIt weighs about a pound all said and done and will support my weight when I stand on it (250lbs), so it's fairly strong.
I think if I were to make another, I would use thicker steel (maybe 1/8") so that I could get better welds and actually get it square(er) then it is. If I'm not working tomorrow, I'll throw an old pot on it with some water and see if it actually boils it.
