I have to say, this thing was fun to make (a bit painstaking) and works great! Hardly efficient compared to more expensive stoves but great for the money! And I built it myself - ego... INFLATING....
I pretty much followed this tutorial: http://zenstoves.net/BasicTopBurner.htm (except my jets are on the side)
IMAGERY:
(Upper) Outer wall, with jet holes drilled (Like I said, my jets are on the wall of the can instead of the lip. Just personal preference, but in hindsight I won't be able to use the tutorial's "simmer attachment" to cover the jets up. I mostly just boil water for Mountain House meals and coffee anyway, so not an issue for me)
As the background suggests, I used a Dremel for some of the cutting (and grinding the edges of the hole in the middle of the stove), as well as simple scissors and an Xacto knife. I sanded the paint off the cans and smoothed edges with an SOS pad and some sandpaper.
Didn't have a hole-puncher handy, so my inner wall fuel ports are notches instead.
Slits measured out and cut, now the sides are joined to make the inner wall.
Outer wall resting on the inner wall, a perfect fit!
Upper, lower, inner, and some two-part epoxy ready to go!
With the easy part over, I then had to use a shim (sanded piece of Pepsi can as the tutorial suggested) to fit the upper and lower together without damaging the stove. It was a delicate process. Widening the upper portion of the can with a full can of Pepsi made it possible to fit these together perfectly.
VOILA!
Testing the stove (the tomato can was handy as I was using it to build the windscreen)
Also in this picture is the trial-run stove I put together first, just to build a little confidence in the concept and process. This stove's jets were on top.
The windscreen/pot stand, once four slots were cut in the bottom as air inlets.
This thing REALLY focuses the heat. It also does a great job of blocking even light wind which disturbs the stove.
I drilled four holes about 1.5" from the top of the can, parallel to each other, to stick two tent stakes into as a pot stand.
I use a space saver cup, the type that nests onto a Nalgene bottle, with this setup. The cup sits down inside of the windscreen and is about as efficient as I think this system can get. The cup nests on the nalgene and the nalgene nests in the windscreen, with stove and fuel, a lighter and the tent stakes.
My little corner of the house, where I'm in charge! Don't tell my wife I said that, please.
Overall, I'm very satisfied with how this stove turned out. It's a cool concept and cost almost nothing, assuming you already have the few tools required and a few cans of soda. I haven't timed it but I'd say it boils .5L of water in about 4/5 minutes with the windscreen stand. Never measured the amount of alcohol I put in it either, but I usually use probably around a 20/30mL squirt of denatured alcohol when I run the stove.
This thing is pretty sweet for short solo trips, and always is an attention getter/conversation starter. I'm thinking of trying a new stove build but haven't decided on a design. I have been thinking it would be cool to try a coil-jet type, though it wouldn't pack down as compact as this design.
Anyway, that's my stove! Thanks for checking it out.
I won't tell anyone,especially the navy..
