I was experimenting with ideas that would utilize the "Altoid" tin, I JB-Welded three of the 9MM cases (they were the best fit in the tin) one inside the center rear of the bottom, nearest the hinge, and one inside each of the corners on the side away from the hinge. Then, I cut a piece of steel screen to fit snugly around the cases, the object was to contain some "Perlite" (available from most plant stores) which is filling around the 9MM cases. It will hold a lot of either 70% Isopropyl Alcohol, or, in my case, Denatured Alcohol, available from any paint or hardware store. I got a piece of 1/4" aluminum "key" stock, and cut three pieces so that there was about 1/2" above the top of the tin. My guess is that you could reduce the weight a little by using recycled aluminum arrows, but not sure if strength would be equivalent, I stuck the key-stock inside the cases to use as legs, put about 1 1/2-2 ounces of alcohol into the Perlite and ignited it. It burns long enough to get a standard canteen cup 1/2 to 3/4 full of water hot enough to use for tea, or instant soup, but doesn't burn the Perlite, as it just performs as a wicking, to get the alcohol contained, rather than just burning it in the bottom of the tin.
The top picture shows the components;
I cut another lid to fit generally over the "fire pit," but you could also use a scrap of aluminum flashing, I use that as basically a temperature regulator, it can be pivoted on the left-hand "leg" and rotated to turn the flame up or down to either conserve the fuel or just simmer soup
The bottom is the the stove assembled
I used three legs, trial and error will determine your length for the legs, as different fuels will burn hotter or cooler, and also the size of the pot used, that way it will hold even if you cut the legs slightly off equal length, and it will stay steady with a Sierra cup
for a strength test I sat a 12" cast iron skillet on top, so it is pretty much capable of handling about any small cook-pot that you might have in your individual bug-out pack.
When it cools, in almost no time, the legs (key stock) can be pulled out of the shell cases, put on top of the screen, and the cover closed.
I can stick it, and several hours worth of alcohol, in the outer pocket of a fanny pack, and still have room for a 1911, and extra mags, on the inside.
As another option, Jack Daniels, or Vodka, can also be used as fuel.
I also have a couple of those swedish stoves, and I like them, as well, but like weapons, you can't have too many stoves, and one of those altoid tins will fit easily, even in my glove compartment on my 'wing. I have to make a couple for my truck and wife's car, as well.
