Step 3: Cut Main Opening in Can Bottom

Cut the main opening by cutting out the center of the bottom of the can using an x-acto knife. 

Hint: Go over the area with the knife a few times before cutting all of the way through.
<p>I have been meaning to make one of these for some time. I modified mine a little, and only used one can - it was all I had, and I was also lacking patience! It turned out well, but I made the slot in the inner ring too small, so it takes a fair time to prime (around 20 seconds) and therefore I am burning more fuel on the front end. Once it was up an running, it burn really well and boiled a cup of water in a little over one min. Funny thing was, I went to snuff it and realized I couldn't cover the little holes with a flat plate (of course not!) and I had some excitement for a moment or two. </p><p>So I then made a simple cozy for it out of aluminium foil, which slips nicely over it and acts a a little storage cap for it as well. </p><p>I look forward to doing a neater job on the next one, using two cans, and burning a cleaner fuel.</p><p>Cheers!</p><p>P.s - I also didn't have any rubbing alcohol, so I used my wife's shellac nail polish remover. Big mistake! Boy that stuff stinks, burns super dirty and leave a residue on the stove and anything the flame touches! Don't do it! :) LOL</p>
<p>Now this looks professional and safer than most I've seen. I am encouraged to make this one. I would have liked to se a picture of it in use with how to use fuel ratio.</p>
<p>This is the one I made using the directions here. <br><br>This was made with a crappy paring knife (that I had to keep sharpening over and over again), a ruler, a drill, and the scissors in a cheap knock-off Swiss Army Knife wannabe.<br><br>I used improvised tools, didn't come out as nice as I wanted it to...but it worked and worked well. <br><br>This is a good set of instructions. I followed them to the best of my ability with the tools I had at hand and the final result was something that worked as advertised. I can't wait to see what I could produce following them when I break out my dremel tool and cylinder cutting jig. </p>
<p>I've made four different alcohol stoves based on different instructables, and this is by far my favorite. The others are harder to light, requiring you to hold a flame to the outside of the can to get the alcohol hot enough to produce fumes. After testing them all out, I threw the others away and am now making a bunch of this version to give to my family and friends for their camping packs and bug out bags. Excellent instructable!</p>
AWSOME could save some ones life
great, it looks like a trangia burner, but much cheaper. tony
Side note, especially about the 'Open flame during use will be hot' statement, Imagine, hot enough to melt the aluminum itself! I put one of these inside an old Sterno stove frame, and put the disc I scored out of the 2nd can bottom, on top.. Within a minute, the piece which was about only an inch from the top of the cans, melted and fell into the center well.. so yes, it DOES produce enough heat!
nice finished look for something made out of trash. We are ready for the post nuclear apocalypse lifestyle!
Actually, I had mine ready to go when Hurricane Sandy blew through New England.. Thankfully, never needed them.. but the southern sections got hit pretty good.
Great! if you did this with a couple of Fosters cans or even bigger two hieneken mini kegs, wow this is complety scale able.
I did the same with a pair of &quot;Steel Reserve&quot; cans someone dumped near a bridge riser, (while out Geocache hunting.) The only drawback, is it doesn't really add more heat.. But it is still do-able. I still can't quite perfect it enough to post, but the soda/beer can size is possible with just a single can, simply scoring out the center disc of the top.. I imagine the Foster's can version would be about the size of a standard marine alcohol stove. <br>
I can't quite get a clean-cut on the prototypes I've been trying to make, but the whole can stove with the open top, can also be made with just a single can, by cutting the top end about the same distance as from the bottom, but carefully using a knife point to score along the inside of the top, inside the flat with the opening, and using a strip of the can side not used, as the catalyst. (to carry heat from the top, down into the alcohol.) It's the scoring part that I keep mucking up.. sometimes too much, sometimes too little, and it ends-up tearing, which pretty much ruins the end to be pushed into.. But, just scoring the inside of the top, inside the center rib, does work just as well as using a 2nd can bottom. <br>
by far the best out there nice ible <br>
Great work!!! Best design out there!
works well thank you :)
This is the first &quot;can stove&quot; that I felt I could effectively build/use. Great design! I haven't tested it yet, I'll have to do that in a little bit. But here's a pic!
Thanks. Looks good
