Pocket Sized Camp Stove (The Improved "Penny Stove")
introPocket Sized Camp Stove (The Improved "Penny Stove")
NOTE: A lot of work has gone into this instructable. If you appreciate it, please rate it!
This instructable actually came about through necessity. I love camping, and often go hiking in the woods. How often have you spent a day fishing, and wished you could throw some fresh fish into a pan right there on the dock?
For me, this always meant carrying a bulky, expensive kerosene or propane stove which themselves can be something of a pain to get warm enough to use.
There are numerous instructables here on how to make a "Penny Stove." However, there are a series of problems with the Penny Stove concept that need to be addressed. For instance:
1.) You cannot put a large pot on a penny stove without crushing it.
2.) Penny Stoves get very hot, so must be placed on something that will not burn to be used.
3.) Putting a Penny Stove in your pocket or backpack for a hike, it will get crushed fairly quickly.
4.) Penny Stoves are either difficult to light, or do not conserve fuel well.
5.) Penny Stoves are easily blown out in the wind.
As for the commercial "camp" stoves, the *only* ones I've found are either glorified penny stoves (with all the same problems) or require you to carry bulky, heavy, expensive canisters of propane or butane. (Or a mix of the two.) I never did get the point of spending $50 for a "3 oz stove" only to have to carry a 13 oz canister to use it for 1 hour.
All of these issues have been addressed with the new and improved "Penny Stove" or as I like to call it, the "Pocket Sized Camp Stove." I do honestly prefer this over any commercial stove I've yet seen (and I've seen a lot). Better still, it was free. Even a cheap commercial camp stove starts at $30 and goes up quickly from there. I've seen less useful stoves selling for over $100. Considering that commercial stove fuel is also more than twice as expensive as denatured alcohol (calculated by burn time) and harder to come by, there's just simply no reason for me to purchase anything commercial.
While this isn't the size of an Altoids tin, and won't fit in your hip pocket, it will easily carry in a cargo pocket, or in the pocket of your backpack. I keep it in one of the smaller pockets of my ruck sack whenever I go hiking.
For $1.25, you can get a bottle of HEET, and numerous other fuels are even cheaper. (Though I'll tell you from experience, you'll get odd looks buying half a dozen bottles in the middle of the summer. I think the guy thought I was cooking meth.)
Compare this to the Esbit Stove that takes solid state tablets that burn (realistically) for approximately 10 minutes at $0.50 a piece. That's $3/hr, and it's not easy to come by.
While I haven't tested it, I'm pretty sure a $1.25 bottle of HEET (that can be picked up nearly anywhere, including gas stations) lasts me more than an hour.
My preferred fuel is Denatured Alcohol. (See the "Fuel" step.)
Finally, the problem I've had with solid state fuels is the time it takes them to heat up, the amount of heat they put out, and the amount of time it takes to put them away. This stove is ready to go in 1 minute, can be extinguished by blowing it out, or putting the measuring cup over it, and cools off in less than 3 minutes.
For a quick stop to fry up some lunch, this is my stove of choice.
If anyone has suggestions for improvements, I'm all ears.

step 1WARNING!!!
I want to make it clear that Penny Stoves CAN detonate. This is not a minor warning, but a very serious one. Unless you take certain precautions, you *can* actually cause…

step 2Required Materials
What you will need for this is the following:Two (2) aluminum soda cans to make a very standard "Penny Stove"Two (2) wire hangers (enamel finished, not the plastic covered …

step 3Optional Materials
JB Stik Weld is also an epoxy, but in a thicker, putty format. I would strongly recommend using this as well, although for the patient individual, it *is* possible to use …

step 4Required Tools
The tools shown in the image are pretty much needed for this instructable. I know not everyone owns a Dremel, but I can't stress enough just how much any hobbiest needs on…

step 5Optional Tools
While you can get away with using your wire snips and Dremel to prep the Penny Stove's top, I find it's much easier to use some heavy duty scissors and a hole punch. Note …

step 6Fuel
There are a number of fuels that can be used in these stoves, but they are specifically designed to use alcohol based fuels. The most common fuels seen are:"Heet" Gas-Line …

step 7Making the Penny Stove
Penny Stoves have been covered in length on this site, but I will go through the simple steps used to make the one I use for my own stove. Many cans were sacrificed to det…

step 8Making the Penny Stove (Cutting the Pieces)
1.) Using the razor blade rig (Image 1), score both cans approximately 1.5" from the bottom. Note that the score line does not have to be particularly deep, as it's just a…

step 9Making the Penny Stove (Prepping the Parts)
1.) Scoring the stove will cause the can to slightly bend "inward" where it was cut. While this is desirable for the top of the stove, you'll want to "stretch out" the ope…

step 10Making the Penny Stove (Final Steps)
The assembly of the stove is by far the most delicate step in the instructable. Be very careful here.1.) Slide the top into the bottom piece. (Image 1)2.) Very, very caref…

step 11Making the Measuring Cup
The measuring cup is made out of the "small" tin can and is approximately the same size as the penny stove itself. 1.) There's no need to be too exacting here. Just set t…

step 12Make the Rack Pins
The rack pins are fairly simple. Take a straight piece of hanger wire and bend a hook into it as shown. The length of the pin should be approximately 1/2" (~13 mm) taller…

step 13Making the Wind Guard
The Wind Guard serves two purposes. It will not only protect the stove from light winds when outdoors, but it will also help channel the heat upwards. This means more eff…

step 14Creating the Base/Lid
The Base will also double as the lid for the stove.The Base will allow you to use the stove on surfaces that would otherwise burn. It only ever gets lukewarm to the touch,…

step 15Making the Pot Rack
The Pot Rack will enable you to put much larger pots and pans on your stove, making it functional for much more than just heating coffee. Between this, a mess kit, and som…

step 16Assembly (Packed)
When you're ready to put your stove in your pack, this is how it's assembled:1.) Put your rack pins into the lid (Image 1)2.) Put your measuring cup into the lid, and put i…

step 17Usage (Video)
1.) Remove rack from around stove.2.) Remove lid/base, and empty contents (rack pins).3.) Place lid/base upright on stable surface.4.) Remove fuel cup and set aside.5.) Rem…

step 18Specs
After much experimentation, it was determined that for this particular design, the most efficient stove is one with 8 evenly spaced "thumbtack" sized holes. Even spacing i…
