This article will teach you how to make an inexpensive penny can stove yourself in less than an hour.
What you’ll need
- 2 aluminum cans
- A nail to puncture the cans
- A hammer
- Sanding block or file
- A marker
- Fiberglass insulation
- Two block of wood or books to mark your can
- Heat resistant Gasket sealant
- Mark and cut the cans
First off, mark the cans where you’re going to cut them, using the block of wood or book. Mark the first an inch off the bottom. Place the marker on the wood and then rotate the can so the marker makes an even line.
Repeat for the second can but with two blocks of wood or books to raise the height.
Well above the cutting line, punch a hole in one can and cut off the bottom part. Do it as close to the line as possible and keep cut even. Try not to dent the can.
Do the same for the second can. Discard their top parts. Trim out the sharp edges of the cans using a file.
- Making ventilation holes
Turn the larger can upside down and use a marker to make a hole right in the center of the underside. Then mark four more holes around it. For reference, you should be able to cover all of these with a penny, so don’t make the spacing too big.
Mark the outside rim, with 16 marks evenly spaced along the edge of the can. It is easier to do this halves and then in quarters and eights.
After that puncture the can at the marks using the nail and hammer or a punch! When using the hammer be careful not to dent or crush the can when you’re hitting it. Because these holes are the jets of the burner, don’t make them too large. The bigger they are, the faster the alcohol will burn.
- Fitting the two ends together
Using a pair of needle nose pliers, bend the edges of the shorter end. The two ends are of the same diameter. So you have to bend the edges in order to fit the shorter end inside the longer one. Now the two ends will fit together. Before you fit the two ends together, you have to pack fiberglass inside the longer end. This will be the filler that will later absorb the alcohol.
Now push the two ends together carefully. The less the cans bend, the better the ends will seal. This way you won’t have to use too much sealant. Make sure to seal the crevice between the two ends.
Now wait 24 hours before continuing.
- Adding fuel
Rubbing alcohol, denatured alcohol or HEET can be used to fuel the stove. Use the center holes to fill the stove and let it drain down the chamber. Once the stove is lit and burning, place a penny in the center so the 5 holes are covered. Now you have a fully working penny stove.
