Introduction: Best Penny Stove With Built in Primer!!!
There are alot of stoves out there that have trouble priming them. This makes it so you don't have to throw gas on the ground or all over your stove. Here is what you'll need.
Step 1: Cutting the Bottom Can
Using a sharpie and a book or small box mark a line all the way around about an inch and half from the bottom of the can. This will be your cut line
There are many ways to cut the pop can. I prefer the stab and snip method. This involves piercing the can above the marked cut-line and then working your way down with scissors. Then you can cut along the with small scissors. I used the ones on my small gerber tool. A small leatherman would work too. You can cut it however you want though.
Step 2: Cutting and Drilling the Primer/Base
For this one get your tin can and open it....BUT WAIT!!! You have to turn you can opener sideways and cut the can open. This will leave the nice lip on it and give you and nice clean cut with no sharp edges. Be careful though while dishing up the content of the tin can as those edges remain sharp.
Clean it off and find the center of the lid. Mark it with a center punch to allow for drilling a hole for our low profile screw to go through. In my case I used a 3/16 drill bit. Drill the hole and clean up the burrs
Step 3: Flattening the Bottom Can
In order to join the bottom can with the base we must flatten the inside of the can. Look inside the can and you will see a convex shape. We need to flatten this out til the center will lay flat with the outside of the can. The round end of the handle of your screwdriver works well. I started pushing in the very center and with a circular motion worked my way around as I pushed the metal down. It helps to put the can on a hard flat surface. When finished the can should still sit flat on a level surface. Don't worry... if you push it too far you can always bend it back.
Step 4: Drilling in the Can and JB Weldling
Now its time to Drill into the bottom of the can. Take the can and line the bottom edge up with the tin can lid. The should be a raised circular lip about the same diameter of the bottom of the can. Line these up and mark on the can where you drilled your hole in step 2. This is where you will drill your hole. Use the same size drill bit as you did before. After drilling clean up the burrs
Now you can take your small nut, bolt , and washer and put it through the two holes you have made. Put the washer between the pop can and the nut on the inside. Make the two edges are lined up and then tighten it down very snugly.
We don't want our fuel to leak through the holes in the bottom so as a precaution I put some JB weld on the inside, over the nut, to prevent leaking.
Step 5: Top Can
Cut the top can in the same way you did before but make it a bit taller than you did before. I added about 1/4 in. I placed a small notebook under the box I used to make the first mark. Draw the line then Cut.
Step 6: Crimping, Insulation, Insertion
Crimp the edges of the top pop can all around the edges.This helps so the top can will fit inside the bottom.
Get the insulation and put it in the bottom can
Gently insert the the top into the bottom and make sure none of the crimped parts are splitting the bottom can.
Mark 16 evenly spaced holes around the outside edge of the can. Use a 1/16 drill bit.
Sand the outside and YOU ARE DONE!!!
