Here's the deal. I was impressed by the seemingly stronger structure of the aluminum beer bottle stove, so I made one.
It was some time later I started looking at what else I could do with the same bottle. So, without further a due, may I introduce...
The Bottle Neck Cap (BNC) Stove. I made it from the neck of the aluminum bottle and two bottle caps.
1)Take the leftover neck piece and fit it tightly with a cap. Make sure it doesn't leak, as this will be the base of the stove.
2)Take a second bottle cap, remove the gasket, and use a drill or push pin to place a single hole in the center. If you use a push pin, push from "inside" side of cap to "outside".
3)With the first bottle cap turned downward and the open portion of the neck upwards, place the second bottle cap upside down in the neck of the bottle.
4)Depending on how much neck material extends past the second cap, you may wish to trim it down (I'm still playing with this variable).
Place in a primer dish (just in case the bottom gasket starts to leak!).
Fill with approx 1/3 oz denatured alcohol, couple drops of primer. Light.
My original second cap did not have a fueling hole. Here, fuel was placed in the neck first, and then the second cap was gently placed in the neck.
The ridges of the second bottle cap act as jets as the stove comes up to tempurature. Which leads to another problem I'm having, in that after initial lighting, the stove tends to die down about 1:30 into the burn. Sometimes it comes back by itself, other times it requires a bit of a "tap" to wake up.
I was using a 12oz Heini can. I also didn't have a proper stand and was using the heavy cast ones from my kitchen stove, and no windscreen. I sure these two factors increased the time to boil by some amount. I also want to try some insulation to act as a wicking material.
Clear as mud? I'll try to take some pics tonight.
Use the preceding instructions at your own risk. Using denatured alcohol is extremely flamable and cause serious injury.
