Homemade Pressurized Alcohol Stove For Ultralight Backpacking
In the last few days I have been researching how to build a homemade alcohol stove out of pop cans for backpacking. I found directions for several different designs at zenstoves.net and decided to try making the pressurized type. Here are some specs and the pictures documenting the process.
Specs:
2 cups time to boil: ~5 minutes
time to prime: ~10 seconds
weight: < 1 ounce
capacity: 1.5 ounces
full capacity burn time: ~8 minutes
fuel used: denatured alcohol

The two cans that will eventually become my alcohol stove.

The three primary pieces to my alcohol stove. The top and bottom parts with the inner wall that helps hold it together.

A completed pressurized stove that burns denatured alcohol and weighs approximately ONE OUNCE! It has an inner wall, is approximately 35 mm tall and holds a little under two ounces of alcohol. I used jb weld to attach the bolt and nut, the fiberglass wick and the top and bottom pieces of the can. I finished it off with some paint that can handle temps up to 1200.
