In this Instructable, I will show you how to build one of the most efficient types of alcohol stoves: a self pressurizing, chimney-type stove.

Step 1: First Step - Gather Materials

First, you must gather all the necessary materials.  Most of these can be found at a hardware store like Home Depot or Lowes.  The stove itself is made from an Coors Light aluminum bottle can.  You will most likely want to get several of these, as it can be tricky to get this to work the first time.  The aluminum bottle design is also used by certain energy drinks like Monster.

You will need:
1. An aluminum Coors Light bottle
2. A pair of scisors
3. A center punch with a sharp point
4. A knife, razor blade or Xacto knife
5. A fine point marker
6. A 1 1/2 inch spade bit
7. A pin vice or a small drill like a Dremel
8. A 1/32" drill bit
9. Steel wool, both fine and coarse
10. JB Weld - I use JB KwikWeld because it sets up faster
11. A ruler or a square
12. Not pictured - needle nosed pliers and nippers/angle cutters

13. Optional - A pair of calipers can sometimes be handy for checking exact measurements
What spade bit did you use?

Tetkoba San is an artist when it comes to alcohol stoves and I really like what you have done but I'm slightly confused.

I follow you pretty well but I seem to get confused with the image on the far right of step 3. It seems that this is the bottom of another bottle, but in your directions you say that we just need 1 or "An aluminum Coors Light bottle".

Can you provide additional pictures that show this relationship with the seemingly two bottle bottoms?

Thanks!
Tetkoba is stellar at doing alcohol stoves!. good job at finding a way to adapt it to what we have here in North America. It looks good but the flame does seem to pulse quite a bit, Have you done a boil test yet?

Yeah I have, but haven't filmed them yet. This weekend, I plan on doing real world boil tests, while on a backpacking trip. I'll try to take some film, record some data, and report back.

Intresting, It lit from the inside and looks like the fire even breath.
