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.

Disclaimer: This project involves sharp tools, sharp pieces of metal, fuel, and fire.  I take no responsibility for any and all damage that you do by following these directions.  These instructions are for informational purposes only.  I disclaim all responsibility for damage or death to property, person or animal caused by either the correct or incorrect following of these instructions.  This project should only be attempted by a responsible adult, following proper fire safety protocols, and with an understanding of all the risks involved.

That said, let's get started!

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
<p>Okay, I'm doing this, but due to lack of materials and tools, I've had to make some substitutions and improvisations.</p><p>First, I had only one Lite Bottle to use, so I had one chance at this. I decided to use a trick from another video I watched where you use a can to slightly stretch another can. I found that typical soda cans are the same diameter of the Lite bottle, just not as thick. So I got a soda can, used it to stretch a second soda can and used that for the outside of this stove. I cut the second can with a LOT of room to fail, and slowly pounded the first can inside it, letting the force of the first can stretch the second, and then cut the hole in the bottom to accommodate the neck of the bottle. </p><p>I didn't have a compass or a spade drill bit, so I punched a hole in the center and &quot;winged it&quot; I slowly opened it up, cut more away and in some cases cut too much. I forced the outside down and adjusted and moved, cut more away with a skinning knife and just worked it on. I finally got it down and it's seated right. I trimmed the bottom down so that it was just 1/4 inch from where the inside neck transitions to the straight wall. Once I did that, I bent it in, to fuse them together and to lose the sharp edge.</p><p>THEN I realized I made a MASSIVE mistake. I had not put in the jet holes, and the outside wall was pushed too far down and too much of the threads were exposed. So, working with a pin, I managed to make the 8 jet holes in a different place. </p><p>Now, I am waiting to get a nut and a finger bolt so that I can put the fuel port on, I'm also going to put JB Weld on the seam around the neck and the bottom of the outside so I can fill all the gaps and make it airtight. I also plan to JB Weld the bottom section of the stove, where I bent it up. I found that it is NOT watertight, so the JB will fix that. </p><p>I can't get any additional aluminum from the store/hardware store, so I'm going to cut up a #10 soup can and use parts of it for the supports. That should allow me to have something that will work, and I might even be able to flange the metal a bit to make everything more stable.</p><p>Next time.... I WILL do this right. I note that the nut on the inside that Tetkoba recommends is not used for this tutorial, and I also note that it would be easier to drain the stove of unused fuel with the nut on the outside. Which makes things MUCH easier.</p>
What spade bit did you use?
Love it gonna give it a try once I reclaim my house from moving it
Tetkoba San is an artist when it comes to alcohol stoves and I really like what you have done but I'm slightly confused. <br> <br>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 &quot;An aluminum Coors Light bottle&quot;. <br> <br>Can you provide additional pictures that show this relationship with the seemingly two bottle bottoms? <br> <br>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.
