I have been toying with alcohol stoves for many years now. For the most part I have stuck to others of others. Wile the designs of others have influenced this one greatly, I am calling this my own.
It is a pressurized stove that does not need a pot stand. It has a large fuel capacity for a long burn time but can be adjusted by simply using less full. It is more durable than most stoves if its type.
It is heavier and larger than a lot of alcohol stove designs.
This is a tutorial on making one with items I had on hand, not with the best tools for the job. This is just to help show the ease in building.
I selected the aluminum bottle from a venom energy drink. Any aluminum bottle shout work with this design, but I prefer venom. These have thicker walls than any beverage container that I have found. This make for a heavier stove than others out there, but it is much more durable. These bottles also work great as fuel containers. I chose not to remove the paint. I kinda like the way it looks with it, but simply sand it off if you wish.
The first thing is to get rid of the plastic ring around the neck. A dremel make quick work of this, but working without one, this is the hardest part. If you want a smaller stove, you can cut the neck off at the bottom of the plastic ring.
Cut the bottle in half with the top part a little longer.
I took my Leatherman's metal saw and cut flow ports to allow the fuel to pass from the fill chamber to the pressure chamber.
Invert the top and press into the bottom. Being that it does have thicker walls, it is a little harder, but there is almost not risk of splitting out the side. Using a board will help give you more control and protect yourself. Press till top is seated to the bottom. i used a board splint off the ambulance.
You cannot see it in the photos, but you will be able to see and feel where the shoulder of the top ans pressed out on the bottom. Move up about 1/4 inch and mark. Use tape or paper to mark a level line around the bottle at this point and trim to it as flat as possible. A saw will work, but scissors are easier to work with. The trauma shears I used made easy work of this. I then used the file from my leatherman to smooth and flatten the rim.
Here you can see the inside with drain ports at the bottom
Wrap a piece of paper around the stove and mark the diameter. Decide the spacing you what for you jets and mark. Reapply the paper and tape in place so the jets will about 1/4 inch below the shoulder mark. I had a EKG strip handy and it worked great as a template. I place my jets at a 1 cm interval.
I want my jets small. I did not have any drills with me, but I did have some expired IV catheters. I selected our smallest, 24 gauge, discarded the catheter and used the needle to drill. The 24 gauge has an IO of 0.02 mm so that is about the size of the jets.
That's that.
