I was looking for a lightweight solution for a survival stove. I came across the SOLO Stove first and realized it was based on (or perhaps made by/licenced via) the Bushbuddy Stove. I was intrigued, so I made a test stove... (see image 1)

Worked great. Heated well, stayed lit for a while, but I noticed a few things. #1, it was flimsy. #2, it will rust easily. (tin rusts quickly once the protective layer is burned off).I decided to build a better one. I scoured kijiji and found a lady who had 4 stainless steel cannisters, and I found a stainless steel kitchen utensil holder at Wally-World. I used a small piece of expandable metal (used for doing stucco) for the interior ramp. (see Image 2) I tested it last night with a 4 inch long piece of pine tongue and groove. It was 4" long x 4" wide x 3/8" thick. I lit it with a firestarter (cotton ball soaked in vaseline). This VERY small piece of wood burned for 13 minutes and the coals were red hot for another 8 minutes! That is 21 minutes of burning from a very small piece of soft wood pine. It IS a bit heavier than the tin version but will last much much longer.

I used the cannister lid as the bottom. (see image 3) I left it on during the whole burn. It did not interfere with the fire/coals. In fact, it caught the small dropping embers and ash. The amount of ash left over was equal to the size and thickness of a nickel. pretty much nothing. Very efficient.

<p>The key to getting these to work well is very, very simple.<br><br>The inner part simply needs lots of small holes in the base made with a punch or sharp drill. Then around the edge very close to the top you can make much large holes with a 10mm drill bit or even snip them.<br><br>The idea is that the outer can allows air to feed in from the bottom but also some goes up the sides to enter at the top holes. This is where the air completes the combustion and creates the small jets of flame.<br><br>I found it is very tolerant of a varietyu of designs so just give it a go!!! </p>
<p>Looks nice, but I can't figure out , how the inner part is made from this photos. Can you please give a simple schema how to connect the parts.</p><p>Thanks</p>
<p>Here it is weighed</p>
Well done. Now if we can figure a way to fold it flat, to fit in a pack.
<p>Really nice! Looks like you're creating some sort of venturi effect where the air hits the burning embers at exactly the right place and speed to burn really efficiently. </p>
