This article is a step by step instructions with pictures on how to build this chimney stove. The light-weight stove is great for backpacking and winter camping. The long chimney makes this stove great in tents and snow shelters. The chimney can be taken apart for transportation.
Due to the small size, the heat source won't generate too much heat for small spaces.
The stove accepts a variety of fuel as heat source: wood sticks, coal, small tin can alcohol stoves, and candles, to name a few!
Use three empty, clean, cans.
You can use any size, but two of them have to be the same size, and the third with a slightly wider diameter.
The two cans of the same size will be cut differently.
We will call the chamber can "A", and the stove base/top "B", and the stove bottom/ash-catcher "C". Remove the paper from the cans
Work on the base/top first (can A).
Mark opposite ends for proper alignment of the big round cuts for the chamber part.
Align can B with one of the marks you made previously on can A.
Place it about a 1/4" from the top edge of can A, and use it as a guide and draw a circle around it.
When you draw the circle, draw it in such a shape that the can will fit through the hole, once the hole is cut.
Draw a similar circle on the opposite side, at the same distance from the top, as the first circle.
Make holes on top of can A, either using a thick nail, or you can drill the holes.
The purpose of the holes is to let more heat reach the stove top from the chamber
The stove top completed.
The reason not to remove the whole top is, that you can use smaller cups on the stove top.
Start cutting out the circles.
Use a thick nail, or drill, to get the cut started.
Cut out both circles.
You can use metal sheet cutters or a power tool for cutting.
I suggest you file or sandpaper all cut edges so they won't be sharp.
Place the chamber (B) through the holes in the base/stove top (A), as shown in the picture.
The chamber opening should be very close to the base/stove top, about 1/4".
That will give enough room for the chimney at the other end of the chamber.
Mark the edges on the outside bottom of the chamber, inside the base.
Separate the to pieces (A and B) again.
The marks you made in the previous step should look like in this picture.
|15|| Draw cut lines, the way it is the picture. |
Also, draw a small circle in the middle, roughly about 3/4" diameter.
The first cuts are to create stoppers to lock the to parts (A and B) together, and to create openings for ash to fall in the ash catcher.
The opening in the middle is also for ash to fall in the ash catcher.
|16|| Cut out the hole in the center, and along the cut lines you made. |
But do NOT cut along the first lines you made in steps 13 and 14!
The pictures in steps 18 and 19 show what it should look like when done.
|17||You are basically making "teeth" sticking out from the original lines you made in step 13 and 14.|
|18||Cutting completed. There is a hole in the middle, and a set of teeth sticking out from the two original lines.|
|19||Put the two pieces A and B together again, and bend the teeth you made, over, so the chamber locks into the base.|
|20|| Next, make the stove bottom / ash catcher. It has to have larger enough diameter so the stove base fits inside it. |
If the bottom is too tall, mark how much needs to be cut to make it fit.
|21|| Cut the bottom part to size. |
As earlier mentioned, file or sandpaper down any sharp edges.
|22|| This stove needs some kind of chimney, be it either a short or long one. |
I made mine of an old bath tub curtain rod.
If you don't have any pipe, you can roll a short chimney, using the material from another can.
|23|| Once you have a chimney, draw a circle on the top back of the stove chamber. |
Draw it the same diameter as the chimney
|24|| The circle for the chimney cut-out completed. |
Next, cut out the hole. Be careful you don't make it bigger than the chimney!
|25||Draw a small mark at the bottom of the chamber, opposite from the chimney hole.|
|26|| Cut a small hole at the mark from the previous step, same size and shape as the bottom end of the chimney. |
The bottom end of the chimney has to be shaped as shown in the picture in step 22.
That will ensure proper chimney function, and gives needed stability to the chimney.
|27||Insert the chimney in the chamber. It should fit snug, and there shouldn't be any large gaps between the chimney and the chamber, where the smoke could leak out.|
All done! Read on for more options!
|a||This chimney was designed to be stabilized by tying the top of the chimney to another structure|
|b||If you don't want to, or can't, support the stove with the chimney, you can build a support base for the rear of the stove. In this case, use a shorter chimney for better stability.|
|c||You can make a free-hanging lid for the stove opening. Make a small hole in the center of the lid for air intake. You can use a stick or other tool, inserted in the hole, to place or remove the lid on on/off the stove.|
|d1||The way the stove was designed, you can place a small alcohol stove or a candle inside the stove. If you want to use other fuel sotces such as wood sticks, make a grate that goeas above the ash catcher|
|d2||The grate for the ash catcher is made so its locks in place and is easily removed as needed.|
