DIY Wood Gasifier Camp Stove

This is a cheap and easy camp stove that can be made from things you normally throw away. This design can be carried in a backpack, produces enough heat to cook most things, leaves very little ash and burns with almost no smoke.

For this project you will need:

2 cans, one large, 4" diameter and one small, 3" diameter.

Drill, (Corded or cordless, it doesn't matter)

2 Drill bits, 3/16" and 3/8."

Sharpie marker.

File.

Tin snips.

Belt sander.

Soldering iron, blow torch, or other soldering tool. *Optional*

Solder. *Optional*

You will also need gloves and safety glasses, especially the gloves, because the edges of the cans are extremely sharp.

Trace the bottom of the small can onto the bottom of your large can, as shown. If the small can has a lip on the bottom, sand that off so it is flush with the sides of the can, but leave the lip on the top. Now, puncture the big can and cut on the line you drew. The small can should now slide into the large hole you just made, but the top lip should not slide through.

I hope you're in the mood for drilling, because you've got quite a bit to do! For starters, turn your small can upside down, so the closed end is facing up. Now, drill 3/16" holes all over it so the entire bottom is covered in them. Now, tip the can on its side, and drill a row of 3/8" holes around it on the bottom end. (See picture two.) Now, on the top end, drill a row of alternating holes, 3/16." (Picture three.) Now for your big can. For this can, simply drill a row of alternating 3/8" holes on the originally open end, NOT the end you cut out. (Picture four.) Now, slide the small can bottom first into the cut end of your large can. Your assembly should now look like this: The originally open end of the large can now sits on the ground with the alternating 3/8" holes just above ground level. The small can should be sitting upright inside the big can.

This step is optional. If you wish to make the assembly more durable, simply solder around the rim where the two cans meet. If you use a blowtorch or any other flame device for soldering, it is likely that the heat of the flame will burn the inner coating out of the small can, which will smell bad and look really awful (Okay, a bit of exaggeration there, but it will still give off black smoke and smell unpleasant) This is totally fine, and it won't last long. If you use a soldering iron, or choose to skip this step, it will happen on the first burn of this stove, which isn't a problem either.

To light the stove, simply fill it with small, dry sticks, and toss a match in. If you wish, a small amount of lighter fluid makes starting easier. I will show how to make a pot stand, and things to do with this in the future.

I hope you enjoyed this project! If you have any questions, please write them in the comments below
