How to make a Pressurized Alcohol Stove out of soda cans

http://www.leoda.us/projects.html Video of a Pressurized Alcohol Stove I made. Many videos on these, i've found to get a good jet flame you need the the cans inner wall to be securely glued with JB Weld to the top of the can. keeps air from leaking through the rim. No need to make bottom of core air tight.

Hi, looks very nice. a few things I don't understand:

- the bottom can does not have holes around the outside of the bottom, correct?

- I see in the last picture a small hole in the inner tube going to the outside of the bottom can, is this for the fuel to go through?

- the top and bottom cans are held together with JB weld?

@pjharro You are right on every count except the last. The JB weld holds together the top and inner tube. The top and bottom halves are the same size (diameter) so you get a tight fit when you slip the top half over the bottom half.

@inotnad Great thanks for that. I tried to make one quickly the other night and made it a bit rough and too short, maybe half the height of yours. I also don't have any JB-Weld so the middle was just press-fit in. It fit quite well though. It fired ok but most of the flames came out of the middle hole, the jets were working but were dwarfed by the middle. Do you think it was the shortness of the stove that was to blame?

@pjharro i think the low flame was because there was no seal between the top rim and the inner tube. You loose pressure on the flames to jet out strong, and the gas leaks into the middle hole and ignites.

So let me get this right, top half goes over bottom, correct? Never tells in video and I just cannot figure it out in my head which way I would do it.
