Saw the neat thread on here about them and decided to make one. I used the instructions from here:

http://www.bushcraftusa.com/forum/showthread.php?t=6270

I had some aluminum cooking grate that you use on your gas BBQ, for people too lazy to clean their BBQ I guess, for the grate in the bottom and the pot holder. Not sure if it is going to hold up but I will try it. I have a couple of other ideas for the pot holder that I will try out too. The current one can be stuck inside the bottom of the can and lid of the can goes back on for transport. Once you push the progresso can into the paint can it seems pretty permanent, I had to hammer mine a little to get it to go. But just to make it bullet proof I will drill a couple holes about halfway up (so to not interfere with the potholder storage) and put a couple stainless machine screws thru both cans to be sure there is no way for them to come undone. Might be unnecessary but it's not like it'll cost anything.

I also bought some flat black high temp spray paint to paint the outside with so hopefully it stays a little cleaner or is easier to clean.

Cost? Well it was two bucks for the empty quart paint can. I had to buy a can of progresso soup, not sure if it counts as a cost since I got to eat the soup. I had the grating on hand and it was like $5 for the paint. Took like 5 mins to make. If it can boil water and fry an egg using scraps of wood I can find for free I don't see how I could need anything more.

Tommorow I will fire it up and try to boil some water and fry an egg and report how it works out.

Could you explain how it works some?

I assume it does something besides just burn the twigs at the top of the can?

Thanks.
 
Check out that link I posted with the directions its got the scientific stuff in there. Something to do with the airflow between the cans makes it a hotter fire with less fuel than a regular hobo type stove.
 
OK tried it today. The aluminum BBQ screen I used for a pot holder melted so I gotta go back to the drawing board and figure out something for a pot holder. Was easy to light and made a nice hot little fire. Be back with pics when I get a new pot holder.
 
Use the harware cloth in 1/2" it works out well and you can store it in the bottom between the cans. Make sure you post pics.
 
your post, plus that thread from the other forum inspired me to scrounge around, granted, mine came out a lot smaller as i could only find smaller cans, and the holes were not the best, but it did burn pretty hot without any smoke, and you could see the little blue gas flame coming out of the top holes of the inner can, so semi-success !! will go to the hardware store tomorrow and get better sized cans.
 
They wamted $9 a roll for it at Lowes thats why I tried to skimp :(

Gonna have to go back.

whats the harwire made of?
i have some wire i got at the hardware store, seems almost like galvanized or something. would that work? or melt as the aluminum did? picked up the cans yesteray. the only one my hardware store had was coated inside but figure i can burn that out yes? then go from there. thanks for the idea. looking forward to getting it made today and trying out with the wire i have. if its successful will try on a hike sunday.

That is the stuff. It is just 1/2" galvinized mesh. I have also used the lined cans, it burns off.

cool! thanks!:thumbup:


so how many burns can ya expect to get outta this setup?

I wouldn't even venture a guess. the first thing that is going to burn out is the mesh grate in the bottom of the inner can. That's about 50 cents worth of hardware cloth and 5 minutes of your time. I have about 50 burns on mine and it is going strong.

Have fun playin with fire.
