I didn't bother marking out or using scissors or a hole punch as i wanted to try a real "hobo" approach so this is just made from 2 beer cans and i used a SAK "Soldier" to cut everything.
I wanted to make this as simply as possible and i didn't want to use tape to hold it together so i just crimped the edges a little and it held fine.
Fill with meths or in this case Industrial spirits (i use this in my trangia as it burns much cleaner and doesn't soot up the pot's as much).
When it light the flame's only comes from the centre.
After a few seconds the flames start to come out the holes round the side.
I moved into the shed for these pic's as the flames are hard to see in daylight.
It's strong and stable enough to support a crusader cup and one fill was more than enough to bring a half full cup to a roaring boil and it was surprisingly quick.
5 min's turns 2 empty can's into a stove that cost's about as much as it weighs (nothing).
