built and tested hobo stove

[BeardyMan]

I've seen it done with tins similar to paint tins (bit thicker walls though, and never had paint in 'em!) I suppose something with thinner walls could be okay as long as you're not relying on it to hold the pots / pans up. Wouldn't want one of the walls giving way with all the weight of your cooking and heat from the fire. Could end up with some nasty burns should it fall over. Highly unlikely I know, but, well, ya never know.
