Found an old rusty drum at moose camp with the top cut out & several holes. It was raining so I built a fire in it on it's side, worked ok but smoke rolled out the front right at us. Moved it so the wind blew into the front was better but when no wind smoke in the face again. Tried knocking a hole in the back-top-side so the smoke would go out the back , no help. Finally I put the barrel over the fire, smoke came out the big hole I 'd made ,now near the top, it got hot & less smoke. Better heat & no sparks. With a drum with no bullet holes, I think I'd have a better stove but it worked pretty well. Down side, is to add wood, I had split the wood small enough to go thru the hole i cut to let smoke out & to regulate air in, I place a rock under the bottom, I cooked & boiled water on the top. I've no idea where I'm going with this but other wood burners may relate to the playing with fire. A good thing to remember if you are ever stranded & have a 55 gallon drum laying around.
