I tried the stove, 1st time I let it run too low on fuel, then added too much at once and choked it, never got a rolling boil but warm enough for a cuppa but it took nearly 20 minutes. Tried again, filled it up with smaller pieces of wood but couldn't get it to fire up, lack of air I think (need a proper grate) Started again with just enough wood to get it going and then kept adding wood, little and often. There was enough heat to keep the lid lifting off the pot but again never a rolling boil.
Still it worked after a fashion, both tests done outside, no breeze temperature around freezing. I'll stick with my Swedish Army Trangia conversion or my MSR Whisperlite Int.
