Log Burner...................

Hi all,

I have had my allotment for 8 month now it came with a big rusty oil drum with a door cut into the side and a bolt welded on to open it the only problem i have is it smokes out the shed wen i start to burn things there. the door isnt completely air tight it has holes drilled in the bottom that i put in to help push the smoke up but it still bellows out from the door any ideas?? problem i have is it has a little ridge jus above the door also.

is there any cheap old stoves out there is so does any one know where

Thanks in advance
