I took 2 55g drums and cut one length wise and laid the other in it and welded the sides. The top drum I put a pipe from it into the lower to feed the fire and the top is a sealed drum with the hole lid that removes. fill the top drum and start a fire in it for about 15-20 minutes, and start one in the bottom. after the time runs put the lid on the top and feed the fire for about 8-12 hrs. lot of beer......let cool for a day and open.
