i made another smoker last night at work. i took two 55-gallon drums, and put them open end to open end, using a lid collar to hold them together. i used the plasma cutter and cut two access doors, and a smaller door at the bottom for charcoal/wood. our mechanic made up a food rack and welded some angle iron, just under the top door, inside for a rack to rest on. he also made a small rack for charcoal/wood to lay in the bottom. i found a 3" 90*Â° elbow that we used for the smokestack, welding it in the side at the top. he made some latches to hold the doors shut, and welded up some hinges on the doors we found laying around in the plant. one of the other guys plans on learning how to smoke meat, and it was for him. the bad thing is, he doesn't have a computer, now does he know anything about the internet. (he is 67 years old, and never had to do anything on a computer before.) i also got some insulation i am going to wrap my smoker in, in an effort to trap the heat inside better. it is a thick white colored fireproof insulation, with foil on one side. i plan on wrapping it today, and posting pics of it this evening. i didn't get a pic of the vertical smoker the mechanic and i built.
