Go to your local fabrication shop if you have one or metal shop and find some 1/2" rod and some 1/2" inside diameter heavy wall pipe, SEAMLESS, and make some simple, yet strong barrel hinges. Very simple to make and will out last you and your smoker. Depending on how many hinges you think you need, make them about 4 inches long. Cut the rod into 4 inch pieces and the pipe into 2 inch pieces. Insert one of the 4" rods into the one of the 2" pipes, flush one end and weld together on the flush end. Then slip the other piece of 2" pipe over the rod on the pieces you just welded and lay that on the seam of where the smoker door is and the smoker itself. Weld the piece of pipe that you just slipped on, to the smoker body and the other end to the smoker door. Do the same thing for the other end of the smoker only reverse the way you have the hinges so the smoker door does not fall off or slide out of the barrels. Make sense? If not, let me know and I will send you photos of how I did mine.
