After several requests, i have some pics of my fridge conversion and smoke generator. the fridge is a 1958 model GE that had the little freezer compartment in the top. the interior is porcelain over metal and it has 3 inches(!) of cardboard insulation. we had to take 8 plastic panels off of the interior and the door and replace them with 20 gauge sheetmetal sealed with silicone sealant. i used my new silicone sponge door seal and it looks like its going to work pretty well. the interior is 24x14x42 tall and i should be able to smoke 6 small turkeys or 12 pork butts at once. should be fun. my smoke generator is made out of a 3"x18" piece of schedule 40 pipe with end caps supported on 3 rebar legs. the upper pipe is 1/2 inch black iron and there is a 1/4 inch threaded pipe in the bottom cap. the smoke will go through a 3 foot piece of high temperature silicone hose seen in the picture. i am going to install a hose barb on the back of my gas grill as well so i can smoke/bbq using the same smoke generator. i should be able to get 6-10 hours of smoke out of it. this smoker will have an external 1250 watt heat source with forced air circulation. it will operate as a large convection oven with forced venting and added smoke. next week my fan motor arrives and i will start plumbing in the wiring and heating ductwork on the back.
