I decided to make a smoker when I got a stainless tank that just looked like I could make something with. The smoking chamber is 18 in in diameter, and the charcoal box 16 in in diameter. I coule really use some input as far as what needs to be different or what i am missing etc. Then I need to get to reading up on the smoking process, so I can get started. I am still building but here is the progress. The Smoking chamber started as a burner housing on a Landa pressure washer, similar to this: The charcoal box started as a water treatment tank made by coffin wate systems, similar to this: Here is my progress: I am going to have a 3.5 in stainless smoke stack coming out of the top center of the tank, the grated portion of the smoker door is going to be covered by a peice of stainless welded to the door. There are a couple other holes that will be welded closed on the smoker chamber also. The top tank is being welded with stainless wire, and will be left unfinished. The bottom will be painted with high temp black. The flange on the bottom is a steel tube that goes through to the bottom of the tank, I figuered it could be used as an air intake, there is also a 3/4 pipe threaded hole directly in the bottom center of the lower tank. I am thinking of using the charcoal grates for a 22" webber as my grates in the smoke chamber, probably 2 of them, also a rod going accross the top for a hanging option. A couple questions: The hole in the bottom of the stainless tank is about 4 in. does that need to be bigger or will that be fine? also should I make that opening adjustable with a baffle of some sort? Should I baffle the exhaust stack? Is there some type of high temp seal tape or something I can use on the smoker door seams to get a smoke tight seal? Any ideas for a latch on the smoker door? Well enjoy and please feel free to chime in, I welcome and appreciate criticism. Will update with more pics as build continues.
