First of all great site!! I have used a similar home made smoker and am now planning the build of a double walled insulated [1"mineral wool] smoker with a 30" x 30" x 48" inside diameter.. There will be a machie punched heat shield 12" off the bottom [have a machinist friend making the build]. There will be a door to the 36" smoke box and a smaller door to get under the heat shield and the smoke pan. I was thinking of a 220v ~2000w oven heating element and a regular ~1000w range top coil for a smoke pan [independant of each other] The smoker I previously used was a bread warmer with parts from an electric range, oven element and rangetop coil [like i described] Any way.... how does that heating system sound??? I am trying to figure out the controller, relay wiring. Originally I thought of just gutting annother electric oven. After reading the forum I like the Auber PID idea. A SYL-2362 for the main element and a SYL-1512A2 for the smoke element. I know I need relay's for each but have no idea of what I need. Any help would be great!!!!!!!!!!!
