I built a smoker last year and decided to put a PID controller on it. One thing led to another and I decided to build a brand new one. I found an old GE fridge that seems perfect. Here's a few pics of the progress so far. Here's the old one. It's obviously a lot more seasoned now. My cold smoke generator. The new smoker to be.I got a 3000 watt element for the heat. I'm going to drop the bottom 6" so the element will be lower.
