I started a second smoker just smaller than the first I built. This one may end up with a friend or I will use it for small loads. A single 1000W hot plate should take care of heating and smoking duties. Haven't done any temp testing yet, so I may need a second just for good measure. Inside dimensions H36" x W12" x L26", nothing huge by any means. Same build as the first, 2x4 framing, 1/4 plywood sheeting inside covered with aluminum. Outside will likely be tongue and groove pine. Same Temp control as my first, one thermocouple for chamber temp and one for meat probe. Here is the progress so far, about 4 hours total.
