I have posted this in "other builds" and nobody had made the first comment after 120 views. I am hoping some of you electric smoker guys can help me out. I have acquired a large stainless box (industrial electric panel box) that I want to turn into a smoker. I also bought a stove that I plan on gutting and putting the heating elements and controls on my box. Questions I have: What insulation works best for this? Will a residential oven provide enough heat for this box (3'x2'x6')? I want to be able to put a probe in the meat and have the heat automatically shut off when it's temp reaches xxx°F, how do I do that?
