Thanks for the replies. I've been reading up in other threads here on other guy's smoker builds. My cob oven is wood fired, which translates to constant PITA temp control.
Most likely go with the electric two burner hot plate initially, as we are going to put in a huge amount of solar and a couple VAWT Wind turbines. Might end up converting to propane later though...use propane in my mini forge with a Reil burner.
I would appreciate any thoughts on shape and vent placement, as well as heneral structural ideas.
This is the design I built the oven from. Anysuggestions on mods to make a smoker welcome and appreciated.
