Re: Building my first oven!! Help me out.
I used 24 ga galvanized on everything but the floor. Some people prefer heavier, but I haven't seen any problems yet. Heavier gauge will take a little longer in the heat-up cycle, but then it won't cool as quickly either.
The biggest problem I think most people make is not looking at their electrical service first. A 96 cu ft oven will take a fair amount of amps to drive the elements. You will probably need a minimum of a 75 amp circuit for this size. If you are looking for a quick heat-up cycle as you stated you may need something closer to 100 amps.
I would think you could build this size for under $1K.
