I’m in the process of building an 8x8x7 oven in my shop and am getting ready to outfit it with the elements. I have been considering all the options, gutting ovens for the controls, purchasing standard oven elements, etc… but I was wondering if anyone has ever used the finned oven elements like the ones I attached. They are rated to 1200F and are 5000W units. I would think two of these would be enough but I am not sure. What do you guys think?
