With the hearth in place, time for the dome. Six pieces create the oven dome and lock the floor down. The pieces are keyed and (thank god) numbered. Piece #1 was the mouth of the oven. Quick tip: concrete is much heavier than it looks. I pride myself with the ability to pickup almost anything (including car tires, logs, crying babies…excluding sorority girls, trampolines, restaurant checks, the list goes on). But, I could channel Lou Forigno all day long and still not be able to pick up the monster that is Piece #1.
