I understand you are creating a new dome to replace the shield and top stone. How much space will there be between the rotating table and the dome? Less or more than what is there now? I was worried that there would not be enough air to FEED the flame with everything "buttoned up" so to speak, but then remembered photos of brick WFOs that have the gas option. I started to think your idea would work, but then realized the outlet for the burner on those ovens is positioned on the floor of the oven with the whole inside of the oven providing the air to feed the flame. Your flame will be under the turntable with only the opening for air being the open space on the floor surrounding the burner and and what is available between the table and the dome. Would you have a fixed height for your table then, or would your dome be positioned at a point where the table could be adjusted slightly up or down. I'm just worried that your burner will be located in a little "cave" under the table without enough open space to allow air to be drawn in to feed the flame. Don't get me wrong, I think this is a cool project and want it to work for I see it as a future "All Season Blackstone" next winter here in Chicago. Take care!
