My build was sadly put on hold while we have been playing catch up at the machine shop after the snow last week. Alas, I should be gathering the remainder of my materials/supplies this Friday and progress will ensue. In my search for various products and parts, I stumbled upon a decently priced 13" diameter, 1/2" thick ceramic pizza stone. Would thissize stone restrict the heat/smoke flow? I know most builds comprise of a 12" terra cotta or something similar but I just thought this may have been an option. Thanks fellas
