CyberDawg, i dont consider a cracked fire box to be broken, this is my 7 piece firebox. ive been cooking pizzas up near 750, starting to look at making dough as the store bought stuff seems inconsistant to me, one comes out great then the next day same setup it gets a burnt bottom, same dough. i like how much airier the quickly cooked pizzas come out with just a bit of crunch
