Hi all,
I'd first like to express my admiration at the creativity and engineering capability of the folks on this forum. You have truly inspired me to think that I might be able to build an oven myself, despite my lack of masonry skills. So thanks for that! -- (wife not so thankful, however, since all I've been able to talk about for the last two months is pizza ovens!)
I'm in the design stage for a 42" Pompeii.
I'd like to build the dome around the floor to maximize heat retention. I've noticed that a lot of the ovens on the forum that use this design DO put in a gap between the floor and the dome and between vent transition and the entry arch to allow for thermal expansion.
However, once into the vent landing, it looks like most people do not leave a gap for expansion between the vent landing and the vent structure/decorative arch, and between the firebricks and the oven landing.
I'd appreciate thoughts on whether a gap between all floor bricks and all vertical structures would be worthwhile. In my newbie way of thinking, there's a lot of heat in one of those ovens and the more expansion joints the better. Even if the vent landing floor isn't getting too hot, is it moving around as a result of the expansion of the cooking surface bricks?
Any chance the lack of such expansion joints might be causing some of the issues with cracks in the arch and other structures?
Thanks,
Jim
