The Firedome project is my pride and joy. Although I can rely on it for pushing out a nice pie for friends, I still play around with ideas for changes. Here's a newer version that didn't quite work as I wanted, but the final cut shown in the last image reveals what may be a slightly better design than the current one.
A sample pizza (ok four) were run through for a test (and light lunch). They were uniformly cooked, but the opening made it a pain to get them in and out and feeding wood was also tougher.
