I'm happy with the use of this thing, but I need more experience. A big problem I'm having is dome temps. They're all over the place. It may not be a problem, it just has to do with whether there is a live fire or if the fuel is smoldering.
The objective I set out to acheive at the beginning of this project was evenness of cooking, crucial for a pizza. With this rig, the only thing that will burn the bottom of a pizza is placing the fuel beneath the stone and not on the perimeter. I've observed this several times.
What keeps tugging at me is using wood for fuel. After briquettes are started, this thing is pretty damn hot and new fuel catches fast - and burns fast. Also, since so much of the perimeter is accessible with the hinged grate, removing the dome, charging fuel and regaining temps isn't such a big deal. I do it routinely. Now, I want to try to recharge with two logs on either side. Once they catch, I'm curious about the temperature and the burn time. So, that experiment's on tap. I also have a few friends queued up who need some samples for tolerating my babbling about this thing.
