Semi-permanent Shell for Fire Pit to Make an Oven Answered
I'm looking for a semi-permanent solution to making a fire pit into a wood fire oven. The shell could be something modified from an existing item or something from scratch.
I'm thinking a dome shape similar to a brick wood fire pizza oven would be best, however I would want to be able to remove it so the bottom portion is functional as a fire pit and could also be used as an open pit/grill. It would probably be more on than off, so semi-permanent is okay. The pit itself would only be about 2 1/2 to 3 feet in diameter, so nothing too big.
As far as functions, I would have a grill at the top of the fire pit (maybe height adjustable within the fire pit, but that's getting kinda fancy). Then in "oven mode," I would have the grill in and put a ceramic pizza stone on top of it for baking then the cover on top. And perhaps even without the stone as a smoker/meat slow cooker.
Ideally the cover would be well insulated to keep the heat in and well distributed. It would also have a cutout or door for putting in bread or pizza (rather than a cover that lifts off losing a lot of heat in the process). I'm not sure what materials would be good, but it should probably weigh no more than 75-80 lbs. (light enough for one strong person or two middling strength people to lift). Maybe an inner dome of some metal with a layer of some kind of flame resistant insulation and then another outer dome of more metal? It would also have to be weather resistant for cold winters. Some assembly might also be good as the individual parts would be lighter, so long as being in pieces doesn't compromise the overall effectiveness of the "oven".
I've tried searching for a few things, but nothing has really popped up that fit this description.
Any ideas would be greatly appreciated. Thanks!!
