So I had a brain storm this morning, what if I was to make our outdoor fireplace into a smoker/pizza oven? The fire place was built in 1944'ish and it makes a great fire for us and the kids but it is starting to need some TLC. We love to make our own pizza, but 14" sized pizza stones for the home oven are too small and too slow! I have a smoker, but it is a cheapo from Home Depot. Too much of a pain to use. Here are some pictures of what I have and dimensions: My thoughts: The current total outside depth is 30", firebox depth is 21", 25" tall not including the arch of the firebox and 30" wide. I was thinking of cutting out the back wall, and doing and extension of 12" inside for the firebox. Then raise the "shelf" lip you see in the picture, reline the interior with fire brick and add a shelf front to back on the new lip. Something along the lines of blue store. The blue stone is what I would cook pizzas directly on and smoke meats in pans on. I would also set it up to have metal doors I could remove for pizza, leave for smoking with adjustable vents on them. For the "New fire box my thoughts are for the blue stone, not to extend all the way back. The fire would be below the stone and heat would go up the rear and out the chimney. Does this make sense? The internal extension of the firebox by 12" would allow more food to be cooked at once and the new rear would be angled up to the current chimney. We do use the FP for sitting out at night and s'mores, eventually we will also put a patio around the FP. I have access to a concrete saw and a source for everything else, does this sound like a great idea or just nuts? Any suggestions?
