More progress on the oven, though it still isn't finished. I bought some high temperature caulk (good to 750 deg C.) and sealed all the joints between the steel and frame on the inside of the oven. The caulk hardens like clay.
I was able to get the oven to 700 deg F, which is about what we need. However, when the oven had cooled down a good deal of the caulk had separated from the metal and fallen onto the floor of the oven. This is because of warping of the steel that occurs when it reaches a high temperature. I have the steel attached to the frame with bolts spaced 12-18 inches apart. By putting additional bolts along each edge of the steel I think I can contain the warping and that the caulk will stay in place.
