I'm the guy from another thread who built a brickwood oven and am trying to modify it. One of the suggestions was that I close off the chimney, add an entrance arch at 63% and put the chimney outside of the entrance arch.
I've built the arch and closed off the front of the oven, but I'm wondering about how to go about closing the chimney. Can I just put firebricks over the opening and have a a five inch square hole in the top-front of my oven that is four inches deep. That would be the easiest thing.
Alternatively, could I screw some kind of metal support to the ceiling of the oven and put bricks on top of that?
I tried mortaring in bricks but it doesn't look like they were going to hold so I knocked them out and now I have a five inch hole in the top of my oven.
I know these are totally newbie questions. Any help is really appreciated.
