I'm totally new to this forum as well as the idea of building an oven. I hope people can give me some advice. I'm building the oven for just my wife and I. We'll bake bread twice a month and an occassional pizza, maybe a roast, or corn on the cob, etc. I'm building it mainly as a failsafe against a long term power outage so want to build it on the cheap.

I happened to find a great deal (I think) on high quality firebricks. They were destined to go inside some ovens at a steel mill but they changed their minds. Here are the bricks I got. The small ones were 35 cents apiece, the large ones were 50 cents apiece and the arched one is a dollar. The small piece has 60% alumina, the others 45%. Is this too high?

I thought I'd make a 3 foot by 3 foot oven (interior dimensions). I'll use the larger bricks for the hearth. The arched pieces give me a 10.5 inch high by 15.5 inch wide doorway. 10.5 is exactly 63% of the interior dome height.

I don't own a tile saw so will be borrowing a neighbors. Since I don't want to do a bunch of cuts, I came up with a domical vault design that (I think) will combine the advantages of a dome with the simple construction of a vault. At least this is the idea. Since the vault brick pieces are tapered, I can get by with a very thin joint except where I want it to curve more to give me a slightly lower ceiling. Also, I'm not sure if 3 inches of brick is enough for hearth and dome. I guess I could add an inch or so of refractory conc if needed.

I'll frame the opening with a stack of the smaller bricks that match the height of the arched piece. I'll fabricate a vent over that.

I'd really appreciate some feeback since I'd like to start on this right away. Thanks for a really good forum.
