Before staring on the steel work, I decided to mock up the soldier bricks that will support the roof dome. I also rendered the cast lintel with refractory mortar to give the surface a harder wearing outer layer and to fill any voids. This was a great suggestion made by Terry on The UKWoodFiredOvenForum. If anyone is planning on building their own oven, would recommend signing up to this forum and discuss you plans with the other members.

For my steel arch strapping, I have chosen to use this 'C' section, I was not entirely sure what size to use, without going into engineering calculations, so instead I used the largest size I could get. My oven design has a low, parabolic arch which will produce a substantial outward force on the soldier bricks, so it is very important that my strapping is ridged enough.
