How thick are walls of your HT oven

[alexmin]

Guys, I am planning to make a HT oven (using soft fire bricks)
Can somebody measure his oven wall thickness and let me know?

Thanks,
Alex

About a year ago I built an oven to do carbon restoration on small cast steel parts. I set the soft brick the 2 1/4" way with a sheet steel cover and after 2 - 3 hr @ 1600 F the sheet steel is at about 600 F. If I build another I will set the bricks the 4 1/2" way but I think a thin sheet of kao-wool would solve the heat transfer problem.
The reason I feel the kao-wool to be the solution the the heat transfer problem is that a foundry that pours a lot of our parts has ovens that are about 4' cubic inside and have walls of 2" thick kao-wool with sheet steel covers and running continuios @ 2000 F the paint on the steel cover looks like new.

that's a case of what you'd call, equalization of the heat
