I will build a shop heater in the future, and plan to incorporate a very tall riser with a brick type of bell perhaps. Looking forward to more progress.

For my next CF board core, I will build a square wooden liner. With an outside dimension the same as the inside dimension of the burn tunnel. This wooden form will burn out with the first fire and will make moving and building a ceramic fiber board core much easier.

I used pure fireclay with no sand to stick the boards together. The whole assembly is wobbly as you move it , by having a thin wooden form inside, it would be much more stable while moving.
But more important in my eyes is not having to constantly check dimensions when surrounding with brick.
I had my bricks almost to the top of the core when I realized that I had pushed with each brick moving the top of my side walls closer together. I had 7.5 " at the bottom and 7" at the top... with a wooden form this would be a non issue.
I removed two rows of brick to correct this ... I could have had the whole core covered by now if that little boo boo hadn't happened. Wood form might take 30 minutes to make... burn out with the first fire... no brainer for me.

It is a diamond wheel, I just think of it as masonry blade. It still is on a hand grinder and the safe thing to do, would be to get a wet saw... Luckily I'm almost done cutting, so no need...
