I have read somewhere on internet, that laying Brick in bottom of chamber will work.
Has anybody else used this technique or have heard of it?
seems like it would work to keep the temp stable and to get faster temp recovery after opening the chamber, much like a pizza stone works in your oven. I would think you would want to place it as close as possible to the fire box...
Bricks will not insulate much but as stated above helps speed recovery. If it is 20° and windy even the bricks will make little difference. Many guys wrap the chamber with a Welding Blanket...JJ
I picked up a 6'x8' welding blanket from Harbor Freight for $20 and it works fine. In the winter I used it on my Weber gasser before I got my Yoder. I now use it on the Yoder as well especially when it's windy.
