I see it is 19 days since I posted my last thread and I have been unable to make progress on the oven because of damp weather. The delay has given me time to dream up some more questions as I visualize what the oven will look like at each stage.
The Forno Bravo plans call for a 10" chimney for the 42" oven. My woodstove in the basement has a 6" stove with two 90 degree bends in it and it draws well. Is it really necessary to have a 10" chimney? Would a 6" suffice? Or an 8"?
I am going with the herringbone layout for my hearth bricks, but I am considering cutting them at the opening to the oven and there laying down 1/2" vermicrete mortar to act as an insulating barrier before finishing the brick work out onto the landing in a regular pattern. Obviously the purpose of this extra work is an attempt to prevent heat loss from the hearth bricks out onto the landing part of the construction. The regular pattern bricks on the landing will be mortared in place then covered with a tile to give them a decorative finish. I anticipate having to cut down the thickness of the bricks in order to accommodate the tile and leave the surface flush with the hearth bricks. Does anyone have a comment on this idea?
