36" vs. 38"

Re: 36" vs. 38"

do I need to cut the bricks on the floor? can the first course of wall bricks set on top of the floor bricks. and have some of the floor bricks sticking out from the walls? I could break the longer ends off that are sticking out. this would save making round cuts on floor fire bricks.

Or is it more thermally efficient to cut the floor bricks and have the floor inside the walls?

You can just let them hang out without cutting them if you're going to put your soldier course on top of the floor. That's what I did. When you get around to insulating the outside of the dome, you want the insulation to go all the way down to the bottom of the ragged floor brick edges.

I actually made up the templates so I could work out a pattern where I don't have to cut the floor bricks, or at least minimal cutting. My plan is to have them hanging out a bit and then just cover the corners with insulation.
