More work on the purlins today. We began notching what will be the bottoms of the purlins where they will sit on the posts.This morning Paul & I built the slab for the oven. It is full of small stainless steel needles that are mixed into the refractory cement to provide strength to the suspended portions of the slab. The randomness of the needles provides fewer places that the slab would be likely to crack along than using rebar or mesh. Next comes a layer of fire bricks which will become our baking surface.
