I got a lovely firebrick arch but I am struggling to decide at which stage to put it in place. I've seen some people doing before the first clay layer by creating a sand form between the dome and the arch; others put it after cutting the door on the first layer.
another query! (sorry guys) I got a stainless steel chimney but I wonder if it is a big too big and heavy for my oven of 760mm internal diameter. The chimney diameter is 150mm. I will put it between the brick arch and the internal layer of the oven. Any thoughts appreciated.

The pipe diameter is correct for your sized oven Regarding weight the pipes are usually made from 0.55 mm 304 stainless. There’s no reason it couldn’t be thicker apart from the fact that a thicker pipe will have much more power when expanding. You should, even with the lighter weight pipe, make allowance for its expansion or expect cracking around it.
