Hi Chickade,

From looking at your floor and hearth, you're using Scott's mass concept. What are you using for hearth insulation, other than fire bricks? Look like too much mass for me?

I like the idea of steel trusses, as it seems simple, though I would have to find someone to do the welding.

Can you comment on what someone who has limited masonry skills could do about the back of the oven and it's arch? I understand that using the Alan Scott method would make the oven prone to cracking at that joint between the oven back wall and and arch.

There would be no welding needed. 2 pieces of c channel, some all thread rod, a couple nuts and washers and you are set. Biggest pain will be drilling the holes in the steel for the rods.

To avoid the expanding arch tending to push the back wall out, the top of it should sit under the arch. Kilns built with this configuration should be done that way, although they are subject to greater expansion. the longer the arch is the greater the expansion and therefore the more of a problem it is.

Yeah, the oven Tom is talking about is a Montreal style bagel oven. It's kinda unique, it has secondary air inlets, multiple flue paths, a raised hearth where the fire sits, and the offset door.
