Chimney in back of oven

The oven is beautiful - but am I the only one that finds the stand under it very scary? The blocks aren't straight, aren't staggered, and on the left aren't even abutted to each other. It looks like it is on nothing but dry stacked piers and I'm dubious that they are even reinforced.

You can tell it's not staggered from the first pic of the stand at the top - but the really scary stuff is on the party pics at the bottom. I'm no expert but it looks almost dangerous. There's no way my Dad would have put up with that kind of workmanship.

Really bizarre - such great workmanship on the oven and such cruddy work on the stand supporting it. Even just from a strictly aesthetic POV it's a mess.

The stand is only temporary, as well the oven ,at the end of seminar everything is torn down.

Ah... that's sad but it does explain a few things.

There are old Amish designed ovens that were called "squirrel tail" ovens. The flue was routed back over the top of the dome to the back. It still vented out the front though. I thought it would be interesting simply to go back to the top of the dome but, would make repairs(if ever needed) more difficult.

I guess that oven works much like residential and commercial gas ovens in the sense that they vent the gases out the back with the door in the front. Perhaps an oven shape could be created to allow the gases to more fully heat the oven before exiting the vent. Also interesting that the door could be closed durning firing. As for the flue angles mentioned, how would that relate to the masonry heaters that many masons build in the northern climates? The flue systems of these heaters run horizontally. Cleanouts could be added to the design perhaps? Peter Moore is a heater mason, if that means anything?
