I don't think the dome height is going to work, it's too low to be able to build a good hot fire.

The dome height won't be an issue, but many other things may.  My oven has a 13" dome and I know others have lower.

Yes, but isn't your oven wider? I should have said the height to width ratio is poor in this design.

I might suggest you go to the Forno Bravo Forum And look at Alternative Ovens. Lots of things there you can do.

My oven is small, 30" diameter.  There is a guy over at fornobravo with a 21" oven.  Small ovens lead to smaller fires, but there is also less to heat.  So long as there is room for wood and a opening big enough for sufficient airflow and oven should generate flames.  Problem A1 here looks to be the vent.  I can't really make it out in the picture but it look to be at the back right above the fire.  This is all wrong.  It looks like you twisted the barrel to get the vent height lower then the peak of the dome, but it still needs to be at the front.  If you can get the vent worked out so the heat flow is correct I'd then parge the dome on the outside with homebrew mortar and cover that it lathe so when the mortar cracks it will stay fairly in place.  That would be a cheap easy way to add mass that seems fitting with the building techniques used on the rest of the oven.  Your probably never going to get this oven to hold 1000F hearth temperatures for hours on end like a traditionally build oven, but I'd bet with some tinkering you can get it to 700 or 800 for long enough to cook at least a few pies.

i have since redone the chimney
the chimney opening is at the front, and now it is significantly larger (how will that play in airflow?)


so you are saying that the oven NEEDS more thermal mass on the dome? and that will help it cook better? ok
and i appreciate the mortar idea, but what about stacking a layer of bricks on the top of the dome, right above the apex of the fire? - how will that be different?

what are some things that i can do to get my oven to maximum temperatures (hopefully 900)

i dont need to retain the heat very long, as i only do pizza
