    Thanks Karangi Dude Doug. The chamfers are to assist smoke flow from the oven to the chimney vent past what would otherwise be a dead corner I assume. I will dry stack and pre-cut these before assembly.

    Hi Don,
    Here is pic of a basic layout for a good size barrel oven, the door width is 50% the width of the barrel and and works out easy to do. The width and depth of the oven is about 920mm x 920mm without the entrance area
    Cheers Doug

    Thanks IL PIZZAILO
    I'll modify my build to that principle. The oven I am copying had walls built beside the vault. I can see how it may have moved over the years but i dont know if it did as my friend sold his house and moved away.

    The front and back walls of a barrel oven or kiln should be built under the vault rather than beside the vault. The expanding vault has a tendency to push the walls out. The usual method of holding these ovens together is steel bracing.

    The design im using has the flue next to main chamber. Will this prevent from baking after pizzas if I cap the flue to avoid heat loss.

    I suggest you look at Karangi Dude's thread, he recently did a new hybrid barrel design and from Aussie land. Also I believe Tscar did a nice barrel as well.

    Thanks Steady. Building at a shack in central highlands so want to get it right as external temperatures will be high and low over the life of oven.

  • Should the first two rows be mortared in barrel vault design?

    First time builder of barrell vault design based on Forno bravo. Have read posts reccomending the first two rows of fire bricks in main chamber be dry stacked. What is the reason for this? A commercial retailer told me to mortar everything. Confused Digga Don Tassie
