  • CUACNOPALAN, Puebla, Mexico

    I am advancing with my build and have got to the point where I have to decide on the entrance/exit arches, chimney and landing.

    There are just so many dimensional designs "out there".

    My confusion rests in the design and dimension of the "entrance tunnel".

    For example, these are some of the many possibilities:
    • Oven with no flue and chimney
    • Oven with flue and chimney directly outside of the oven
    • Oven with flue and chimney and a STRAIGHT SHORT "tunnel". (9 ")
    • Oven with with flue and chimney and a STRAIGHT LONG "tunnel". (14")
    • Oven with with flue and chimney and a EXPANDING LONG "tunnel". (14")
    Any ideas on what the varias pros and cons are ??

    A lot of those decisions depend on how you plan to build it, materials, cost, labour, skill level etc. Brick or cast, with or without flue gallery (maybe sheet metal)
    Kindled with zeal and fired with passion.

      It seems to me, that a longer "tunnel" will promote heat retention at the mouth of the oven but:
      • The longer the "tunnel" the less accessibility and less visibility.
      • Having a longer tunnel that opens up (expanding) might be a compromise ???

        Thanks David.

        My design is taken directly from FORNO BRAVO, 36".

        Standard fire-brick and a chimney that I will build from redbrick.

          Dr. L,

          You should probably start a construction thread now that you are under construction - Pompeii Oven Construction

              I've been thinking about this too. I ended upp making a full scale model of the oven with a small trampoline and wooden play bricks and fooled arond with a peel and plastic lids as pizza dummies. I prefered the shorter tunnel for accessibility. For the moment, it looks like about 33 cm is feasable for me (36").

                Thanks Petter,

                I also came to the same conclusion.
