    Re: Karangi Dude's 48inch Oven

    Getting ready to start the curing process.
    I made the handles for the door and then made a Heat Bead Chimney to start the heat beads (it should only take 10mins or so to get them started) I can then tip them straight into the oven and spread them evenly over the floor out to 4" from the walls. I will not be having any flames in the oven during curing. I plan on using several bags of Heat Beads over 8 to 10 hours adding about half a bag per hour pending on temp readings of the Thermo Couplings that I inserted in the oven. I hope to heat the oven as evenly as possible and then retain the heat as long as I can by placing the door on after the heat beads die down.

    I had a flue fabricated by a friend who specialises in wood stoves and heaters he dropped it off this afternoon so it was there when I arrived home from work. I took advantage of the fine weather and fitted it tonight, it went up a treat. I lit a small fire to see if the oven would draw and sure enough it was just fine. It does not matter how much research you do, your never quite sure if things will work the way you planned, in this case it was all OK yeh!!!!!

    Enclosure is taking shape I have made the front arch to look like a "Cloche" a cloche is a dome cover for food. The height of the enclosure will be as is, with a temporary roof covering the dome, until I knock down the car port and build the cover over the entertaining area.

    Thanks Lee,
    The idea for the back cutting of the door arch bricks I first saw at Field Furnace Refractory's Web Page there is no real plans or formula I just used their idea.
    Lee I watched one of those Home Reno shows on TV a few years back and they put an oven in some guys back yard and I thought that's for me. I read a book by Russell Jeavons called Your Brick Oven that got me really thinking. So I started researching, I watched Pizza Bob's first part of his build on Youtube and at the end he thanked the Forno Bravo Furum so that's how I found this site. I also looked at the Alan Scott and Rado designs before deciding on an Igloo style Oven. I was not really influenced by any one build I just used ideas that I got from all of my research and a few of my own. My oven is not about looks it is all about peformance. The final appearance of my Oven and Outdoor Kitchen will not take place for a while as the construcion of a new 2 car garage and work shop needs to happen first to free up the area needed to biuld the Kitchen and Entertaining Area that will include a Bar, Argentine Parrilla, BBQ (Grill) and seating for about 20 to 30 people. I plan to be cooking for a lot of guests even one day openning a B&B or small Restaurant (may be!) we grow all our vegetables so there is lots of fresh produce available.
    Regards Doug

    Dude (Doug)

    You have led the way with innovations during your build!

    I noticed several leading edge tweaks to the plans I wish I had incorporated in my build (a few weeks behind you). The biggest innovation I saw you do was the angle cut at the back side of the inner arch.



    Using this cut would have saved me a lot of cutting.

    I've included you in my recommended readings thread. I'm curious, which fornobravo oven builds influenced your design and construction?

    Insulation all complete, I laid some Insulating fire bricks to create a barrier between the oven and the outer chimney to stop heat transfer for when I build the outer chimney.
    I used 2 rolls of ceramic fibre insulation blanket 1" thick, there was enough to cover the oven and the entrance almost 3 times. I will also be filling the enclosure with loose vermiculite.

    Getting ready to insulate the dome, started building the enclosure while waiting on the probe that will give me air temps of the inside of the dome, I placed it just next to the door arch that way it will be out of the way of the cooking area and the fire. I made a mock up of the door to see if it would fit seeing the outer arch is the same size as the door arch. To help stop smoke coming out the front I built the outer arch and the door arch 20mm smaller than the flue arch.

    Hey Johnny,
    If she fails year 10 I might think about it.
    Just kidding she is doing very well she wants to be a Music Journalist.

    Hey Paul,
    It would be pretty hard to take a pic of me on top of the oven at this stage as it is nearly up to our carport roof perhaps I could simply lay on it for you but that would not have the same impact.

    Cheers Guys and thanks

    Great photos Doug. We also want to see one of you standing on top of the dome to prove that you have faith in your brick laying!

    Stunning what more can I say. I especially love that piece of granite/marble you have in the entrance. I might try something similar if I can source a piece at a reasonable price.
    It really gives the oven a smart finish.

    Finaly got to clean up the floor.
    I forgot how it looked, I finished the last bit of pointing on the inside of the enclosure. So now I am ready for the insulation and brick up the enclosure.
    My 15 year old Daughter decided she would like to see if she could fit in my oven she is 5'4" so lucky I built a big oven.

    Hey Chris,
    Thanks I think I could do with a trip to the States.
    Chris I am planning on curing the oven when it is completely finished eg. insulation, flue and enclosure etc. I am using 2 layers of thermal blanket then I will be bricking up the enclosure and filling with loose vermiculite. I plan on curing the oven with heat beads that I will fire up outside of the oven and then spread them all over the floor out to about 4" from the walls. I will continue to add heat beads for about 8 to 10 hours. My theory is to add heat to the oven as evenly as possible that's is why I want the insulation on so that the heat is spread evenly over the whole of the dome. I am not having a FLAME at ALL just lots of radiant heat, I plan on also keeping the heat in the oven for days by placing the insulated door that I am fabricating out of Insulation board sandwiched in steel. I will be monitoring the temps with Six thermocouples that I have in the oven that will be connected to a Multi Channel Indicator.
    Anyway that's my plan, sorry for the rant and thanks for your kind words.

    Regards Doug

    Hey John,

    Thanks for your kind words, but I think you are far to generous.
    John I just like to do things right, but my Wife always says everthing I do has to be bloody perfect, I think she exaggerates a little. I am into symmetry I think that's what probably annoys my Wife the most.

    Regards Doug
