Kiwi pete's oven
Continued from my previous postings Brick Oven photos forum. if you want to see those, go to http://www.fornobravo.com/forum/f21/...-oven-302.html
Originally, I was going to incorporate an archway into the opening of the oven, similar to what paulages has done. I did a mockup of it as you can see in the picture.
I could sorta figure that out, but how to do the vent was giving me a hell of a headache, so I decided to change tack:
Decided to do a refractory manifold and vent, similar to what Forno Bravo sells with the Casa oven: http://i29.photobucket.com/albums/c2...entGraphic.gif
I first made up a template out of a bit of cardboard to make sure my measurements were OK.
Went inside for a while, and when I came back, found this:
Typical bl**dy cat!!!
Then I made up a mold to cast the refractory concrete in, with a bit of reinforcing iron for additional strength:
Here is the manifold in place, from a few different angles.
Also managed to a few more courses of bricks in place!!
Next I'll be looking to cast the actual vent part.
nice work! by the way, the vent was the easy part with the arch. it was making the cuts to tie it into the dome that was hard.
I agree with Paul. The initial arch tie-in to the dome was more difficult than the actual vent by far. I went with the arch approach with no regrets, but I love what you've done with yours. Beautiful oven! :)
Time for another update (and pics) of my oven.
The cat has taken a particular liking of the oven. The other day I had it covered (in case of rain) and when I came outside, I found this:
Have started doing some more courses of bricks:
I'm now getting near the end, and for a better fit, have started cutting my bricks in half and also cut them in a (sorta) trapezoid shape. (some of them more trapezoid than others, depending on what made for the best fit.)
here are some pictures of that row:
I will probably finish off the dome in the next 3-5 days, and am getting quite anxious about removing the vanes, once it is dry.
I'm quite worried about the whole thing collapsing. If that happens, I'm going to be bl**dy pi**ssed off.
I'm probably worried about nothing, but here is a question: who has this happened to (on this forum) and what did it take to fix it??
KiwiPete's dome will not cave in!
(M) Unless you forgot to put cement in your refractory mortar, I'd bet a Kiwi that your dome will hold. It is very carefully fitted. Congratulations! :cool:
(M) If I were to build another Pompeii I would use your manifold idea though I'd probably use two "circles" of re-bar. Your casting is a definite improvement on my use of plain flat iron to support the chimney. It requires no mortar joints to fill :) .
(M) If you post again please specify the diameter of your oven. If I gauge by assuming the size of your NZ bricks are close to ours I would guess no more than a 36" ??
(M) Your arch bricks are already cut so if you house your igloo, you could use those same bricks for a decorative arch that lies next to your cement board, or "HardiPlank" siding.
