progress on the oven fall / winter 2009

what we started with, 2009

[windage]

since 'photo bucket' became 'photo pirate' and hijacked our pics..these are from the last few months..

[windage]

seems like a little over a thousand..with very few storebought modern bricks used, most all came from salvage in the next town over that had a firebrick factory

[Alomran]

Out of curiosity, how many bricks did you use in the end?

that is a screw jack leveler from a builder's scaffold, so that I could simply lower it down when done for removal...worked great!

Finally able to get back to work on the oven...finished up the perlcrete girdle, trimmed the centers (support frames) and began setting them..pics to follow.

I cracked my inner arch and decided to totally redo with different mortar anyway.

What did you use to make the metal stand that hold the circular wooden ring upon which thtimber arches sit? Is it from a swivling chair?

[windage]

most of the concept and ratios came from the book; 'The Bread Builders' by Daniel Wing and Alan Scott..the technical help came from my good friend, now Congressman, Thomas Massie

found that in the very first paragraph of this thread..."6ft 9 inch inside and 24" tall dome, thick walls and perlite insulation."

[windage]

I will have to dig those up...!

[Alomran]

How high is the 81 inch oven's dome? Did you use a particular formula, or you just found it to be a convenient height?
Thanks again for sharing your knowledge with us.

Alomran, only cracks in the arch from being hit with firewood. Mortar recipes very early in the thread, wouldn't change it. No cracks in dome interior, baking 5 years now. Thanks for posting!

While the oven was so cool during our run of the mobile pizza van, I took the opportunity to rebuild the cracked brick arch on the big oven. Careless firewood "chucking" took it's toll with cracked mortar joints and smoke leaks. I dug out the original arch support template, removed and cleaned the tapers and reset them...even adding some brick to the hearth that didn't get finished at the build..

Hi, Well done for the great efforts. I am building an oven about your size.
1- What can you teach us about the cracks?
2- What sort of high temperature mortar did use?
3- Do you think the mixture you have researched was not the appropriate one? did you use hydrated lime with fire clay?
4- did you get cracks inside the dome or only in the arch?
We look forward to learn more from you. thanks again

thanks, RandyJ, but I have experienced way more failures than success. I just try to sort through the pile of failures as fast as I can to find a success.

Here is a project I started couple years ago, perhaps my biggest undertaking yet...the rebuild and refloat of a 60ft Alden Schooner...gonna be my "retirement home" a link to my page regarding that project.
