Northwest PA 36" oven build

Re: Northwest PA 36" oven build

Lots of progress since my last update.

1 inch of ceramic blanket over dome, covered by 2 inches of 7 to 1 perlite/portland cement.

Rough framing done. It was really fun to frame a circle.

Chimney mounted (I have another 24 inch section to add).







I was going to fill the structure with loose perlite after the walls are in but am having second thoughts. I have plenty of room for another 2 inches of blanket then fill the remaining space with loose fill. Before I take this route I just wanted to make sure I can do that over the perlite/portland cement layer. I know ideally The best insulation goes first but... Best laid plans.

Curing fires start next Friday Can't wait!

Re: Northwest PA 36" oven build

More progress. Getting the hang of how bricks and mortar work together... its getting fun.

Got brave after making the arch tonight and pulled the form as soon as the last brick went in.








My goals by the end of the coming weekend include Chimney, insulation, buttressing of the entry arch and hopefully some framework for the house. Sneak peak of what is to come...

Re: Northwest PA 36" oven build

The arch will definitely have a buttress. I will make one as I'm enclosing the oven. Decided last night on building a structure around the oven. Ordered the chimney and other needed parts last night. Super excited for the next part of the build.

I'm building a circular house around the oven with a hexagonal roof. The house will be covered with the stone I pictured earlier in this thread. Thinking cedar shake for the roof but have not made up my mind yet. I do have some very strait grained white oak that I have been thinking of splitting with a froe to make my own shingles. But time might dictate my materials usage. we will see.

Re: Northwest PA 36" oven build

Have you considered a buttress for the front arch?

The dome looks good, industry has its own reward.

Re: Northwest PA 36" oven build

Worked 9 hours non stop today... lots more progress



Closing in on the keystone



Keystone in and cleaning up the inside a bit. I just managed to fit ... This was definitely not fun!



inside the dome. Not that pretty but it will get the job done. I still have to go back out later tonight and scrub the excess mortar off.



Side walls to the entry done. I'll get the arch started ... maybe finished tomorrow night.

Re: Northwest PA 36" oven build

Made some more progress today chain 9, 10 and 11 completed. I think I can finish off the dome tomorrow and clean up the inside of the dome. Thats the goal at least.

I do plan on a little buttressing of the arches. There is not going to be a whole lot of weight on them.

Re: Northwest PA 36" oven build

Sorry for the question what is but buttressing

Re: Northwest PA 36" oven build

Gulf, I agree, I think there is some, but not much. Any vertical-sided entryway will benefit from buttressing as well, particularly if there is any considerable weight on it.

Re: Northwest PA 36" oven build

Please forgive me, if I am wrong, for adding more confusion. But, from the pics, I don't see much "tying in" of the inner arch and the dome going on here .

Re: Northwest PA 36" oven build

Greenman is correct. My error....sorry for the confusion.

Re: Northwest PA 36" oven build

The arch should be stabilised by the dome that it intersects with. The outer arch is where the buttress is needed.

Looking good.

Re: Northwest PA 36" oven build

Arch is not leaning. Its just the cheap lens on smartphone

Thinking of flying buttresses

Re: Northwest PA 36" oven build

Looking really good so far and at a record pace. It's hard to tell from the pics but it appears the sides of your arch are leaning outwards. You may want to check it more closely and maybe consider some butress on the sides of your arch. better safe than sorry later.

Re: Northwest PA 36" oven build

Finally got past the entry arch tonight (chain 7 finished). Pretty excited that side to side i'm within 1/8" of being level. Not too bad for not using an IT.



Hope to spend a few hours tomorrow night and most of the day Saturday working on the dome. I think I'll be able to close it up in less than a week. Not sure how I'm going to support the last few chains of the dome as I have not needed the IT and can't see myself making one as far as I have gotten without one.

Now if I could just decide how to finish off the oven. To build an enclosure or not... I see it finished in my head both ways and can't decide which one I like best.

Re: Northwest PA 36" oven build

You are building this at record pace....keep it up and you will be cooking in no time. Just get it completely done before you start cooking lol. Once you cook in it, your finish speed will be greatly affected
