Looks great to me! We have similar designs! Do you feel the need to buttress the arch walls?

I'm stuck in the same rain delay The angle/bevel changed for me on each course by just a little bit. I found that by the time I reached the top of my dome that I was "custom cutting" them. They fit better than my calculations and went faster. Since I'm not a master mason my plans on the computer deviated at some point when they were translated to the real world

Is there a specific placement of the inner arch so it will intersect with the dome.

I made my dome intersect with my arch. I think that's what lead to a little "misshape" at the top of my arch, but I took that out within two courses of brick over the top of my arch. I think if you do a design like mine you're pretty much at the mercy of the inner arch.... not much you can do. If you constantly use your IT you can adjust a little as you go all around your arch. If you don?t use it and match into your arch so it looks good by eye, you?ll really be off once you reach the top.

Re: K79 Oven Build

Ok guys so someone made a comment about one of my brick cuts way back when I was tieing my rings into my inner arch that the small thin cut I made would crack and fall off. I'm concerned that the same might happen to my outer arch design. My main concern is with brick 4 (labeled on the paper in the background and on the top of the brick in my photos). I'm angling my outer arch to have a nice taper to my vent opening. I'm just worried that my outer arch will crack and fall apart. I have 3 1/2" of brick that will always form the arch (the part that isn't tapered). Bricks 5,6, and 7 will be 3: 3 1/2" bricks leaving me a 5.5" vent opening. Please tell me these cuts are ok

Re: K79 Oven Build

That is some serious fancy cuts.

Reminds me of a joke, a guy is cutting bricks for his pompeii pizza dome, and suddenly he has cut off all his ten fingers. He rushes to the emergency room, and the doctor says, "no problem' I can sew them back on and you will be good as new. Give me your fingers"

(wait for it)........The guy says," I didn't bring my fingers, doc"

The doc asks why not?

The guy says, " I couldn't pick them up!"

Re: K79 Oven Build

Thanks guys. I was able to get 4 bricks on the left of my arch done and 3 on the right before I ran out of mortar. I'm taking off Thursday from work to finish it up !!

Re: K79 Oven Build

Ok, so the plan is to put on 3" ceramic fiber, then do my curing fires (hoping it will extract the moisture evenly with the blanket on), and I'm going to burry it in vermiculite. I noticed a lot of people doing a vermicrete mix... is that because they stucco the dome and not use an enclosure?

From the FB Plans:

As a rule of thumb, FB Blanket provides roughly double the
insulating value of loose vermiculate (and more than double
vermiculite concrete, which is less efficient). Here are three
roughly equivalent insulating schedules.


I noticed that boerwarrior bolted his anchor plate to his arch for his chimney. I was planning on just using some high heat mortar to hold it in place? Would that work... what to do??
