Re: K79 Oven Build

Wow, really looks great. I hope I can do as well. Cutting first course and starting mortar tomorrow. I'll be using your build for lots of info for sure...not that I haven't been following it for some time now

Re: K79 Oven Build

i like the shape, but is anything stopping those bricks from dropping? They don't appear to be supported or tied in.

Re: K79 Oven Build

Nice job K79.........I like the smooth transition........How long do you plan to wait before the curing fires start?.........No curing any time soon for me.......progress slow.......... Will try to close the dome this weekend

I've seen others that have done it this way and asked prior and nobody mentioned it was an issue. I read some threads and was unable to find anyone say it would fall apart. Each brick is one solid piece. Those tapers are cut into one brick. The front 3.5" of the arch is all connected and in compression holding them in place. All of my bricks are tapered really tight. Unless the front of my arch blows out and my tapers crack at their joints there's no way it's coming down. That, the buttress, and the mortar I think I'm all set. Not to mention before I even had the keystone in place the arch was holding itself up. No reason it should fall.

I'm waiting 28 days. My first fire will be June 29. Don't rush your dome. You'll get it done when it's done. I know easier said than done. Your's is looking good !

Re: K79 Oven Build

Why are you waiting? I built a fire in mine within minutes of finishing it, and had it fully cured over a week.

I think David means the bricks between your two arches that curve up toward your flue - which appear not to be tied into the arches on either side. Most builders stagger the center bricks into the arch on either side so they're supported by the arch, not just the mortar. If you built it without tying the bricks into the arch, and the mortar bond between the middle bricks and the arch bricks to either side breaks - then they could drop into your oven. Not saying it will. But I could see how it could happen. But then you also could have them sitting on top of your arch, which one couldn't see in that picture.

Seems a little conservative. I may have waited a week because of a short vacation. Came back and went full throttle out of the gate - zero cracks. There is no guarantee that time is the answer. I have a driveway that is 20 years old and it's getting cracks

Take a look at post #354 and #355. There are no bricks between my inner and outer arch. There is only my inner and outer. Those cuts you see I cut into my outer arch bricks.

Might be but I have so much going on here to keep me busy why not wait...

As far as your driveway... pavement is a little different than masonry I'ld say if you got 20 years out of your driveway thats pretty good, especially if you live in a freeze/thaw environment.
