K79 Oven Build

Re: K79 Oven Build

Oh man, why did I read that some people used low duty firebrick for their oven. I'm supposed to be using MEDIUM duty firebrick for my oven right....ahhhh Also the exact dimensions of my medium duty firebrick are 9"x4 7/16"x2 5/16". Dimensions ok?

Re: K79 Oven Build

Low or medium duty will both work well. People have also used high duty but I understand its a b*tch to cut and also takes a bit more work to get up to temp.

Re: K79 Oven Build

Do you follow the same principles as your dome when it comes to mortar thickness and your vent arches? Smallest joint possible or do you want a 3/8" joint here?

Re: K79 Oven Build

DJ is kind of right, about heavy duty which I used in my build, they are not only a b*tch to cut they are a #@$% b*tch to cut

K79 -
here is a sketchup of how I built my arch. Freestanding, and the "L" bricks are in the front. The Gray area is where the vent arch overlaps the inner arch. You'll see there is about a quarter inch difference.

Glad I saved...

Re: K79 Oven Build

So is it even possible to achieve an 8"x12" rectangular vent in your arch? Using an 8"x12" clay flue I would think you would want the exact dimensions for the arch vent which would equal an 8" round steel chimney. I'm also wondering how you would work the flashing around the chimney that comes out right at the peak. I've called supervent about their ss 8" chimney (thought about doing this) and they don't even sell any type of flashing for a chimney that comes out the peak.

Re: K79 Oven Build

A Few questions here guys: Ok, here is my plan for my arch. It's about 75% complete. I think the other 25% needs to be figured out on the fly. What do you guys think? In the front view I only show a set of green bricks on the left but they are on the right as well. Those represent the arch. Same with the green line. I'm planning on putting a 1" reveal around the inner arch for my door. Sounds like enough to me, but from experience is it? Are the bricks spanning the vent arch in the front and back with the dimensions of 2 1/2" to small to be structurally sound?


And for my enclosure the FB plans show 4" of space for vermiculite around the oven. I wasn't sure if there was some sort of code why they have the roof 4" over the top of the oven and FB blanket. Here are two options. I'ld really like to build the first one so it's not so tall, or do I need to clearance in design two?

Design One:



Design Two:



And Last, is just over a half inch mortar joint on the outside of my oven just for my soldier's ok? I'm worried if I taper them then they won't fit nice and tight on the inside.

The adapter plate for metal pipe is 12x12, and requires an 8x8 opening to work.

Soldiers again! Do a search on using soldiers for the first course. Structurally unsound IMO.

This is the first I've heard of that and I've posted my build for about 2 weeks now. That's upsetting.

Re: K79 Oven Build

K79, I understand how soldiers might be less sound, I built my oven several years ago and have soldiers and have no problems. No cracking in this area and when I built it was a question of preference. If you use soldiers you'll have a bit more room at the edge of the floor. IMO as long as you build with care your oven will be fine with soldiers.

Re: K79 Oven Build

I do not see any difference between 2 courses of vertically stacked stretchers and a solider course as as it relates to outward thrust imparted by the dome. Parge the exterior when you are done and it should be GTG.

A sailor course is different though, it has to be reinforced or buttressed.
