WFO Build Underway!
« on: March 07, 2016, 02:10:08 AM »
I started my WFO build over the holidays and at this stage I'm well underway, hope to be curing by the end of March. I have a thread going on the Forno Bravo forum but want to get caught up here, so...

For starters, the plan. 36" oven with 9" soldiers and an elliptical dome, to be the cornerstone of my outdoor kitchen & deck plan:

A slight detour - Lori was concerned about how deep the back corner was in the wood storage, so I built a wall to cut it off:

Those pies look great.  The work on the oven looks first rate.

Looks awesome. How did you cut such a smooth, perfect curve into the template?

I love the attention to detail. What sort of brick are you using for the deck?

Thanks Craig. They are HC Muddox firebricks, pretty much the only thing that's available around here.

This was a decision I really labored over. Nobody knows if these are low- or medium-duty (turns out those terms were from a firebrick standard that was abandoned in the early '90s), but the manufacturer says they are 27% aluminum, and my pieces average between 7.5lbs and 7.75lbs, which by my reckoning puts them somewhere between low and medium. The reason I built around the floor instead of on top, is so that I can replace them if needed, but after laying the floor without a dome over it, I can say I really really hope I don't find the need to lay it again later.

Jigsaw and router. The bottom piece was just a string and a pencil once I had mounted the center pipe. Funny I was just thinking yesterday how that string is essentially the primary measurement the whole design is growing around. For the dome profile, I used my CAD program to draw the ellipse, measured the height on 1" increments, then connected the dots and cut.

I think that's right. According to this, 27% alumina - 2000kg/m^2 has a thermal conductivity of 1.05W/mK at 750F. http://www.traditionaloven.com/articles/84/firebricks-heavy-dense-fire-clay-bricks

Whitacre Greer cites something like 0.7W/mK, but that's at 30C. I don't know why they measured at such a low temp. Conductivity increases with temp, so these are probably similar at operating temps. I've baked on WG light-duty fire brick, and it's conductivity is definately on the very high side of acceptable.

A couple lay-over options are discussed here: http://www.pizzamaking.com/forum/index.php?topic=22618.200 What he did to fix his overly conductive (1.5W/mK) deck worked really well.
