Thanks! That's actually ceramic insulating board under the oven, but it is a double layer. The variety I got, Thermo-12 Gold isn't rated to as high of working temperatures as some other alternatives (a mere 1200F), but at ~$100 per 27 sqft, it made perfect sense to double up on insulating board. Also, I can't take credit for the angled arch, as I borrowed the idea from Amac, who I think borrowed the idea from GianniF. Gotta love this forum, eh?

I resemble that remark! I think the cement bothers me more than the cuts because I'm so adept at banging up my hands independent of any masonry. Just today I managed to crush both middle fingers doing something unrelated to laying bricks. On top of that, I hardly notice a few more cuts!

Thanks! And your warning is well founded. I feel like I'm getting clumsier as this project goes on. I'd better close this thing up before I fall and really hurt myself

Ryan,

I went up 12 then the plug - it looks like you will need to do the same. Again, great work!

Edit... it looks like you are at course 11 right now - 1 more and you are golden.

Your build looks alot like mine. At this point I abandoned the props I was using to hold the brick in place and used an inflatable rubber ball to hold my final course (which I cut to half thickness). I was fortunate to have a 12"x12" piece of FB left over from my hearth. So my keystone was a large plug. It took a few hours to trim it down to size with a taper to fit the hole in the top of my oven but that included time spent to put an inscription on the side that would be facing the inside of the oven.

Like so many other parts of this project, there are many ways of getting it done and it basically comes down to the materials you have on hand, your preference and most importantly - execution. Good luck on the rest of your build.

Probably getting ahead of myself, since the next course should be a doozy, but I'm thinking ahead to the vent and chimney design.

I've had it in my head for a while that I wanted to do an S-curve sort of transition, (See attached pictures, front, top and back, respectively). As pictured, this would give me a roughly 9" by 6" opening to put a flue on top of. I'm planning on the chimney being at least 5 feet high to allow smoke to clear the deck.

Questions: Is that too large of an opening?? Or rather, is that more than necessary, such that I could have the full arch in front be thicker and thus stronger? If I go with this S-curve idea, will I need to buttress to support this arch, whereas if I just had an opening and built on top of it this wouldn't be necessary?

Cheers!
-Ryan

I like the 'S' curve. It looks very elegant. I acheived a similar though less sensual shape by cutting a single brick (for each side) at an angle (lengthwise) and then used the two peices to form a smooth transition to the flue. I think the fact that the two pieces had complimentary angles helped the aesthetics and it required minimal mortar to create the transition I wanted.

The 9" x 6" openning should be ok - maybe a little smaller than mine. I used a an 8" x 12" rectangular flue liner which measured 7 3/4" x 11 1/2" on the inside so I made my vent openning more or less the same size. However I built a 42" oven so I don't know if that has any bearing on the flue size...I doubt it should change too much. BTW my chimney vents very well with barely a puff of smoke escaping when I first fire it up. As soon as the chimney starts to warm up (5 seconds later) up the chimney she goes. She being the smoke of course.

I can't give you any advice on the buttressing though. I did not buttress my arch/chimney but I only have the weight of the clay flue liner resting on my arch. I will support the exterior brick of my chimney with a block and steel structure (next year .)

Whatever you decide to do I'm sure it will turn out very nice - based on the work you have already done. You're in the home stretch now. Can you say WFO Turkey for Thanksgiving?

Looking forward to seein the final product. If I remember right, Tscar posted some info on vent opening to vent size ratios. I just can't remember the exact link.

Quick question for the forum: I started trying to taper the bricks for my vent arch, and discovered that my saw can't handle a 9" long, 4.5" tall brick--the top of the brick bumps the back of the blade guard before the blade has made it all the way through the brick.

Occurred to me that I could just cut the bricks down, make them 9"x3" or so, and then both the brick would fit under the guard and I could probably do the tapers with one cut. This would mean that my arch was 3" thick rather than 4.5" thick, however. Any reason that would be a terribly bad idea?

Raise the blade up a bit, and you should be able to get through most of the 4.5" brick before hitting the hub.
Then what I did is flipped the brick around and eyeballed the bit that was left.

The problem isn't the hub (which is easy enough to get out of the way by raising the blade), but the very back of the blade guard, near where the water tubes connect. Not a problem for cutting a piece that's 4.5" front to back, but the full 9" brick hits it. To get the back of the guard out of the way I'd have to raise the blade up as high as it will go, at which point I'm only cutting half an inch of the brick :P.

Ah, I see. Still seems like you could flip the brick front to back
