36" build in Tallahassee - AKA Bruce's Folly

Re: 36" build in Tallahassee - AKA Bruce's Folly

The molding clay idea is great. Way to think out of the box.

It might also work for other difficult cuts like at the inner arch transition or flue transition.

Do not worry about that hidden brick, the mortar will eventually fall into one of your future pizza's and you will again see the brick.

Well we have a dome happy to be the first to congratulate you!
I wouldn't worry about that mortar its V shaped so its not like it will drop in on anything I recon.
Would like to see some of the inside though. Yes I know its not like some of those perfect fitting brickwork ovens that we all seem to admire.
Myself If I was a betting man my money would be on little cracks in you oven. Those few extra gapes etc will I sorb the movement in the heating and cooling of you oven. Well there is only one way to find out.
So on to the insulation layer? Sparing layer?There seems to be a bit of talk about the importance of insulating in prevention cracking as well . I'm not sure but it wouldnt hurt.

Dave, Thanks for the congrats. Yes, I pounded the keystone in to the delight and cheers of the crowd, the popping of champagne corks, and the sound of trumpets. Well not so much any of that last part. I will attach pics to this post, fair warning, they aren't pretty (I'm referring to the brick work; not to me). Still I think the dome will support itself and I did keep the dome height right at 19". Still, having it to do over I would take down a few rows rather then try do it the way I did.

I think the next step is to add the extra thermal mass to the dome. Should I add anything to the refractory mortar (like stainless steel needles or firebrick sludge). After insulation, curing , and working out the entry. Somewhere in there waterproofing.

I hear it gives it that special DIY WFO flavor.

Gapes don't matter
Use stainless needles ..... I wouldn't bother the domes strong enough by its self to hold up the sparging layer. Firebrick sludge .... Don't know it would be the same as the dome for thermal mass I suppose as its firebrick. It would treat the propotions as for the sand ...the agregeate .If you using the store brought high temp mortar ... Perhaps not, as it would possibly effect the strength of the product.
Anyway there my thoughts on that. Again well done on the dome!

Nice to know my gaps are (as Microsoft would put it) a feature not a bug.

I spent this a.m. cleaning up the oven. I then tackled and the tile saw and I ended up with a bucket of sludge. Anyways here are a few more pics.

Kudos on closing the oven.........

Thanks.. I think I will start the cladding tomorrow. Still haven't decided on entry. Bruce

What are you using for dome insulation ? I was thinking of thickness of the insulation in relation to the current lip of you oven entrance

I will be using CF blanket. Any concerns?

Wear a space suit when handling it.

Like Al said those fibers are a concern so use PPE.
In wondering how you were going to marry the front of the oven and the insulation/ cladding. You'll have 2 in of insulation and 3/4 inch cladding? And doesn't appear that you have much of a oven lip to butt that too. Off course I'm just looking at the photos

Al, no space suit (sadly) but did wear gloves and a mask. I actually found it easier to work with the cutting the cf board.

Dave I am thinking I will end up with an entry. I loosely laid out the blanket and have at least 4 " with 5" on the top. I decided not to do the cladding, as feedback from the forum was basically go ahead if you want but not much benefit either in the thermal or structural departments. Open to suggestions on dealing with the limited self of the inner arch. It seems to me that an entry would solve the issue. I have a used 8" adapter plate that I paid $22 for. Maybe do the outer arch and install the plate . Know any good examples of relatively easy to build entries?

I can't think any any builds that go into much detail. Lately the most common entrance way is brick usually an arch following the shape of the entrance only bigger in size to leave a revel for the door.
What's your thoughts on what's a usable size in height and width for you in the chair? In saw the pics of you trying out the peel would I be right in saying the width would be better to be bigger?
One suggestion would be to extend you oven entrance by 1/2 brick to help you finish the insulation and render to allow you time on the entrance?
What are your thoughts

My suggestion would be to build the entry in semi-circle form. This shape will give you plenty of room for your door, good visibility, and is stronger than an arch with straight sides. As a plus, it's easy to build.

Only one brick length needed, the depth will be 9.5" or so.
