Duane's 42" Build

[Hamilton]

Hey Ricky I forgot to say thanks for the help with the signature.
Thanks.

[Hamilton]

Good morning.
Made a little progress this past week or so. One more course and I will be ready to put a plug in it.
Have attached a few photos showing the progress and also a couple of others.
One of the photos is of the suspended slab after I had removed the plastic after 6 days of wet curing, it was was streaked up from where the wrinkles were in the plastic.
The other photo of the slab is how it looks now when you get it wet, I kind of like the look.
I am wondering if there is any way to maybe seal the concrete that would brighten it up and keep the moisture out?
Not sure why it looks like it does, looks like maybe the sand in the mix came to the top creating the light colored veins, but I do like it.

I need to figure out how to attach a signature that links to my build/photo gallery.

Goto your profile by clicking the right top picture with your name and choose user settings. Click account tab and then scroll down until you see edit post signature.

Sweet build you have going on there. Very clean work.

The reveal is right at a half inch on the right side and 5/8 on the left, not sure how I managed that. A wider reveal would be one of the things I would have approached differently had I done a little more research "creeping" before hand.
Will just need to make it work at this point, sell the house when I'm done and try it again. lol!

Hey guys.

Temps are coming up, finished up row #9 with bricks that were cut before I had to shut it down for the winter and set a couple of anchor bricks for #10
Bricks are cut for course 10 with the exception of a couple that will need to cut as I get there.
I have spent the last couple of months creeping in the background and looking at some of the archived builds, wish I would have spent more time creeping before I started this project, my approach would have been a bit different with the build.
I think it's going to be alright though!

Here we go!

"Alright"!?!?! It's a work of art! Only thing I can spot which may be an issue is the photo does not show much of a door reveal, i.e. a "step" between your inner arch and outer arch to allow you to place a door and seal the opening.

Hey guys,

Thanks for the kind words.
Mark I ran across your last build with the re-purposed heater bricks a few days ago, to cool!

Thank you Duane. I've only built the one! Some others here have built multiple ovens.

Russell your build, the artistic detail coupled with the craftsmanship throughout every step of the process is just amazing to me, you can tell it was very well thought out.
How many ovens have you guys built?
Going to go ahead and drill a few weep holes form the bottom, but given the way I built the stand I can only access the front half of the oven, will have to hope that will suffice. The foil was used to keep the calsi board from getting wet and soaking up water from the castable so it would cure properly, never thought about it being a problem.
I think I understand the use of a heat break, keeps the heat in the oven where it needs to be and not losing it to the front where you don't need it and don't need it or want it.

Nice brick work, you spent A LOT time doing tapers and bevels for the tight mortar joints (I know from experience). I would second Gulf's comment on weep holes especially since the CaSi sits on the concrete hearth. Nothing you can do about the aluminum foil now but for future builders, IMHO, I would skip the foil since in can also keep water in as well. Wet insulation is one the the most common issue poor oven performance. With the extra thermal mass, it will take longer to heat up but at the same token stay hotter longer once the floor is saturated. Keep up the good work.

[Gulf]

Thanks Duane,

Gulf is just a username, "handle" or internet guise, carried over from years ago on other forums. I go by Joe. In years past it was a little more distinguishable in my signature (lines). The forum used to allow multiple lines in the signature. Now I have to kind of squash it all together on just one line.

I don't know a lot about refractory castables. There are others on the forum that do. However, many bread bakers do want the extra mass under the brick for extended cook times. That's ok as long as you ae ok with the extra heat up time.

Weep holes and elevating the insulation off of the structural hearth are fairly recent ideas that help against moisture issues. Heat breaks are more of a debatable topic. Though, I am sold on the idea.

The foil you have between your castable layer and the insulation may be an issue trapping the moisture in the insulation layer. You may want to drill some holes through the structural hearth up to the insulation layer. You will probably get other comments from those that have advised and/or have done this after the fact.

The moisture issues are mostly a problem with folks who have uncovered igloo style ovens in inclement weather climates.

I'm not familliar with the Raddo CDs ?

Wow! Duane, that's one of the neatest brickwork builds I've seen - ever!
Well done.

Kind regards,
Mark

It's Duane, Frank is my first name, my dad's name, I've always gone by Duane. Is it Joe or Gulf? Just checking out your album, I am not as artistic as yourself and Russell? "Bee Hiver". The layer above the insulation board from Forno Bravo is actually a refractory castable. "Heat Cast 40". I just felt the need to add a little more thermal mass under the floor to match the walls. Wrong or right I don't know, just winging it.
Seems to be a lot of discussion about weep holes and heat breaks lately, that I have not been aware of in the past. While I have researched this off and on over the last decade and have an unwatched CD from Raddo? somewhere here in the house, these are things I am just finding out.

[Gulf]

Hamilton, Duane, or Frank?,

Great web alum! That's a very nice and clean looking build you have going there. The only question I have is why you placed the p/vcrete on top of (I'm assuming) better insulation?

Good morning
Here are my photos. Thought I replied to this thread but I guess I started another post earlier this morning. Take a look and let me know what you think and any concerns you might have.
Really thought I would be cooking by now. Getting cold out, will do what I can when I can through the winter months.
