Adding CalSil Insulation Boards - Wood-Fired Oven Hearth - Under Cooking Floor - July 2024

Image
A couple days ago, I posted details of how I am using sheets of tile (flipped upside down) to create a little drainage pattern that sits on top of the poured concrete hearth of our wood-fired pizza oven .  On top of that tile goes - first - insulation.  Then, the floor and dome.  There are a number of ways to do insulation, but over the past few years, the FornoBravo community has seemed to coalesce around the use of Calcium Silicate Insulation Boards as the *best* insulation.  I found some online - sold locally in Southeast Wisconsin - at a decent price.  I bought 54 square feet of 2" thick boards.  I've opted to go with a double layer - 4" of CalSil boards.  That's the recommendation for the 'best insulation' you can use.  Why insulation? To keep the heat *in* the oven.  In this case, it is about creating a barrier between the cooking floor and the concrete hearth.  From what I understand...if NOT for the insulation, the concrete hearth would act as a '

Building A Platform For Concrete Mixer - Pizza Oven Hearth - June 2024

A few days ago, I shared an update on our DIY backyard wood-fired pizza oven build that showed the latest progress:  the installation of the final rebar and bracing (wires) for the raised, reinforced concrete hearth.  I'm set to pour that 4.5" thick hearth (plus the filling of the pressed bond beam block cavities (so...around 8" deep around the perimeter and 12" deep across the opening spans), but the forms of the heart sit 42" above grade.   Like I did with the foundation slab, I'm planning on using the MudMixer to help pour the concrete.  The problem that I'm facing is that the Mudmixer's chute stands just 16" from the ground.  That means....that I have to either use buckets to lift the mixed concrete up from the Mudmixer chute or....raise the Mudmixer to allow it to 'POUR' directly into the raised hearth. If you look back at this post where I showed the foundation slab pour, you can see that I made a platform for the Mudmixer to allow

Mortaring In First Course - DIY Pizza Oven Construction - May 2024

Last I posted about my backyard DIY pizza oven construction project, I was showing the foundation slab after I had stripped the forms .  The pour went well - thanks to the MudMixer.  Now that the reinforced slab was done, I can move on to building the stand.  That stand is made out of 8x8x16 cinder blocks.  If you go back and look in the archives, you'll see that I went back-and-forth about the dimensions of the slab and stand and after a bunch of thinking/tinker'ing, I ended up deciding on these dimensions : Slab: 72" wide x 80" deep. Stand: 4 blocks wide x 4.5 blocks deep - 62.5" wide x 70.312" deep. Hearth: Same as stand. Oven: 39" interior, 51" exterior side-to-side x 64" front-to-back. That's the slab that I poured: 72" wide (6 feet) by 80" deep (6 feet, 8 inches).  And, so I could go about building the stand with four blocks wide and four-and-a-half blocks deep.   Setting these blocks square is important and I had to pl

Backyard Pizza Oven Construction - Foundation Slab and Stand Material Options and Details - March 2024

With excavation started on the site of our backyard wood-fired pizza oven (on our drywell) , I need to move from the theoretical (What could an oven look like?  How high should it be?  What would it need to be made out of?  How many cinder blocks? What layout?) In my recent post on excavation , I ran through some mental math to figure out what size the hole needs to be, what size the slab will be and how wide the block foundation will be once constructed.  I ran through both a 10x8x16 block scenario and an 8x8x16 block scenario.   The 8x8x16 is the traditional block, but I was considering if the extra 2" block in the first (one or two) courses is appropriate to all for the footing of a brick face on the sides of the oven. Off I went to Menards to poke around in the construction block section.  Back in January, I posted the details of how there are L-shaped cinder blocks that help make proper corners and I wondered if I should be using those to make a square pizza oven stand .    I

Digging To Find Drywell For Backyard Wood-Fired Oven - January 2024

Image
A few weeks ago, I posted a couple of items related to my 2024 goal of building a wood-fired pizza oven in our backyard including a look at a couple of locations , some brickwork inspiration and how I could build the stand out of cinder blocks - including corners .   With the snow melting away this week, I went out to look at one of the locations and remembered...that ahead of the snow, I was digging around trying to find the 'edges' of the drywell.   Below is a photo showing a number of locations that I dug down to see 'how deep' the drywell is located and how I was probing to find the 'edge' of the well.   The drop from grade to drywell is variable across this six-foot-by-six-foot section.  Surprisingly so.  I also found (I think) two of the 'edges' of the drywell.  Which...if I sited the oven where I *wanted* to, would have a small portion of the foundation OVERHANGING the drywell.  That would mean that I'd have to bring in some gravel - which i
