2x8 Forms for Hearth Concrete Pour - Wood-Fired Oven Build - June 2024

Image
Busy week with the pizza oven.  First, the bottom trays and supports were put in-place .   Then, I cut, bent and placed some rebar into the top of the stand - via the bond beam blocks .  I also cut most of the grid of rebar.   That meant that I could move-on to creating the hearth forms.  I used 1/2" trays and I'd like the hearth to be 4" or so thick, so that means I need 4.5" of height on-top of the stand.  Because of the Bond Beam blocks and their openings, I also need the forms to cover 1.5" of the stand.  That's 6" of form - which means I can't use a 2x6, but had to upgrade to 2x8's. I cut the 2x8's to length, then affixed a 2x4 to the face of them to stiffen them - and prevent bowing.  I used various pieces of lumber to create legs that were just a tiny bit short.  I put the forms together, stood-it-up on the legs and then shimmed in one side for the final height.   Moving around the stand, I leveled up each side using shims to get the

Cutting and Bending Rebar for Flow-Thru Bond Beam Blocks in Pizza Oven Stand - June 2024

Image
Earlier this week, I updated my wood-fired pizza oven build progress with some photos showing the bottom trays and their supports/bracing cut to size .  I have a couple of things that I need to do (I lifted eight steps - bracing for trays shimmed, rebar to bond beam blocks, fill gaps, cut rebar for grid, set up 2x8 forms, wire them, add drainage pipes and fill remaining cores with sand ) and most of those can go in any order.    Once I had the trays in place, I decided to see if I had enough rebar on hand to complete the job.  That started with bending some of the 1/2" steel rebar for around the bond beam blocks.  Then, I cut the rest for across the top in a grid pattern. Below is a photo showing the rebar bent and laid into the bond-beam blocks.  I'm doing curved rebar at every corner and doubling-it-up with 90-degree corners on top of those curves.   On top of this will be a 4.5" thick hearth, so the rebar you see running across the top of the stand will be stood-up wit

Adding Bottom Tray Support Under Hearth Pour - DIY Wood-Fired Oven Build - June 2024

Image
The next step after filling every-other-core in my DIY wood-fired oven build is to create the support that goes *under* the hearth that can support the concrete pour.  I've made three areas for storage in the stand, so each of those need a cover (or lid) and some support bracing to keep the concrete from sagging through the openings.  I opted to use 1/2" DensShield board and various 2x4's and 2x6's to create the supports under the openings.  Below are a few photos showing how I cut the board (1/2" thick) and then used the legs to support/span the openings. Below is a peek at the INSIDE of one of the storage bins and you can see the legs/supports laying this-way-and-that.  Why?  Because...I cut them just a little bit short of the length needed.  My plan is to use a bunch of wood shims under these so once the pour is complete, I can pull the shims out and the supports will fall away.   Without the shims, the supports might not come out so easily.   Also, I'm us

Brick Exterior Exploration - Pizza Oven Build - June 2024

Image
My brain is already moving ahead to the exterior of the pizza oven.  I don't know if I'll get to cladding the outside of the oven, but I'd like to try this year.  You can go a lot of directions, but the one that I've focused on/been drawn-to is brick.  I've talked about brick and used a TikTok as potential inspiration for a brick pattern . That means that I've been poking around Facebook marketplace and Craigslist to figure out what kind of brick is available.  Every listing quotes the number of bricks available, but I had no idea how many bricks I actually need to clad the full oven.   In terms of oven facade inspiration, I'm very much looking to this oven build on YouTube as inspiration .  That oven is from the YouTube channel named:  The log cabin life style by Jerry Tyson .  This screenshot below is from his oven-build video ( source ) and I'm eye-balling the height of his corners to be five-feet-tall.   I know my stand is 70 inches deep by 62.5 in

Drystacking Pizza Oven Stand And Filling Cores - June 2024

Image
Last week, my pizza oven build update included how I had purchased a 10" wetsaw and mortared in the first course of the cinder block stand .  On top of that first course of block sits the rest of the stand, but I opted to simply dry-stack them in place.  The height of the oven floor is one of the biggest build considerations and I'm aiming for between 44 and 46 inches in height.  Based on some tests, that's where I'm comfortable and want to aim to hit when I build the stand, add the insulation and place the floor.   The floor is made of medium-duty firebricks that are 2.5" thick.  Set on a thin base of high heat mortar and/or sand.  Call it 1/4".  4" of insulation below that puts me at 6.75" of height.  The hearth has a little bit of flexibility in it - thickness-wise.  But, call it about 4 to 5 inches thick.  That means, I needed to do a little math to figure out how many courses I needed to build.   46 inches minus 6.75 inches = 39.25".  Sub

DIY Pizza Oven Build - 10" Wet Saw - Tools Needed - May 2024

Image
So far in my diy backyard wood-fired pizza oven build, all that I've talked about/posted about is what I'll call infrastructure.  That's the foundation slab (reinforced), the block stand (cores filled) and the suspended hearth (reinforced).  But, once all that is out of the way, it quickly becomes a brick-cutting exercise.  Medium-duty firebricks are 2.5" thick, 4.5" wide and 9" long.  They're beefy.   Each of those bricks require 4 (or so) cuts to make them useable in the dome.  In order to cut those big firebricks, one needs a saw that is both ready to cut brick (wet saw) and has a big throat (cut depth), so you don't have to cut one-side, then flip, and cut the other. After bouncing around Facebook Marketplace and Craigslist for months, I decided to take the plunge with a new saw from Harbor Freight.  Between their Memorial Day sale, another discount (membership) and a gift card that I was given for my birthday earlier this year, the new 10" D

Couple of Wood-Fired Pizza Oven Hearth Construction Tips Via YouTube - May 2024

Image
Last week, I posted my latest update on our backyard pizza oven build where I mortared in the first course of the cinderblock stand .  I'm on my way this week to swap out some of the blocks and to pick up the rest of the angle iron so I can drystack the rest of the stand.  At risk of getting things out of order, I'm going to talk a little bit about the suspended hearth.  That hearth sits ON TOP of the stand.  It is reinforced concrete that is framed up with a 2x6.  That means - at the VERY MOST, the hearth is 5.5" thick.  But, because you overlap the forms with the block stand, you lose about an inch - so it becomes something like 4.5" thick.   I'm thinking about the hearth and the materials required as I run to the hardware store and I found a bunch tips that I'm going to use in my hearth build via the  Blood Sweat and Beers YouTube channel  -  this video where he walks through his reinforced hearth forms and setup .   I thought it was worth documenting here

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

Image
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

Stripping Concrete Slab Forms - DIY Pizza Oven - May 2024

Image
Just 48 hours ago, I shared the details and photos of how I poured our backyard wood-fired pizza oven reinforced foundation slab using 46 sixty-pound bags of 4000 PSI concrete and a MudMixer.  I've kept the slab (mostly) wet using a garden hose and covered it in plastic.  48-or-so hours after the pour, I knocked down the supports and began to remove the forms.  Here's what was left:  an almost (for a first timer with a non-super-discerning eye) perfect 5.5" thick reinforced concrete slab: The light color (and discoloration) is from the plastic sheet touching the concrete as it cured.  I'm not the least bit worried about that as I know the slab will continue to change color.  I'm happy with the straight lines and the lack of air pockets around the edge.  I used a heavy hammer to vibrate the forms in an attempt to get the concrete mix down along the edge/face of the forms.  It seemed to have worked.   After a few more days, I'll get out there and snap some chalk

DIY Pizza Oven Foundation Slab Pour - May 2024

Image
After bending and installing the rebar, reinforcing grid and vapor barrier , it was now time to pour the foundation slab for our diy backyard wood-fired pizza oven.   As I posted about last week, I shrunk the foundation slab down to be 72" wide and 80" front-to-back.  It is 5.5" thick (2x6's for concrete forms).   This is sitting on top of six inches of 1/2" compacted gravel and a 48" deep of large rock drywell.   I used an online concrete estimating calculator tool and when you put those dimensions in, it says that I needed 42 60# bags.    I have to pour two slabs - this foundation slab and then, once I build the stand, an insulated hearth.  Each approximately the same size.   When adding those two up, I ordered 85 60# bags and had them delivered.  I opted for 4000 PSI concrete - as a little bit of an upgrade over the baseline concrete. Knowing that the labor involved in this pour is in two parts, I opted to split them up:  first...hauling the concrete
