Making a wood burning oven



Our goal:
    To make first rate pizza, bread and roasted mammal components

Our solution:
   Build a 36" diameter wood burning oven

Why wood burning?

1) We live in a forest
2) Wood smoke tastes good
3) We had a boat load of bricks from a chimney we demolished when we remodeled the house

Our story...
So I made a brick box like this

Add Support structures 

6 inch I-beam I had left over from a job                                 Temporary supports for concrete pour


This concrete slab that holds the oven up is going to get hot and that will make the slab expand. I don't want it to push on the walls of the brick box and possibly break the box so.....

First we cover the top of the bricks with 2 layers of 6 mil plastic to start making a slip joint

Then add some spacers made from foam insulation to keep 
the concrete 3/4 inch from the sides of the brick box


The foam will need to come out later so I tied mason line to some 1/4 inch 
dowels so that I could pull it out after the concrete has set
* I'll let you know how this works
Update ( The foam spacers came out perfectly naturally...hehe)


And covered them with duct tape to keep the concrete out


Next I added 1/2 inch Hardie board to fill the space between 
the I-beam and the blue spacers. 

Next comes a mat of rebar 

And a form for the concrete

Making a wood burning oven "The Pour"

We are getting ready to pour the hearth slab. First we did a few things to get ready:

Blocked up the mortar tray so we wouldn't have to bend over so much


Blocked up in front of the mixer so we had a level place to stand at a good height for pouring concrete out of the bags


Duct taped the seams so we would have fewer drips and puddles


Made a couple of screeds to rough level the concrete


This product wants about 2 1/3 gal water per bag so we marked a bucket accordingly

Mix Mix Mix

Pour Pour Pour




And three hours later, there you go

Say good night Gracie, we'll see you in a couple of weeks


And now for something completely different...
