A few more steps completed for the oven. I built a frame out of 2×4’s to set the plywood floor on. Over this plywood, concrete will be poured to form the building surface of the oven.
Next, I built the edges out of some old 2×8’s and a 2×6 standing on edge. These will frame the sides of the slab.
I’m not entirely sure why, but it seemed like a good idea to lay plastic over the plywood, primarily to make the boards easier to get out at the end. I’m really reinforcing my pack rat nature with this project, every scrap of lumber used thus far has been repurposed from the house build. The plywood I fashioned together from leftover triangles of 5/8″ OSB that in any other project would have been thrown out or burned a year ago.
The final step was to put in some steel reinforcement. I cut two strips of remesh the length of the top of the oven, and overlapped them, threading them over the upright rebars. I then bent the rebar down horizontal, and laid some additional pieces in a grid on top of the mesh.
It looks like I may get lucky and get some concrete on Thursday, my neighbor is pouring a sidewalk and I’m going to tack on a yard to the truck to fill the cells of my wall and pour the slab. Next up, I need some super-isol board for the insulation under the dome, and a whole mess of firebricks.
