I am giving a second oven a lot of thought....
How would you design a portable oven?
I want to build a 42" Pizza oven that's strong but lightweight (relatively) essentially using the Pompeii plans. Maybe we can do an lightweight version??
I want an oven that can be picked up with a forklift so I'm focused on the 48-inch reinforced hearth at this point (will consider a stand and/or trailer later). I can just slide the oven into the back of my pickup for now...pizza to go!
Here's what I'm thinking...please comment!
The first element to me is the most critical as it needs to be stiff. It will look a bit like a pallet as I want to pick it up with a forklift. In fact I'm going to disassemble a pallet to use those side wood pieces for a form with the two tunnels.
The first layer is going to be reinforced and round, just bigger than the oven dome. I'm wondering how to best strengthen it. Ideas? Is steel mesh different than rebar? What about a double layer of mesh in the middle of 3" of concrete, separated by an inch? Are there stronger mixes of concrete to consider? Any lightweight options? What about fibers of some sort?
The hearth will follow existing plans using 2" FB board and firebrick. I'm not thinking about cutting corners here, should I?
Now the dome, would you start the dome on the hearth or on the slab? I've seen discussion that on the slab is better but I thought the hearth ...is there much difference?
Build the dome out of 1/2 bricks, put on their side. With a good FB insulation blanket, I think that will work. But would a 1/3 brick be better/stronger? Not that big a weight differential.
A layer of FB mix over the dome, FB Blanket and Vermiculite concrete...
Sounds simple enough....
I'm most concerned about how to minimize cracking when moving.
For now it's the perfect virtural oven.... at least in my head!
If you were to do this, what would you be doing?
There are enough good minds here to get it right!

PS...Any estimates on weight?
