Make pizza with a plasma cutter, a backhoe and a pile of mud!

Step 6 Chipping, Thieving, Mixing, Setting

Now that I've got my subsoil, I can fill the cement board box with insulation: glass bottles set in a mud-and-wood-chip matrix. (Chips don't hold or transmit heat, and they eventually burn out, leaving voids that also insulate.)

I made a bunch of wood chips, but the chipper threw its belt and started on fire. That was the tool gods telling me I had enough chips. Hmm, now for an instructable about replacing the belt on a chipper.

The night before recycling day, I drove all over town and stole everybody's glass bottles.

Then I tried to put it all together, but I kept running out of bottles and having to go out for more. Officer?

I left a four-inch-deep rectangular void in the center. The thermal mass will go there.
