It was a Maine morning of slush, ice, snow and general glop, but there was work to do.
After the tarps were pulled off, I insulated the oven with cellulose and then covered the top with a spiffy metal roof.
Where there are some small gaps and imperfections in the oven facade, these will be filled with bread dough. I did say this oven would not need mortar or mud, but I didn't say anything about dough.
There is still work to be done on the tongue, a door must be constructed, as well as a heat shield and something has to be done about the nude plywood. Maybe cedar shingles or simply paint.
