Most cob builders use a form to make their arches perfect. We, as you can see, did not. The windows are wonky. We like wonky. (Yeah, one pane is broken due to construction mishap.)
To make the arch over the windows and doors, we need to use super strong fiber straps made of sticky clay and straw. The arches distribute the weight of the wall evenly over the openings.
Part 3: Insulation and the Barrel
Under that slab of marble is the manifold. It’s a space between the bottom of the barrel and the first length of stovepipe.
I left for the day and returned to a blazing fire in the cob house! Pah!
Our first batch of cob for the season started the coffee nook. The large, opening, SSE-facing window will be set in a small wall of cob atop a salvaged marble sill. In front of that, a fir slab counter. The foot of the bed (nest-shaped and heated from the exhaust of the rocket stove) will serve as a bench. A”coffee rocket” will be built right into the wall next to the window. So, sliding out if bed for a cup of coffee is that: just a slink under the covers to emerge in the other side, light up the rocket, and grind the beans.
