Corbell Cobs

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.

Corbells
image
Grab a handful o' straw, all facing the same direction.
image
Spread it out in one thin layer.
image
I scooped out clay directly from the slaking bin.
image
Spread it all out over the straw.
image
Rollout up and squash and squish and squish it.
image
Slather the outside of it liberally with gooey clay.

And, Taadaa! Super strong corbell cob for arches and shelves!

Urbanite & Cob Bench

The Thermal Battery building has begun! That is, the cob and “urbanite” (repurposed chunks of sidewalk etc.) bench and bed the exhaust pipe is buried in. It will hold the heat and slowly release it back into the room.

More bench added

Bare pipe and piles of urbanite

Nathan made an impression.

Pipe exiting through the wall will not be visible after the bed is built.
