[Primitive Technology: Mud Bricks] (Viewer #16,414,562)

I’m impressed at how precisely he could carve a mortise and tenon joint with a rock. Seems like it would’ve been easy to slip and break one of those pegs off.

However, he had some other troubles on this one. From the description at the link:

I made a mixture of mud and palm fiber to make the bricks. This was then placed into the mold to be shaped and taken to a drying area. 140 bricks were made. When dry, the bricks were then assembled into a kiln. 32 roof tiles were then made of mud and fired in the kiln. It only took 3 hours to fire the tiles sufficiently. The mud bricks and tiles were a bit weaker than objects made from my regular clay source because of the silt, sand and gravel content of the soil. Because of this, I will look at refining mud into clay in future projects instead of just using mud.
