Mike McDonough and Greg Allen, Cob Cottage Company apprentices and expert cob builders, show how to "plumb" a cob wall to make it vertical.
This was part of the instruction at their 7-day intensive cob building workshop in Durham, June 2012.
Tools needed: level, machete, and cob saw (optional). A "cob saw" is just a regular saw with larger teeth cut into it. Use a metal grinder to cut the teeth for your cob saw.
