[Cob] Mix

[Janet Standeford]

Understood. But I'm getting this permitted and they want to be sure the 
insulation value is there and short of putting regular insulation into 
the wall I don't think I can convince them to let me do it with narrower 
walls. If anyone can get me true r and/or u value for cob, let me know.

Like the idea of the front tine tiller or cultivator. There should be 
quite a few people here working on it. I'm going to get the high risk 
youth out here with OIT so the kids can learn another way to build as 
they are already doing stick built.
