[Cob] Washington, DC

[Thomas Gorman]

Ed-
At some point can you go into more detail about the tiller cob  
mixing?  I'm planning an eventual, partial-cob structure on the  
property I'm in the process of buying (48 acres) and my father is all  
excited to have a new home for his now 25+ year old rototiller.  He  
insists it still runs great, though the last time I remember seeing  
it in action was many, many years ago....  I don't have the heart to  
tell him that the permaculture plans I have don't really call for  
much (if any!) tilling.  But if we could effectively use the tiller  
to mix cob, that's a different story!
