[Cob] roof trusses

[David Knowlton]

if you want to preserve the aesthetic and you are patient you could make the
purlins (cross pieces you attach metal roofs to) out of split logs. Remember 
to
align your metal so you are attaching into virgin wood and not running into 
the
fastener you use to hold your split, or notched rail, to your log trusses or 
rafters.

make drawings and build models - it's cheaper and loads of fun.
