[Cob] Slipstraw addendum (Mike)Monica Proulx mon.pro at gmail.comMon Oct 31 14:53:12 CDT 2011

Slipstraw addendum (Mike) > > > ---------------------------------------------------------------------- > > Mike, > Good question on the racking, glad you brought this up, I never thought of this. Doesn't metal in something like cob (or slip straw) = sweating? (as in not good with the clay/soil. I've no experience with metal in cob, just going by what I've read on this). Wood sounds better. Maybe you could use "let-in" corner bracing (less wood), instead of larger diagonal braces or Xed metal straps (image-google "let-in corner bracing"). For that you could use smaller plywood triangles (on the face, or do inside the framing with 2 by 4s). If you're wood to wood with the screws, no sweat! (literally). One would wonder if the dried light clay straw wouldn't provide the rest of the strength you'd need. > One more thing: > > A member of the list wrote and asked, given I'm not going to have any > sort of paneling, what I'd be doing for tension.
