[Cob] Next step

[Janet Standeford]

Hi Damon,
Actually the dirt is dampened and fed into bags already in place on the 
wall. Coffee cans can be used, then the bags are jiggle tamped. That's 
actually a lot less work than cob and it provides thermal mass.
 If my calcs are right the 840 kN/m Kathy mentioned is equivalent to 
188,000 lbs/ft so with a wall only 20 feet high, there is no way the 
bags can burst due to pressure.
Also, jiggle tamping damp earth  in the bags should, per some sites I've 
seen, create a more rammed earth effect after dry.
If I'm wrong on this please let me know everyone.
