[Cob] CINVA ram

[Dean Sherwin]

excellent job.  Good workshop skills!  I know this is an old design, 
that was designed originally specifically for stabilized earth 
blocks, I think;  from these photos we can see why stabilizing 
(adding usually emulsion or cement) is advised, for keeping the 
blocks in good shape during manufacture and transport.  Once they are 
in the wall, just like cob or adobe, the wall can be protected and 
deterioration will be much less.
I've also seen them used in Indonesia for turning out cement 
('cinder') blocks.  In that case the maker was saving a good bit of 
the precious concrete mix by hiding a large stone in the center of each one...
An architect in Nepal told me these rams are too slow to be really 
useful and competitive.  How long does it take you to turn out blocks?
