Cob: slip formed walls

[Charmaine]

the method described was not exactly right.

with slip form stone some precision is needed.  bottomless wall 
formworks are made of wood,  then stones are placed  facing best side 
out (to outdoors) and IN if to be facing interior, then a cement mix is 
poured in  the middle and left to set, then the forms removed and moved 
up and repeated, this is very heavy work depending on rocks used, and 
mistake happen but you don't see them till after the forms come off.

Making a flat poured wall of whatever materials, even conventional, then 
facing it with  stones that are sliced in half, or flatish, or heaven 
forbid those phony "rocks" that my bank used, can be just mortared on. ( 
of course you can cast your own "tufa stone " rocks as needed for 
special fit too)

The video Art of Slipform Stone Masonry shows a way to make the walls 
against a  INSULATED wall as the inside form, and so walls are built 
from the outside view only. they sheet rocked the inside, but other 
options are there too for clever folks.

IN any case the old book by the Schwenke on Build a Stone house is not 
longer in print, Ken Kerns Stone Masonry is  good  for some wall build 
info, and "Living Homes" gives the same stone wall info as the video 
mentioned.

ya know I wanted to comment that with all the complaining about "get 
back to cob discussion" I find I see/ or receive very little feedback on 
 topics such as tractor cob or turtle cob or even stone use...are folks 
just reading and not participating???
