[Cob] Land search...pressed earth blocks vs. cob

[Amanda Peck]

Thanks.  You're right.  Not the end of the world to buy a used hand 
block-maker and then change your mind, but, one of those new-truck priced 
ones?

I would not recommend buying any kind of block making machine until you are 
sure it will work with your soil.

After I'd done a three layers of cob I was concerned that each layer was 
taking too long to dry but I've now developed a mixture of soil, sawdust, 
cement and lime which makes good blocks and even better mortar between 
blocks.  The cement and lime overcome shrinkage  and are firm enough to 
support another rise within 24 hours.  I'm confident this mix will be ideal 
for making my house walls.

Cheers

Lance
