[Cob] traditional building, sort of

[Gergo Szekely]

It sounds like an interesting idea to me. I am just wondering if you still get 
the same bound between the previous layer and the layer you have freshly put on. 
For some reason I have a feeling if there is a larger amount of fresh cob on the 
wall it could be harder to work the two layers together and create a good bound 
in between them.

How do you feel about it?

I've been using the pitchfork to heave the cob onto the wall. After I throw 
several heaps up there I climb up on the wall and walk around on it, letting it 
splooge out the sides if it needs to. I go back a day or two and slap it down 
with a 2x4 to the shape it should be. This goes surprisingly fast. I don't work 
on it much though, so I have no idea how much I could put up in a day. I have 
really noticed how important the straw is while using the pitchfork. If there 
isn't enough straw the mix just slips through the tines. I haven't done the 
mixing with the cattle because I don't have any. I mixed a huge pile of cob with 
the bobcat in about 10 minutes, which would have taken me several days, and a 
lot of labor, to do by the tarp method. All you have to do is get the 
proportions right, so if it dries out a little too much, just wet it down and 
stomp on it to pack the clay together and it's ready to build with again!
