[Cob] Looking for answers

[Henry Raduazo]

My solution does not do much for the lifting part, you still have to lift, but it makes a great difference in the mixing part. I do my mixing with a 5 Hp front tine rototiller. I was able to mix and build an 8 ton wall in 8 non-consecutive days with one assistant. The problem with tiller mixing is that the cob is too wet and soft so after building 6 inches to a foot I needed to stop for a few days to let the wall dry out. If you want to work on weekends this works great. two days of building and five days to dry out. The only caveat is that you need one of the cheap front tine tillers not the expensive ones with powered wheels because you need to go back and forth on the pile. Sometimes you need to pull the tiller backwards to drag dry material into the wet.
	I have pictures and a more detailed description for those who are interested.

I do NOT want to spend 13 years building it for instance and do NOT want to mix all that Cob in the traditional way by myself etc.

I plan to use some combo of Cordwood, Cob, Earth Bags, mechanized mixing/foot mixing, local natural and recycled wood to accomplish my project. Not hinging ALL my hopes on collecting a large group of volunteers and doing everything traditionally in terms of Cob.

> the work is backbreaking hard. especially if you have to lift the cob up to top of tall walls (our home is 2 story).   we've been working on our cob home, mostly weekends, for 13 years, I think we'll finally be ready to move in this summer.  we're working on interior finish.
> we arranged for workers to help because we can't do all of this physically ourselves.  one good point is that it's the type of work that doesn't require a lot of skill,  we used my young adult kid's and their friends who were in the late teens and early twenties - all unskilled labor.  it provided a chance for me to teach these young people regarding project management and sense of accomplishment and importance of sustainable design.  We provided lunch, sometimes dinner and had a lot of fun getting covered in mud.  we nickname the young guys and gals who lift the cob up to the cobber our mules.

> I have a few questions about Cob building. I hope someone can help me out or point me in the right directions. First off is I have a bad back. In fact I am on disability because of it. I can do minor things, but lifting heavy objects repeatedly is definitely not one of them. So my main question is, exactly HOW hard is it to build one of these? I love the idea, and love the concept. I would LOVE to build one of these myself but I am just not sure I am physically able to do it. I was hoping someone could give me an idea of exactly how strenuous, particularly on the back this process is. I do plan to get some help, and maybe they could do the bulk of the heavy stuff but I am just not one to sit around and watch and most likely would try to jump in and do some things I will regret the next day. I dont want to continually be doing something thats gonna lay me up for a few days before I can jump back into it. Now for my next question. I am in North Carolina
> and have been scouring the internet for some workshops here in NC. I found one but the scheduled date for it was like 2011 I think it was, several years ago:) So I think I missed that one! Does anyone know of some ACTIVE resources in North Carolina that I could get up with? It seems everyone I have found online have not been around very much in the last year or two. I apreciate any and all help I can get on either of these two subjects!
