I understand why some asre asking what equipment. We just want to know how this company is doing it? It would help him to post a pic of the tooling to ease some minds and sell his services. I am NOT asking to put down this new company or anything, but like some said, the Ole Pipe Clamp method is not what I would want used.
I wish this new company the best and I hope he does well. The economy sucks and it is tough for many of out there including us. Questions should never be construde as "blasting" a company, but I agree those questioned can be a asked in a more polite manner.
My only suggestion to Renew would be for them to be as forth coming as possible to build the trust of their customers and they will do great.
Again, good luck to RenewRC.
