Hi Rogerio, There are two ways to learn this information. One is ot read and understand the articles published by David Stanwood and the other is to come here and take his one week course. Coming here is expensive and the course is something like $3,000US, a lot of money. The principals are relatively simple, the ideas are only unique in that David has been able to study the action and get some understanding of how it actually works. He has spent years evolving his data and refining his approach to the work. His course is really worthwhile because you will go away with such an understanding that the doing is extremely simple. Two foreign people, one from Holland and one from Norway, have taken the course so no one is excluded. You can go do his web site and get a lot of information there and you can search for and read the articles I mentioned. I learned from David very early on and have kept up with his technical approaches but not the specific techniques he uses. I am not stupid so I have been able to figure some of his things for myself. Happy New Year to you and your family. Newton
