although i did not read this whole post, i would have to say i disagree in saying that ANYONE can do it, its is without a dought a form of art. just because you read and understand literature dosen not me you have the capabilities to create the correct angles and have a steady enough hand to cut things. yes education is a tool envolved in doing it right but theres more to it then simply reading and understanding dynamics.
to anyone willing to learn i give all the props in the world but i cant afford to ruin motors the learn, or buy the tools for that matter.
