Finally I am starting to develop a better understanding.
 

I have been hard at work and I am finally starting to understand things alittle more. Many of you may have seen my post where I was confussed on some issue about shoulder plane and plane shift. Studying 12-2-0. I have realized that this leads you to 10-6-B, which I now understand, You must also understand 10-13-A. These components and variations are very valuable, and I would point anyone new to TGM to these.

I believe that far to many people are trying to turn there shoulders on the rotated shoulder plane.
