| Here is yet another way to determine hinge action at the 45degree/follow-thru/both arms straight location:
The SCORE LINES point AT the left shoulder = Horizontal Hinge Action
The SCORE LINES point STRAIGHT ACROSS the plane line = Verticle Hinge Action
The SCORE LINES point "In Between" these two points, but on most planes closer to the left shoulder, for Angled Hinge Action  |
