[12 piece bucket]

Its perpendicular, or at right angles, to whichever inclined plane your left arm is laying on.

By that I mean that if you hold your left arm, cocked wrist and all, out in front of you and horizontal to the ground with a club in your hand, the shaft of the club will be perpendicular, or at right angles, to the horizontal plane which your arm rests on.

Elevate your arm to full stretch above your head and the clubshaft will be perpendicular, or at right angles, to the vertical plane that your arm then rests on........and so on and so forth according to the orientation of your arm.

Are you sure about that that is what it is perpendicular to? I think RWH has it.

6-B-3-0-1 THE FLYING WEDGES The Clubhead may appear to move in a an arc around and outside the Hands when related to the Left Arm – the very basic Left Arm Flying Wedge. But when related to the Right Forearm, it appears to move “On Plane” with the Right Forearm, at its normal rigid angle (Bent Right Wrist) – the Right Forearm Flying Wedge. So – except in Sections 1 and 3 (Chapter 8 ) the entire Left Arm, the Clubshaft and the back of the Left Hand are ALWAYS positioned against the same flat plane – the Right Forearm and the Clubshaft are, in like manner, positioned on the plane of the Right Wrist Bend AT RIGHT ANGLES TO THE LEFT ARM PLANE. That is the precision assembly and alignment of the Power Package structure and is mandatory during the entire motion. Hitting or Swinging. Study 4-D-1 regarding “Grip” and “Flat Left Wrist”. Also see 7-3. Then, ideally, the Left Wrist is always Flat and the Right Wrist is always Level (4-A-1, 4-B-1).
