John, honestly, I think you can have it both ways. CF should square a Clubhead attached to a rope if the center of gravity and face plate are so designed/oriented, and it should be.
Left Arm as "Rope Handle", although Homer never suggested that the Left Arm is a Rope, I, personally, like to think of it that way with almost every swing.
Specifically, the Passive Release of the #2 Accumulator is the Swingers "Rope Handle" Application, while the Active Release of Accumulator #2 is the Hitters Axe Handle Application.
Quote:
Again – any time Accumulators #2 and #3 (the Hands) are employed, but only Pressure Points #1 and/or #4 (the Arms) are used to actuate the Primary Lever Assembly, so that Centrifugal Force alone actuates the Secondary Lever Assembly, this would be the classic golf “Swing” and the Clubshaft would exhibit to the “Rope Handle” characteristics mentioned in 2-K and 10-19. Study 6-C-0.
In this regard, "Rope Handle" means Rising Clubhead Pull. Axe Handle would be steady pushing against Clubhead inertia.
Homers string on a clubhead experiment demonstrated pure CF induced Horizontal Hinging.
Another way of looking at Pure Swinging is that it is non "manipulated". That is to say that the Hands do not manipulate the face in any way manner Hinge Action or otherwise. Your hands can not manipulate the face if the shaft is a piece of string. In his demonstration the string was the shaft! It ran from the head to Homers hands in the photo Lynn took. Indeed as Lynn pointed out the clubhead's sweetspot aligned to Homer's #3 Pressure Point given the string/shaft but thats another story.......
(as a further aside, it is possible to swing with just your left arm attached to the club and not be Pure Swinging. You can manipulate a hinge action with just your left hand on the club after all. In fact its easier to do with just your left hand on the club I find, way easier)
