Can a Golfer change the Size of the "Endless Belt Effect" Pulley?

Homer Kelley would say ABSOLUTELY . . .

2-K 7th Edition . . .

Another very important element in the generation of Angular Motion is the Endless Belt Effect (Sketch 2-K #6) which is the Physics of the Delivery Paths (7-23). During the straight line portion of the motion (Line Delivery Path) Linear Motion give the Belt and the Clubhead identical MPH speed. When the Belt starts around the Pulley (Release) its MPH does not change (Constant Hand Speed) but the Clubhead goes into an Angular Motion and its Surface Speed becomes proportional to: 1). its Radius, 2). Belt Speed and 3). Pulley diameter. Increasing the diameter and/or the Belt Speed increases Clubhead MPH and vice versa. The Circle Delivery Path is just one big Pulley - no Belt, no Linear Motion and therefore constant Hand Speed and Clubhead Speed (RPM) but different MPH due to different Surface Speeds. It must all comply with 7-23 - which is the Geometry of the Endless Belt Action.

AND PER 6-E-2 . . . You can change the diameter by simply chaning your Aiming Point . . .

difference in travel distance per degree of Angular Motion because Impact always occurs during the "Pulley" portion of the Endless Belt travel (sketch 2-K #6) regardless of the direction of its Straight Line travel between pulleys (or of the Thrust during the Circle Path per 7-23) because both of those lines represent the True Delivery Paths and move - physically - directly at the point on the Ball through which the Angle of Approach passes even with Aiming Point procedures because The Machine delivers the #3 Pressure Point to Impact Fix Hand Location AT IMPACT with all Delivery Paths, Delivery Lines, Pulley Sizes, etc. because its structure is designed to do just that, hence the importance of a sturdy structure around the Endless Belt machinery. That is what makes the Aiming Point procedure possible at all
