What is the endless belt effect?
What are the component variables involved?

What is longitudinal acceleration?

I’ll start with the easier one.

Longitudinal acceleration is the pull on the shaft in a straight line used by swingers. From the top of the stroke the shaft is pulled by the hands pulling the grip or by pp2 pulling it in a straight line grip end to aiming point or adjusted hands. . Shaft is parallel to plane line. Simply- pull the grip down in a straight line past your front leg.

So how does the clubhead hit the ball with the hands so far in front?

With the concept of the Endless Belt.


Lets see: Homer came up with the name endless belt from the old arcade game of shooting ducks. They were on a belt that allowed them to be shot and rotated back in line to be shot again on the loop of the belt. Like the old ride ‘The Whip,’ the ducks noticeably picked up speed as that went around the top belt line to the bottom belt line, although the belt speed remained consent.

A constant speed (by the hand holding club) produced an increase in speed as the clubhead “switched ends” with the grip. Just like the duck, the clubhead increased its speed because it had a longer way to travel as it when from linear path ( longitudinal ) to an arc path. Who says physics does work?? This same principal produces lift on an airplane wing as the top air needs to speed up the travel a longer distance of the wing’s foil.

So what happens? You now know that it is ill fated to try and speed up the hands top produce clubhead speed. Sustain the Lag and keep the rhythm of the stroke intact. AND gain a ton of clubhead speed thanks to the laws of Nature.

As Lynn wrote: The Endless Belt Effect (2-K) describes the increase in clubhead Surface
Speed with no increase in Hand Speed (Belt Speed) during release. The Effect is the same for both Hitters and Swingers and is exaggerated with Snap Release (10-24-D/E) and a Line Delivery Path (10-23-A/B/C/D) and minimize with a Sweep Release (10-24-A/B/C) and a Circle Path (10-23-E).


Hope some of that helps.
Big pulley to a smaller pully with a gain in suface speed without an increase in the belt or hand speed. Trust the force.
