Endless Belt Effect

Endless Belt Effect- The change of the clubhead from Linear Motion to Angular Motion.

The clubhead and Belt (hands) travel at exactly the same speed; however there are two (2) different surface

speeds between the pulley and the clubhead.

The Belt (hands) speed never changes but the clubhead speed increases as it goes around the pulley.

The hands act as the belt they must not speed up, slow down, or become jerky.

The hands do not change speed during the release. The smaller the pulley the slower you can swing.

The later the delay the slower the hand speed. The faster you swing the harder it is to keep the club from flying out.

Imagine a golf club on a Belt as pictured below. As the club reaches the pulley the hands continue around at the same speed but he clubhead speed increases as it goes around the pulley.

The larger the pulley the slower the clubhead speed.

The hands represent the Belt. The club is attached to the Belt. When the Belt starts to curve, that's when Release starts.

It is the same when we go to the show and watch the ducks go along on a pulley as we fire an air rifle to knowk down the ducks so we can win a prize.

As the ducks reach the end of the belt they go around a small pulley and then gradually come back on the other side of the belt.

This is exactly the same priciple.

So with a Circle Delivery Path, there is no straight line portion in the Endless Belt.

With a Snap Release, there would be a larger straight line portion, with a sharp turn as it reaches the curved part of the Belt.

The clubhead speeds up instantaneously as is reaches the curved portion of the Belt. During the linear or straight portion, the clubhead travels at the same speed as the Belt.

Remember, the Endless Belt Effect is only one concept. It should not be considered on its own. For example, during Release there is extension of the Lever

Assembly, which, via Conservation of Angular Momentum, means the Belt has to slow down (since more mass gets further away from the centre).

The pulley is actually the Release point in the downswing. The smaller the pulley the faster the clubhead speed (Centrifugal Acceleration).
