Bowling Ball Pin Placement

In the ball rating matrix i rate the rg on a scale of 1 to 10 with the pin in the leverage position.

Bowling ball pin placement.

Even standard label drill patterns with the pin at 1 30 from the cg place the pin very near almost everyone s leverage point. The pin location has the biggest effect on the balls reaction and core location. Jason sets earl up to throw an undrilled ball down the lane several times adjusting its grip to accommodate pin placements of 3 4 and 5 inches. The layout of course defines how the core is oriented inside the ball relative to the bowler s pap and relative to the gripping holes.

Bowling ball manufacturers have to center the cores perfectly inside the ball and to do this they have to suspend the core in a stationary position while the mold hardens. The pin is a colored dot on the ball that signifies the position of the top of the core in the ball. In the drilling layout the pin placement how close or far the pin is in relationship to your positive axis point determines the ball reaction you will have. When a ball is built the core anchored by a small rod is suspended in a mold and the cover stock is poured into the mold.

Depending on the volume of the lane pattern and the friction of the lane surface you might need either a pin up ball or pin down ball to give you a good look on something longer. Pin to pap distance is one element of a bowling ball s layout. Often the pin rack is referred to as the pin deck although they re not synonymous. The pin deck is the area of the lane the pins rest on.

When the cover material. So if you had two identical bowling balls one with a 2 pin and one with a 4 pin and you put both pins in the same location then the only thing you have to worry about is the final destination of the cg and how much weight it carries. Your axis of rotation is the initial axis of the bowling ball as it first leaves your hand. We re often told two main things about how pin to pap distance affects ball motion.
