Bowling Ball Pin Position

A majority of bowlers don t realize how important it is and how much more the ball reaction can be fine tuned when drilling an asymmetrical ball.

Bowling ball pin position.

By changing the drilling location i e. Pin to pap distance is one element of a bowling ball s layout. To break it down in simple terms. Pin down the ball motion can be tweaked.

Watch the trajectories of two identical bowling. 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 preferred spin axis psa on an asymmetrical ball is one of the most misunderstood topics surrounding bowling ball technology in today s game. 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.

This is the most popular pin placement for the average bowler. Other factors must be considered. We re often told two main things about how pin to pap distance affects ball motion. Mass bias is created by using weight blocks or protrusions to create an asymmetric design.

Pin placement in drilling a bowling ball is not necessarily significant. The higher the rev rate the more impact the core can have on the overall ball motion. The position of the core stays in relatively. 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.

Mass bias is another way that the ball reaction can be tweaked. In the ball rating matrix i rate the rg on a scale of 1 to 10 with the pin in the leverage position. Sign up for virtual lessons by clicking here.
