Question

bowling ball
Hello Warren,

Attached is a picture of the Flash force bowling ball my uncle gave me. I'm just wondering based on the pin position, what is supposed to be the backend and length reaction of the ball? can you please give me an idea on give this pin position setup, what the ball will ideally do?

Archie

thanks

Answer
Archie,
The position of the pin reflects the intent of the driller and can be determined by the bowler's Positive Axis Point (PAP). Can't really see the ball track in the picture, so there is no indication of your uncles track/PAP.

The pin placed below the fingers could be 6 inches from your PAP if you rolled the ball with little or no axis rotation (maybe a PAP of 6 and 1/4 inches over and 1/4 inch down). But, the same pin location on a ball rolled by a bowler with a PAP of 3 and 3/4 inches over and 7/8 inch up, would have the pin only 3 inches from your Positive Axis Point. So placement of the core when laying the ball out to be drilled (where you put the pin and center of gravity) should be dictated by the bowler that will use the ball and what kind of reaction you are trying to achieve. A 6 inch pin position will roll differently than a 3 inch pin position.

Do you know your PAP? Do you intend to roll it? Can your current driller determine your PAP (most basic info needed), your rev rate? axis tilt? axis rotation? ball speed? The more info the better.

Balls are terrific tools, but if you need to tighten a screw in your glasses (very small screw) and you had a regular size screw driver, even though your tool was similar to what you needed it might not be effective. Bowling balls are great tools, but they MUST fit what you need and provide the ball motion that is usable for optimum effect.

Thanks for the question. Please provide more info and we can better determine how you might utilize this ball.
