core power
« on: November 17, 2008, 10:52:10 PM »
The cover material and how it is prepared is the primary factor affecting ball motion.  That being a given....

What do we expect and what do we get from the balls' core?

1.  We get - Flare - based on pin position and differential.
2.  We get - Hook shape - based on core shape and final Mass Bias position.
3.  We get - Wobble - based on core shape - to increase ball action in the pins.

What else do we expect and get from core design??

Sales!  Throw in a core that is "innovative" or "proven" and watch us chumps snatch 'em up.

That's an interesting aspect I never heard of...

Besides, the core determines how quick it can migrate towards its final end roll axis, and how well it stores energy (or depletes it). That's all. The amount of flare is determined by the drilling setup (while the RG. diff. tells you about the ball's flare potential, but that's something else or comes into play before a ball is drilled), and the RG value tells you how easily the ball revs up. Paired with the coverstock and many other factors you get the ball's reaction.

If it wobbles, there must be something wrong... really curious about this concept

Wobble was the term many people applied to the visual action of the first balls with core that cretaed siginificant flare. The ball appeared to "wobble" as it sought its primary axis and a stable axis.

In fact, as far as I know, you do NOT want a ball to wobble as it hits the pocket. You want to ball to be in the hook out phase, just beofre it goes into roll out. If it's wobbling as it hits the pocket, you just never know what's goign to happen. The effect may not be bad, but it may not be good either. It's just unknown how well or strongly it will hit the pins.

Good points.  Lil off topic......riggs is one of the best I've seen in person at roll out about a foot before the 1-3.  When he is able to do this his carry potential is tremendous.

Wobble is of course invisible to the eye - I did see a video of a clear plastic ball with a real core that was used to show the movement of the core and the wobble that was created by the core.  I think every weight block creates a roll with some degree of wobble - and I think that there is an optimum amount of wobble that increases carry percentage.  There is so much I don't know about core design and ball motion - I can't pretend to be the fount of knowledge here....  I wonder if asymmetric cores ever truly roll out?

Ah "wobble" I remember hearing that term used back in the early 90's.

It was applied to one of the first Asymmetrical balls, the Brunswick Phantom.

SEE HERE

At the time They knew it was good ball, but nobody seemed to make it work right or know how to drill it to get to work.

I wondered once how the ball would be now, using today's knowledge of drilling
asymmetrical balls and how to use them. how'd it be.
