To Static Weight experts!
« on: February 20, 2005, 02:12:16 PM »
A funny thought happened to me recently.

We think of static weights in relation to the grip.
YEs we must weigh in relation to the grip for getting a ball legal.

BUT, shouldn't we think of static weights in relation to the original ball track.

I mean a ball that has a static weight of 0 still has weight imbalance in relation to the ball track.

And if a guy is a low tracker he has considerable side weight if measured in relation to his low track.  Maybe this combined with not much surface like a high tracker touching the lane may have something to do with the low tracker difficulty in handling oil.  Though he may have a legal side weight in relation to the grip he may have 3 ounces of side weight if measured in relation to his first track.  Whereas the high tracker may be be legal and only exhibiting 1 1/2 ounces of side weight if measured in relation to his primary track.

I'm sure in the days of yore this was a concept thought of and discussed in the past.

Gurus?  T-God?

REgards,

PS along with this question are there many of you that have tried 6 X 6 drillings etc for length.  How much backend do you get?  Or 6 X 6 1/2?

And I don't have a knowledge of physics, even though i admitted that theoretically, there will be a difference between reaction, but in reality, it will not be more than a board difference, something we shouldn't rack our brains over?

OK if cg doesn't matter why don't you guys do the following.

Get two balls the same model and manufacturer drill both with 5 inch pin to paps.

One of you drill it stacked and the other put the cg out towards the negative PAP.

Good luck not seeing the difference.

Now if you guys don't mind.

Start this post.

"Why I believe CG doesn't matter"  There you guys can sit around and pat each other on the back.

the only probable difference from these two would be the effect of a weight hole  The layout with the cg towards the negative PAP doesn't require a weight hole.  The stacked layout will likely require (or at least capable of accepting w/ out being illegal) a weight hole.  Without the weight hole, both symmetric core balls (same pin to PAP will be very similar in reaction).  Using a weight hole changes that as it changes core dynamics.

LL, see what you've started. A great question, but now it is entirely over my head. My thought today with symetric cores the Cg was used to find the MB, and to tell the driller where the heavist portion of the ball(prior to drilling) is to determine whether the ball would need a balance hole?

Similar to yelling fire in a Movie theatre as it is to yell
"CG" at a Brunswick bowlers meeting!

REgards,

Luckylefty
PS If CGs don't matter how come you don't throw your 4 X 0 drilled ball fromt the inside unless the backends are screamin!
PPS Don't worry you can yell "CG" at a Storm meeting, Columbia meeting, Dynothane meeting, AMF meeting, Track meeting, Ebonite meeting and a Rotogrip meeting.  If fact if you yell cg at a Lane#1 meeting they may just get all excited and go out and buy some more coverstock from you know who..... Brunswick.
How do I know?  They put it on their drill sheets!
PPPS Still love ya Brunswick baby, in fact I had a good shot at 300 today with my Dynamic groove, drilled as though cg didn't matter!  3/4 of side weight baby on everything, special sauce included!

Because generally speaking, a 4 x 0 or 0* layout requires a huge and/or deep hole to make the ball legal. It's also generally placed on the axis.  This gets the ball to start up very quickly and expend energy throughout the entire lane.

I've had a 4 x 0 that had very low top to start out with so the weight hole was very small.  That ball cornered much harder than others with the same layout and I could play anywhere on the lane with it.
