This may fall under cgnomaddah...but
« on: December 15, 2007, 04:32:22 PM »
Lets say you take a 2 symmetrical balls and drill both with a 4" pin to pap.

On one ball, you tune the cg out and place a weight hole bringing the ending sideweight to 1/2oz positive.

On the other ball, you tune the cg out so that you'd end with a 1/2oz positive side after drilling without a x hole.

Would we see any variance in reaction?

Sure would... but I highly doubt you'd notice a difference on a THS anyhow...

Strictly speaking, and to my understanding,  The physically marked location of the cg shouldn't make as much ( if any ) difference on the reaction of the ball as the placement, depth, and size of the weighthole needed to bring the first ball back to 1/2 oz side.


  While setting the first ball up, remember that, by adding holes, you are moving the ACTUAL location of the cg from the factory marked spot to the place it will be after drilling.  This is true on any ball.

  It is my understanding that, if you perform the exercise you have described above, that if you end up with two identical balls as far as static weights ( finger, thumb, top, bottom, and side ) that the two balls MUST have the exact same ENDING cg location, regardless of the x-hole used to achieve this.( this is to say that, if ALL factors END UP exactly the same, then the balls MUST be EXACTLY alike in regards to static conditions)  Then, the x-hole would become the control factor itself in regards to flare control.

 ( Upon editing, it appears that I need a proofreader more than a spellchecker, LOL!)

Who said anything about house shots?
 
Juggernaut, I guess removing weight from the core via and x hole would change the core dynamics.

Just the placment of the x hole would change the reaction slightly. see brunsnicks video about x hole locations

It all depends on:

A) the size of the extra hole
B) the depth of the extra hole

For instance, if you were to kick the cg out and still only had 1 oz. of positive side weight, the size and depth of the extra hole would not be large enough or deep enough to significantly affect the core dynamics. Thus not change ball reaction.

Conversely, if you were to kick the cg out to where you had 2 oz. + of positive side weight, you would have to use a fairly large (at least a 1" bit) and deep extra hole to remove enough weight to bring it to 1/2 oz. positive side. This hole would remove enough core material to significantly change the core dynamics and you would see some difference in reaction.

As stated previously, placement of the weight hole will also affect ball reaction.

One thing you may want to try, if possible, drill the 2 balls as you suggested, but don't put the extra hole in the one that has excessive side weight until you throw both balls side by side. I am confident you will notice no difference in reaction. Then place a weight hole in the one with excessive side weight and see what the difference's are.

Enjoy!!!!!
