Brunswick's flare increasing/decreasing diagram
« on: January 18, 2004, 10:03:20 PM »
Does anyone have a copy that they could e-mail me?  I need to refer to it today if possible!

Never mind!  I called Tom at Brunswick to ask him to e-mail a copy to me and although he did e-mail it, he also told me that the diagram is included in the drilling instructions!  I almost never look at those anymore!  Sorry about that!

There's a section in this page about using an x hole to increase/decrease flare

Hope it's what you were looking for.

I couldn't disagree more with some of the comments regarding weighthole position in this drill sheet referenced above!  

A weighthole closer to the grip center will decrease flare and make ball go longer!?  NOt the weightholes I've drilled in that area.

Anyway.  I have posted a long winded post on this section.  Where to go for drilling info.  Upcoming in the next couple of sections is one on weightholes.

Oh, here it comes.  WHo am I?

Really nobody.  Just a guy who's put over 300 weightholes in about 60 balls over the last 5 months.  Mostly just nutty!  But I did catalog the results and changes in reactions as I saw them.  

REgards,

PS What I do agree with is that weightholes past the pap increase reaction, and weightholes on the pap and even inside the pap decrease reaction.  I am not in agreement with the theory that track flare is causing this increase in reaction.
PPS As reference to believe the experiment done in the following way.
Place a pin on pap drilling on a ball and place cg back towards grip center.
Say a 3 inch pin out ball.  Drill a weighthole on pap.  Very little track flare, and very little backend reaction.

NOw plug hole.  redrill weighthole like brunswick says, 2 1/4 inch past pap on a line from ring finger thru pap.  NOw one will see a dramatic increase in backend reaction with no or neglible increase in track flare!
Note track flare can be increased with large weightholes!  However many weightholes which are smaller do not effect track flare but DO effect reaction.

I've seen these explanations on weightholes at the Ebonite site.  It does account for some of stability on drilling weighthole on pin.


Majority of weightholes that I drill are not into pin and do not touch core.

Most only remove 1/2 ounce of sideweight or less.  Now how do we explain reaction changes if not nicking core.

Note I am not denying that changing core shape changes reaction.  I am just asking is it possible that this theory of weighthole effect does not cover all cases?

REgards,

Let's redo my example above and drill a ball with pin about 1/2 inch from pap and redo example.  First weighthole on pap, 2nd weighthole 2 1/4 past pap. The effect will be the same.  Neglible increase in track flare.  No altering of core and an increase in reaction with the 2nd weighthole.

Now in all reality I don't really care what causes increases or decreases in reaction (except for a mental exercise).  I'm only interested in where to I put a hole to change reaction in a certain way.  To me that is the practical application.  THAT I do know.
