When is a Brunswick ball a blem? --- Top weight question
« on: July 27, 2006, 08:07:24 PM »
Just a question about Brunswick production... can anyone tell me which production tolernace Brunswick allows for a ball? I recently got a used PG Dry/R (Pin distance was 3 1/2"), 1st drill already plugged, and it turned out to have incredibly high top weight - on a dodo scale it was far above 4 ounces. My driller was puzzled, he'd never had a ball like this before. The finger holes had to be drilled 4" deep each, plus a 1" wide x-hole 3 1/2" deep (all the holes meet in the ball's center now, no vent holes needed at all!) to get the ball hardly legal with all the material taken out. I haven't played it yet, but I wonder if it will do fine?

What could be the reason for this weird and high top weight? On the scale, most of the extra weight must have been placed close to the pin and shifted towards the positive ball's side. Could one of the PG's DISC pucks have got lost and moved towards the pins?
I'd also like to know which maximum specs of top weight come into public sales, or, alternatively, at which point does a Brunswick ball becomes a "blem"?

Any idea or insights from a half-official party would be fine, thanks in advance.

Do you have real small fingers?  I have a Triple Threat that had 4oz of TW (at least that's what the box said) and I didn't have the fingers or thumb drilled especially deep.

Well, I have slender fingers, but I would not consider them small. No, the ball had such a weird and high top weight, it even shocked my driller who is a Brunswick staffer. Only thing I know from the previous owner is the "the ball did not roll well" - but he used it on short oil with a label leverage drilling, and I blamed it on that not really suitable drilling. But with this huge top/side weight, it is ovious why the ball did not work... hope it does a decent job now?

My crash had over 4oz top weight, but I have large fingers. No problem getting it into spec.

Grips?  Remember, if you use inserts, then your finger holes are as large as everyone else's.  If not, then if your fingers are 25% smaller than mine, your holes will be just over half the size of mine, in terms of weight removed because the volume of the hole decreases with the square of the size of the bit, not linearly.

That's one possibility.  I'm not saying that's why, but removing 4oz of TW shouldn't require drilling four holes 4" deep.

No, we did not have a DeTerminator at hand - but after 1st test on Friday I'd like to know what is going on inside of this particular ball!

Despite the deep holes and the x-hole and its CG at about 75° from PAP, the Dry/R has 3" of negative flare across the thumb hole, touches the middle finger and almost reaches the x-hole!
I have the impression that the ball skids all the way down (hard to tell because of the color. will use some tape next time).

I was able to play it down 10th board into the pocket (does a wide, smooth arc), but it does not finish well, almost splattering pins like a polyester. I guess the negative flare prevents the ball from rolling or having a back end reaction at all.

I think this case is completely for the dust bin... Uh, what a waste of money and time... Nevertheless, I like the Dry/R's reaction. I might try to get a "better" or a new one to fill my arsenal gap for fall.

There is something to this theory... because my Dry/R totally mis-behaves against its drilling. Good advice, though, but I an not sure if my pro shop has a DeTerminator at all. We even had problems with the ball on the dodo-scale because of thw acky weight distribution, and obviously there must be something more wrong than just excessive top weight... I even thought about sawing the ball open, just to see what and where things are inside?

Funny you should mention Power Grooves and weird flare...

I just drilled a Teal/Purple with a 2 1/2" pin-to-CG distance, using the 4E layout from the drill sheet.  I don't remember the exact ending statics, but they're well within USBC regulations.  I have a pretty average track, with a PAP of 5 3/8 over and 3/16 up.

Well, the first oil ring on this ball is between the thumb and fingers, and it flares *backwards,* with the last flare clipping the edge of my thumb insert.  However, it reacts almost exactly the way I'd expect something with this drilling to react--clean in front, and even transition at the break.

Odd.
