Strong Asymmetrical Balls
« on: March 16, 2004, 01:55:48 PM »
Hello everybody,

I'm writing this to hopefully help explain why we're seeing the different replies in regards to some of the Track ball reactions.  I've heard replies ranging from "It hooks off the lane" to "My ball doesn't hook".  If we pay attention to the drill patterns that are mentioned for each person stating what they see, we should see somewhat of a consistent pattern in regards to their reaction.

Guidelines:

A Pin out or above fingers will produce quite a bit of length, don't do this if you want the ball to hook early or want to use it on true heavy oil unless you have a lot of turn.  Make sure you keep the pin under fingers for an earlier reaction.

The Mass Bias, also VERY important in the stronger asymmetrical balls.  For those who say your ball is not hooking enough, I'm hearing that the mb's are being placed in too weak a position for the ball to get into a roll. i.e., left of thumb, below thumb, or slightly right of thumb, these are also weak placements for your mb.  You have to place them towards val, on val or past val to allow the ball to stand up quicker in heavy oil or simply for the ball to get into a good roll to finish.  

I'm including a quote from Omega Bowler who has two Unleashes drilled differently. (See Thread:Unleashed Revisited...Omega Bowler)

 
quote:
The first one was drilled 4.5 x 5.75mb. 2” above midline
the second ball 4 x 4.5mb 3” above midline.


 
quote:
Unleashed #1 never turned the corner. Had it 1000 grit then tried it polished. It really suited broken down lanes where there was more friction and it could turn over.

Unleashed #2 Turns the corner big time. Revs up nice and faces the pocket very well. That was in Box condition.


Omega's main difference to me here is his mass bias, the mb plays a huge part of the ball's reaction in total.  Please becareful when laying out your new Track ball, I hope some of this info helps.

nice post Rick,

However, isn't the mb location to the right of the thumb "usually" the strong position, meaning most angular ?  Although not the best position for TRUE heavy stuff, ...still a strong mb for angular reaction, strong break-point shape, correct ?

king,
2 things.......
1. what the hell are you doing at home.......(I"ll be there about 1045!)
2. I don't understand ? It's down below my thumb, 2 inches right....

I'm saying that right of thumb USUALLY produces angular breakpoint shapes, yes?
Not necessarily good for heavy oil, but angular nonetheless....

part of my post was to say that a 1/2 if difference in MB will matter a lot with these balls.

ie: pin in same spot but MB at 4.5" = angular. 4 may give a hook set and 5 will go long.

In a lot of weak MB balls, the difference will not be pronounce as much and will require a completely different pin/mb placement to get a noticeable reaction.

CG/MB Location in Symmetrical balls will not matter that much at all and the Pin makes all the difference.

will it matter yeas. the hook shape and Breakpoint of these ball will change, But I belive only a little.

BUt the strong MB balls matter a lot. so they really make a noticeable change in ball reactions and in my mind that means they need more consideration when drilling.

the con side is that maybe that the expected reaction will not happed because of pap measurement being off.

that leads me to think that maybe PAP needs to be measured before drilling one because it may have changed and that will make you very disappointed.

tracks drill sheet specifically say that the #2 position may be sensitive to high rotation bowlers. try the MB on or past val. #3

remember the Unleashed is a light load particle that is Flip in Nature.

you have to manage the friction for this ball to work. this ball is best suited to manage the back end part of the lane. trying make this ball  a midlane ball is not the best choice.

If you redrill it for oil. place the pin 4" from pap and 1" above midline and the MB 2.5 from val to 1 past. wet sand to 600.

with your current layout. polish it and use it on med to med-light. you will like it for that setup.

Great thread Rick!!!!

Just to add one thing, and this could be the case with nicholskid87, when I attended the clinic that Del Warren and Mo Pinel have been holding across the country, they each specifically stated that keeping the PIN below ther fingers definately takes better advantage of what the ball's core will offer. SO, unless my customer actually wants one of these for medium conditions or for tremendous length I try to keep the pin below an imaginary line that splits the ring finger in half.

To answer Mr Revs, it is definately my experience that placing the MB anywhere from 3/4-1 inch right of the thumb or left of that point are fairly weak. Not weak meaning little hook but weak for an oil drilling. You are correct in that it creates a very angular backend, but with nowhere near the length that you get with the MB in the track.

Great post!  Although I haven't experimented much with minor MB changes (like .5 to 1") to see how much difference they make, the difference between weaker MB placements and on or below the VAL is drastic.   Putting the MB on or below the MB gets the core to read so much better and is so much stronger throughout the lane which is beneficial for oilier patterns.  If you want to weaken the ball, just place the pin further from your axis.

The problem I see with having the MB in the strong position is the tendency for over/under.  The ball wants to change direction so quickly when it encounters friction it's often hard to read.  However, if it doesn't encounter friction, it has a tendency to want to squirt too much.
