Plastic Ball
« on: February 22, 2009, 04:30:29 AM »
The PBA Plastic Ball ball is supposed to be a pancake block core.
How was Weber and Carter getting 1-3 inches of track flare with noticable flares from a pancake block?
My plastic ball has a .75"-1.0" track but exhibits no flare.

Reduced Speed + Rev Rate + Rotation + Strategically Placed Weight Holes = Flare.

500 grit anything is going to flare with the leverage these guys create.

Also there isn't much oil out there, around 30units, reactives would have hooked clean off the lane.

I'm not really sure exactly how to do it, but back in the day I had a wine colored white dot with higher topweight drilled with a finger positive label shift ( much like Jeff's was today ) that would flare.

  That ball was special too. It seemed to carry better than other white dots I  had seen.  We always thought the fact that there were multiple oil rings on it was strange, but we didn't know much back then, so we didn't know what they were or why it did it.

  Shot an 800 series with it one day in practice and won MANY pot games with it after league was over.

 I miss those days

 P.S. Did anyone notice that when they showed the cutaway balls that it showed the pancakes in these balls to be on the bottom instead of the top?  I wonder if that was just a mistake or if it was for real?

Are you saying that CG mattered?!?!?!

On balls without cores they absolutely matter.

I know you're being sarcastic, but  ...
On pancake cores, covers, surfaces and CG position are the three that matter most, after the oil, lane and bowler's release. Static weights matter a whole lot on "pancake cored" balls.

I'd bet Jeff Carter had a leveraged CG posiiton, with a weight hole on or past his axis point to add to the flare and hook potential. Besides all balls were dead dull: 500 grit or rougher.

The cutaway was like that because thats how the block and filler is held in place when the shell is poured. The "pin" on most all 3 piece plastics are actually on the bottom of the ball. The block is still under the label.

"Hand", as it's been referred to in this thread, or higher revrate, creates more flare potential than a weaker release would.  In college I bowled with a teammate whose revrate was in the high 480-500 range with alot of end over end roll.  He went though many plastics looking for something that would go straighter with his A-release because the White Dots and Target Zones he was drilling up *RIGHT OVER THE LABEL* were flaring 2-2 1/2".  The Viz A Ball seemed to be the best fit for him as it flared maybe 1/4" at most.  

You guys also have to consider that the differential on a pancake core is still in the 0.16-.020 range depending on density.  It's very easy for a high RPM player throwing with a softer speed, which enables the ball to migrate even more flare, to get 2" or so of flare out of that ball.  Whereas a women's series player with a 180-225 rev rate would see 1/4"-1/2" of flare out of the same spareball.

Pancake weight blocks do not flare.  These blocks do not create any wobble at all.  With this type of weight block your track will be higher and thats what you saw on todays show.  The track was about 1/2 to 1 inch wide due to the hand position change for some of the spares they shot.  Thats it.  Back in the 60 and 70's, bowlers had a lot of pride if their track was very narrow.  IT showed that they were releasing the ball the same way every time.

Wrong as can be.  Some exempt pros last week were getting 2-3" of flare out of their plastics as noted by Storm rep Chris Schlemer.  I've drilled hundreds of "pancake blocks" that can and do flare.  Not very much, but any migration or separation of initial track lines shows flare separation.  You can clearly see on the show that Pete had about 4 or 5 tightly spaced flare rings on his dull ball.  I have a Black/Red new model Scout reactive from columbia with just the pancake core at the top that has 2" of flare ring separation, and an 80s red pearl white dot that flares about 1 1/2".  Would you like pictured evidence?

I believe Chris Barnes mentioned he went with a leverage drilling. Carter's CG looked way right as well so I'm sure he went with something similar.
