PAP Question
« on: August 24, 2012, 10:06:56 AM »
I have a PAP question here....

When checking the wear of my ball's track, if I measure my PAP using the top of the track wear, it measures 4 1/4 x 1/2 up.

Just before I was forced to quit bowling approx 2 1/2 mos. ago, I Bought a new ball and the pro shop had me throw one of my balls to check the PAP and the driller said my PAP is 4 7/8 x 1/4 up.

Is it possible for the "real" PAP to be different than the top of the wear track the ball shows per the nos. I show above?

...  But Mo Pinel is the expert on modern layout technology and he says to ignore any flare before the ball hits the lane and use the PAP based on the first oil ring...  --  JohnP

Thank you. My point exactly.  Who cares whether the ball is getting ready to flare (precessing) if it cannot be used in a practical way?

Then based on what Mo Pinel says, then the first oil ring on my ball which is also at the top of track wear, would be the correct PAP on my ball which is 4 1/4 x 1/2 up and not the 4 7/8 x 1/4 up the driller said it is after watching me throw 3 balls., is this correct?

Just what do you mean by "the top of track wear"?

To locate the the PAP you use the first oil ring closest to the gripping holes, then then measure that location from the grip center.

It's best to use an oil ring.  If you get your PAP off the track on the ball you have to remember that the top ring by the fingers/thumb will go through the bowtie and become the bottom ring on the far side of the flare.  When you use one single oil ring that becomes obvious.  If you have trouble seeing the rings sand the ball down to 1000 grit and then throw it.  The rings should be obvious.  --  JohnP

Thanks John. I think I now understand.

To get the truest PAP possibly you need to throw a ball with minimal to no differential. (AKA plastic with a pancake core). There will be minimal to no flare before the ball hits the lane and there will only be one oil ring to evaluate. Granted the only hitch is you need to throw your plastic ball with your normal release and not flatten out.
