Pin axis layouts on asymmetrical equipment?
« on: March 17, 2008, 12:25:50 AM »
I don't plan on drilling a ball like this anytime soon but was curious if anyone drilled a asymmetrical ball with a pin axis layout?  How was the reaction?  

I always hear of bowlers using this layout on symmetrical bowling balls but don't think i've ever seen someone use it on a asymmetrical ball.

I havent drilled any with the pin on the axis, but I have done a couple with the pin 1-3" from the axis, 105* drill, MB in the track.  I love this reaction.  Decent length, very good midlane read, smooth but strong reaction, and very good continuation.  Lots of 9 pins if your not careful though.

Chitown,

Have you been to Jeff Carter's charity balls for sale sight?  I think he has a PDW Shift w/that drilling?  Is that what it is?  If not, what drill layout is that?  I'll provide a link:

You'll have to scroll down to about mid page.  It's the PDW tour used ball on the right.

PDW's ball is probably a "Pro CG" ball so the CG is in an odd spot...just a guess though.

No, the cg & mb are in line.  I don't see the pin anywhere, so my guess is that it's in the balance hole, drilled out.  That's why I'm asking if that is a pin axis drilling.

A perfect pin axis layout is designed to spin tight and have no flare. When you're using an asymmetric core, the core always wobbles, because it's lopsided/out of balance. Therefore, the pin will never stay perfectly on it's axis and spin tight. When the pin /core is wobbling, it's starts to spin slower, thus losing revs and gyroscopic energy.

This is why symmetrical cores are used for pin axis. When you nail the drilling, the pin never wobbles going down the lane, spinning perfectly tight and fast, like a spiral thrown football. This stores up the most energy, because the ball is spinning faster.

But, because of no flare, the ball needs more dry boards down the lane to react. When it's right, it's really right..!! =:^D

When a house bowler misses the mark, misses the break point and strike, for many ppl its called a wallshot. When a pro does that its call adjustment

When a house bowler gets his finger stuck in the ball and fall on the lanes, for many ppl its called lame bowler. When a pro does that its called the Machuga flop! ha i like this one.

Yes and no. It wont flare, but it will still hook at the backend. A pin-pap layout rolls so early it will almost not hook at all in the backend.

If you don't want the ball to flare, you can alos place the pin 6 3/4" from your PAP =:^D
