When someone refers to a ball layout that has a 2" pin buffer, where is that measured from, and how does the pin buffer distance affect ball reaction? Thanks.

Pin Buffer
The distance the pin is from the bowlers Perpendicular Axis Line or PAL (also called Vertical Axis Line - VAL).

from Storm's site, glossary, a fine place to start when you are wondering about something, just about every company has them.

Thanks azguy. I'll check out the Storm site. If you have time, how does the pin buffer affect the ball reaction?

Someone correct me if i'm wrong.. But if the pin buffer is the distance of the pin from the VAL, then i'm pretty sure that the closer the pin is to the VAL, the stronger it is down lane.

Again, correct me if i'm wrong.

I think it depends on the Pin-PAP distance first. If it's a 1" pin to PAP, I don't think it will be very strong down the lane. If it's a 5" pin to PAP, then it could be strong depending on other factors.

I think pin buffer is similar to pin height above the midline: After the pin to PAP is taken into consideration, and after the MB position on strong mass bias balls, THEN these 2 "buffers" help resolve the snappiness or slowness of the ball's reaction to friction. Lower pins are slower to react while higher pins are quicker to react (making many balls have a more skid/snap reaction).

While there have not been a lot of technical explanations about this, the above summarizes what I have gotten from past discussions of it. I could be wrong also, but these will remain my assumptions, until some knowledgable driller or tech person explains it better to me.

Read this and see if it explains better than I can type.

Roger,

That's the Storm "pin buffer" drilling instructions, vs Mo Pinel's dual angle drilling instructions. 2 ways of combining pin-PAP distance + PAP-pin-MB angle + pin height above the midline.

duvallite also wanted to know how it affects ball reaction.

I have never used a "pin buffer" in the layouts, so I can't help there. Just thought by posting what Mike Austin had done on his ball might help in some way. I used to have a better explanation for the pin buffers on a site, but lost most when my stupid computer decided to take a vacation a few weeks back.

Off topic, but am considering an Apple, I hear tell they don't crash as much and are a bit better in the hacker field, not sure on either case, still researching. I'll do some more digging on the pin Buffer to find a better explanation of reaction/location/length.

It's slow in the shop for a few more hours, anyway.

I found a couple ...look at these and see if that answers your question....

Pin buffer is a reverse way of measuring pin height. As the pin moves towards the VAL, if it stays the same distance from the PAP, the height of the pin above the midline (or, really, below, putting the pin below the midline is exceptionally rare) must increase. Further from the VAL, the lower the pin.

Specifying the pin-to-PAP and MB-to-PAP is not sufficient to establish the center of grip since you could rotate the ball around the PAP and vary the location of the grip. Specifying either the pin-to-midline, pin-to-VAL, or any of a variety of angles nails down where the grip center must be.

If you go here: http://www.rotogrip.com/products/balls/video/

And then click on Seminar.. Then watch Seminar12 (at the end) and Seminar13 videos, you'll see Pete Weber roll 3 balls..

The second and third ball has the same 5x5 layout but with different Pin Buffers..

You can clearly see the difference in reaction...

duvallite · « **Reply #12 on:** July 14, 2008, 01:33:17 PM »

Lillen,

those Rotogrip videos were very helpful and do a great job of showing the affect of pin buffer length. Coincidentally, since I am considering getting a Gravity Shift, watching Pete throw one with different pin buffers and seeing the difference in the ball reaction is just an added bonus for me.

duvallite - Thanks, I'm glad I could help...
