Hello Group
Could someone explain to me what "pin buffer" means? I see it all of the time when I see people explain how that have their set up,
Like for instance: 5x5 with a 3" pin buffer. So whats the advantage of having something like that or do all balls have that?
Thanks

Distance the pin is from the bowlers vertical axis line is how Pin Buffer is defined.

Here are some drill sheets by Storm that talk about Pin Buffer

Morich also talks about how pin buffer distances can effect down lane movement (reaction shape/speed)

Pin buffer basically determines how fast the ball reacts to friction down lane.

Most often if the pin buffer is dramatically less than the pin to pap measurement. Then the pin is UP.
ie pin to pap is 5 1/2 and pin buffer = 2 inches then the pin is up quite a bit!

Three dimensions are required to define a layout. The first and most important is the pin to PAP distance. The second specifies cg or mb position and can be either the distance from the PAP, or the mb to pin to PAP angle (usually, but can also be cg to pin to PAP). At this point the pin can be placed anywhere on an arc around the PAP that satisfies these two dimensions. The third dimension (that exactly determines the pin location) can be pin height above the midline, pin distance from the vertical axis line (pin buffer), or a second angle to go with the mb to pin to PAP angle (see Mo's dual angle layout technique). -- JohnP
