Pin / cg / pap

[eugene02]

How do I choose where should the pin be if i'm ordering online.. My pro shop which I made my balls did not tell me which is which and what is what.. He only sees the ball and ask his assistant to get another ball of the same type but different pin i guess... thats why i'm curious to know for future ordering online all this.. thanks :)

What is being referred to when ordering a ball online is Pin to CG distance.

For most normal layouts you want Pin to CG distance between about 3" to 5". this will give the driller "room to work with" when laying out the ball.

Look at the balls you have now, measure from the pin to the cg. That should give a good idea of the measurement for ordering.

[jaydee]

If a pin distance is too short (usually less than 2") or too long (more than 5") it is usually considered a "2nd quality" or "pro pin" ball because it limits your options as far as drilling for most bowlers and are less desirable. Typically most bowlers/drillers like working with a ball that has a 2-3" or 3-4" pin distance.

The yellow dot by the fingers is the Pin.

Finding the CG on a Lane 1 is a pain. There should be a little mark around the label.

looking at your pic. Look at the "N" in the word lane, there's a little dot "." in the "N" that should be it. (if not its close enough)

looks like maybe a 3"-4" Pin.

1 more question.. what is the top weight??

[bowl1820]

1 more question.. what is the top weight??

Top weight is extra weight that is added to the ball to compensate for the weight removed by drilling the finger holes. the top weight of a undrilled balls can vary. 2-3oz top weight, or 3-4oz top weight are pretty common.

If you have the org. boxes your other balls came in, just look on the label it should have it on there. That will give you a idea what range to get if they ask for a top weight.

Example:
A ball with a 3-4" pin and 2-3oz. of top weight. would work for most typical layouts.

if i want a medium 15lb ball.. how much weight one should i get?

whats the meaning of the PAP?

[bowl1820]

whats the meaning of the PAP?

P.A.P. means "Positive Axis Point" this is referring to the initial axis your ball is rotating around when you release the ball.

It is used in laying out a ball to predict how the ball will react.

what's CG? never noticed that thing before..

[bowl1820]

what's CG? never noticed that thing before..

Center of Gravity (CG)

The addition of the internal weight block will create an uneven distribution of weight in the ball. This imbalance will result in a portion of the ball being heavier. Identifying the heaviest portion of the ball is the first step in being able to effectively use this imbalance.
Center of Gravity (CG)
Since a portion of the ball is heavier than the rest, logic would dictate that gravity will pull the heaviest side of the ball down to the bottom of the ball. With the heaviest portion now located at the bottom of the ball – the ball is completely at rest. The axis running from the point touching the ground through the top of the ball is known as the center of gravity (CG). The whole mass of the bowling ball is concentrated around this axis.
An easy way of understanding the concept of CG is using a top as an example. A top is an unbalanced object with one part being heavier then the other. When putting the top into motion, it will eventually spin or rotate around a fixed or central axis. This point or axis (where the weight of the object is evenly distributed) is the CG.
Some ball manufacturers will determine and identify the CG on the ball by putting a punch mark into the ball. This mark is usually located somewhere within the label of the ball.

hmm wonder where the CG on my ball is..

[eugene02]

hmm wonder where the CG on my ball is..

post a pic of it here and see if we can find it for you.. posted mine and found it.. :)

[martin]

maybe later on sunday or monday..

[eugene02]

sure! anytime when your free to do so!

[bowl1820]

What ball is it? most companies put a symbol on it for the cg.

like storm has a little circle with a dot in it. Rotogrip has a little four pointed star.

mine is a lane 1 thn in the middle of the N there's a dot.

[bowl1820]

mine is a lane 1 thn in the middle of the N there's a dot.

Yeah like I said earlier.

[eugene02]

Yeah like I said earlier.

yup! thanks to this forum thread that i know how to order a ball from the internet if i were to ever get 1 !

mine is a Brunswick Anaconda

I believe you should see a small circle with a little dot in it.

see it here

too obvious to miss it anymore! hahaha

does drilling involve CG? what does it affect?

[eugene02]

does drilling involve CG? what does it affect?

yes it does. if you realize when you hold your ball, one side feels heavier. because the ball CG is not directly below but somewhere at the side.. if im right...

[bowl1820]

Now your into a complex and controversial subject that involves the USBC rules on static weights and modern balls.

Only thing for sure is that the CG matters in terms of keeping a bowling ball within the USBC guidelines for static weights after drilling.

There are two sides. "CG Matters" View and the "CG NOMADDAH" View

Oh... CG doesn't really mean anything if not for USBC rules.. hmm.. interesting! another thing learned! Thanks!!

[martin]

hmm i see.. btw, found my CG.. lol..
