RG And Differrential

RG Differential and RG What Does This Mean?

I will try to address this simply and with as little confusion as possible. I first must tell you I am not a scientist or a ball designer. I am always learning as are you. I am sure some of you have wondered what does some of the numbers on a bowling ball technical sheet mean and how does it affect me, the bowler. Why do I need to know it anyway. First I must address cover stocks and cores. The cover stock is like the tires on a car and the core is like the engine. These two things are what influence the bowling ball motion. You choose a bowling ball to match your style and the lane conditions you bowl on. Because of so many different style bowlers and bowling lane conditions, the ball companies make different types of balls, and are trying to make a ball that will sell. So that is why you see these numbers on a balls specs. sheet. Also, the USBC rates them to have a tolerance.

RG-
RG means Radius Of Gyration. The RG of a bowling ball tells you how soon the core is designed to roll. The lower the RG, the sooner the ball is designed to roll. The lowest allowed by the USBC is 2.43 the highest is RG 2.80. (USBC could change the rule anytime).

The RG Differential (also called just DIFFERENTIAL) -
This indicates the difference between the low RG and the high RG. The Differential indicates the potential for track flare which can be translated into hook potential. The higher the differential, the more hook potential the core possesses. The RG differential indicates the difference between the low RG and the high RG. The maximum differential allowed by the USBC is 0.060.Don’t get this confused with intermediate differential because that is different. This is used in asymmetrical bowling balls to measure the spin time of the bowling ball before drilling.
Note: All numbers on the spec. sheets are before drilling and that is an important factor as the numbers then change.
Ok this is what RG Differential and RG mean. But, the biggest influence in bowling ball motion is the surface of the ball and the force and direction of the bowler’s release. In addition, the condition of the bowling lane must also be taken into consideration...

Now here is a pretty good rule.

A lower RG ball with a low differential will produce an earlier rolling ball with a small arcing motion.
A lower RG ball with a high differential will produce an earlier rolling ball with a larger/stronger arcing motion.
A higher RG ball with a low differential will produce a later rolling ball with an angular backend motion.
A higher RG ball with a high differential will produce a later rolling ball with a strong, somewhat angular backend motion.

On differential:
The lower the differential the closer together the track flare. The higher the differential the further apart the track flare.The cover stock friction on the lane allows this to come together. Coverstock adjustment is needed to adjust to the conditions you are bowling on.Well I hope this helps and does not confuse you too much.

Good Luck and Good Bowling

Motion Of The Bowling Ball

The study of bowling ball motion are something that most bowlers know nothing about. In brief, there are three basic stages, or zones, a bowling ball must go through. These stages give the ball the proper reaction on a bowling lane. This has been the principal in bowling for the thirty years I’ve been in the game. Most bowlers don’t realize that a bowling ball goes through these stages.The bowling ball motion are as follows:


1. Slide – A bowling ball will first slide for a certain length of a bowling lane after it is released by the bowler. This is known as the head portion of the lane.
2. Hook – After the slide zone of the ball motion it will then transition into a hook zone.
3. Roll – Following the hook zone a ball will go into a roll stage. 
In summary – The stages of bowling ball motion are slide, hook, and roll.
You could Picture this like a rocket taking off from the earth to the outer space.

1. You must have a take off part so the rocket can get off the ground. = The slide.

2. After the rocket is off the ground it must transition to get out of the atmosphere. = The transition and hook.

3. Then transition again to adjust to the outer space itself. = The roll.

This is the same kind of concept involved in the study of bowling ball motion. 
Which is also true in bowling lane conditioning. The bowling lane conditions and the bowling ball motion must match for the best reaction.

If a ball slides, hooks, or rolls too early you will get roll out. If roll out is too early the ball stops and goes straight. If a ball slides, hooks, or rolls too late it will never grab the lane and could skid out. A bowler should study a ball rolling down the lane and realize that these stages happen. The study of Bowling ball motion is essential.

Different Types of Bowling Balls

The Different Types of Bowling Balls 
 
 
Here are some of the different types of bowling ball cover-stocks and cores to date. First there are 5 types of cover-stocks that I am going to talk about they are plastic,
reactive pearl, reactive solid, reactive hybrid, and particle.

There are 3 main types of cores in a bowling ball which include 3 piece, 2 piece symmetrical, and asymmetrical. Now in more out lined detail
listed below.

Cover-stocks 

1. Plastic - is usually used in 3-piece cores.  It does not have much traction on the lane and is lower in price.  It is mainly used as a spare ball or a beginner ball.

2. Reactive Pearl - is used in all types or cores.  Normally it has more of a skid snap reaction.

3. Reactive Solid - is used in all types of cores.  It has an earlier and smoother reaction than the pearl.

4. Hybrid Reactive - is mainly used in 2-piece symmetrical and asymmetrical cores.  This type of cover is made to give the bowler the best of both worlds as it has a combination solid reactive and pearl reactive.  It is mainly used on over and under bowling lane conditions.

5. Particles - This was a cover-stock that was made to combat heavy oil.  It had pieces, or particles, in the reactive cover to help it grab the lane surface.  There are not many companies making particles anymore, but there are a few. It was mainly used In 2-piece symmetrical and asymmetrical cores.


Note: Urethane Cover-stocks that were popular in the 1980's are now making a comeback.  They are not as aggressive as reactive bowling balls and are more powerful than plastic.  In addition, they are usually smoother in transitioning but do not have the hitting power of the reactive balls.

Bowling Leagues



Form your own bowling league!




Company League, Neighborhood Leagues or Just a Group of Friends
Lots of groups are now forming their own bowling league-why not you? In the past we have provided many different league opportunities to you-but we forgot to ask what you wanted, shame on us! Here’s your chance to do it your way.
You form a league of your own with friends, family, co workers or members of an organization that you’re a member of. You decide the time of day, day of week, number of sessions that you want to bowl. Then tell us how often you want to bowl weekly, bi-weekly or once a month. We’ll just provide the lanes for you.
Finally you will have a league you can enjoy with all the benefits you want including a great social activity and a FUN time with friends. Because this is your league you tell us the rules and how much time you want to spend with us.
Leagues can be formed with as few as 8 bowlers (4 Teams of 2). An extra benefit of bowling in a league with only a couple bowlers on each team sessions can be limited to 90 minutes or less too – no longer do you need to mark the entire night/day off your schedule.

For more information please contact Bowl-A-Roll Lanes at 585-427-7250 or email us at bowlarol@rochester.rr.com.  

Spring Leagues Now Forming












Where Good Friends, Great Times And All Around Fun Come Together 

It’s where you make friends. It’s where you break records. It’s where you reconnect with old pals and create new memories.  Join a league today to earn and get great deals on bowling, dining, and so much more. Your
lane is waiting.

Key To The Best Arm-swing In Bowling

The correct arm-swing is back and forth motion that is straight like a pendulum. There are a couple of common things that a lot of  bowlers do instead, which can adversely affect the result of their delivery.

A significant percentage of bowlers to want to hold the bowling ball in the middle of their chest when they're in the stance. You're forced to move your arm sideways and back around your body for the back-swing if the ball is this far inside. This will throw everything out of whack.

Instead, hold the ball out to the side of your body (on the same side as your bowling hand) so you can swing straight back and forth.

 

Bowling Lane Play - The 3 Basic Lines

Information on How to Play the Lane.


Bowling Lane Play. - There are 3 basic types of bowling lane lines; open, medium, and direct. (Note: this is for right handed bowlers – reverse everything for left handed bowlers.)

Information on How to Play the Lane.

Bowling Lane Play. - There are 3 basic types of bowling lane lines; open, medium, and direct. (Note: this is for right handed bowlers – reverse everything for left handed bowlers.)

1. Open Line - The open line is inside from the 14th board on the bowling lane. The ball angle is directed toward the 6 pin as it is released. This is described in the illustration below. High revolution bowlers like this angle most the time.

2. Medium Or Indirect Line - The medium or indirect line is from the 13th to the 8th board, or the track area, on the bowling lane. The ball angle is a medium line directed toward the 3 and 6 pins as the ball is released. It is also described in the illustration below. Power strokers or tweener type bowlers like this line.

3. Direct Line - The direct line is outside from the 7th board on the bowling lane. The ball angle is directed toward the 1 and 3 pins, or the pocket, as the ball is released. It is also described in the illustration below. Most strokers like this line or angle.

The 10 pin in bowling - why we leave the 10 pin in bowling

First there are 2 different types of 10 pins. 

One is the flat or weak 10 pin the other is the wrap or ringing 10 pin.

1.  The Flat 10 Pin - The first type of 10 pin in bowling is the flat or weak 10 pin. This is when the bowling ball rolls weak into the pocket and is due to a loss of energy. There are two reasons why this happens. Either the ball has never gone into a roll, or the ball has rolled too early and lost all of its energy before it gets to the pocket. So you must recognize two things. One being which type of 10 pin you are leaving. The other is whether the bowling ball is rolling too early or not rolling early enough. To determine whether you are leaving the flat 10 or the weak 10, look at the 6 pin. If the 6 pin is lying in the gutter, it indicates a weak or flat 10 pin. If you are leaving a flat 10, you need more angle or a ball that breaks later and sharper. You can do this with a change in the ball surface, hand position, type of ball, ball drilling layout, or a change in ball speed. If the bowling ball is rolling too early, you need to roll it harder. If it is skidding or not going into its roll, you may need less ball speed.

2.  The Wrap 10 Pin - The second type of 10 pin in bowling is the wrap 10, or ringing 10 pin. This occurs because the ball rolls into the pocket with too much angle or too much speed. The bowling ball does not have enough end-over-end roll. If the 6 pin goes around the 10 pin quickly, then you are leaving a wrap 10. A reason for this may be you are rolling the ball too hard. If you are leaving the wrap 10, you normally need earlier roll or more end-over-end roll. You can do this with a change in ball surface, hand position, reducing your ball speed, type of ball or ball drilling layout.

A Basic Rule of Thumb.
1. If the 6 pin is lying flat in the gutter, it is a flat 10 pin.
2. If the 6 pin flies around the 10 pin, it is a wrap or ringing 10 pin.

Let the 6 pin be your guide in recognizing your adjustment.
Note: Learn to recognize the type of 10 you are leaving, then learning how to adjust.
This is the key to increasing pin carry and a higher scoring potential..
