Coverstock all the way to the core?
« on: June 14, 2006, 06:54:54 PM »
I set my Action and New Standard side by side and looking at the weight hole i noticed 3/4 inches of coverstock on the action at best, and the NS went all the way down as far as i could see.

Are all LM/L's balls like this?  If so these balls are worth way more than we realize.

I am looking to eventually trhwo alot more LM/L balls.

Currently in the 6 ball roller:
14lb. EPX-T1 - Stacked  - Heavy oil
14lb. Action - Stacked - Heavy/Medium oil
14lb. Absolute Inferno - 1:30 - Medium oil
14lb. Sahara - 11:50 Length - Medium oil
14lb. New Standard - Stacked - Medium - Dry
14lb. XXXL - Stacked - Spare ball

C.O.R., or better known as coefficient of restitution, is the amount of energy returned to the pin as the ball contacts it.

 In basic physics, it is known that for every action there is an equal and opposite reaction. C.O.R. is just the number that tells us how much of the energy of impact is returned to the pin upon contact. The higher the number, theoretically, the higher the pin action due to the impartation of a higher percentage of energy returned.

 And as far as cover all the way down to the core, faball ( and I'm sure they weren't the only ones ) ) used to do this with all the old urethane hammers back in the day. Many ball makers soon followed suit.

  Now, ebonite has done a study of this very subject and has come to the conclusion ( or so the article I read said ), that thin coverstocks over a larger inner core lets the ball have a more consistent reaction and more carry properties due to improved angle of entry.

 I don't remember where I read the article, it was in a magazine down at the bowling center. I will look next time I'm there and see if I can find it. If so, I will post what magazine it was in.

Ah, so that's why I've seen nearly two dozen ebonite balls with cracked covers personally!!!!

I believe that the article on this subject was in a quarterly Pro Shop publication put out by Ebonite although I can't remember which quarter. I save but they are at my shop.

Therefore, a 15lb. ball has a core that is 1 lb. lighter than a 16 lb. ball and a 14 lb. ball has a weight block that is 2 lbs. lighter. The more weight take out of the core, the less effect it has on the ball reaction.

So basically, a 14 lb. balls weight block/core has little impact on the ball reaction
 


Does this mean that companies like Brunswick, Lane 1, Track, Storm, and other such companies make a 15# ball to hit similar or close to a 16# and a 14# to hit similar or close to a 15# and 16#, but when L/LM makes a 14# ball, is it not nearly as strong as a 15# and 16# and a 15# not nearly as strong as a 16#, and etc.? I don't know anything about it and that is why I am asking, but the above statement causes me ask this question as I would like to know whats true and what isn't.

If that would be true, then maybe that explains why a friend of mine could never do anything with 14# L/LM balls and not able to average over the mid 170's, but when he got rid of them and switched to Storm and Ebonite, he immediately jumped overnite to the 195-200 average range with 14# balls from those two companies.

Sure, that must be the reason ...

How can you even think that way?
