coverstock longevity
« on: June 27, 2015, 07:00:30 PM »
I came across this post about why bowling balls lose their reactions. (http://www.motivbowling.com/forum/viewtopic.php?f=4&t=15174), but what I'm confused about is why motiv can last so long without losing their reaction that quickly, but when i use hammer or columbia equipment, that reaction doesnt last for more than 20? I wipe my ball after every shot and clean after every session, but it just seems to lose that reaction so much faster than my motiv equipment. Am i doing something wrong or is there anything I can do to keep that reaction for a longer period of time?

I remember years ago when The One by Ebonite was notorious for coverstock death and soon after that, Ebonite just had that reputation to bad coverstocks not lasting. I've generally had a lot of luck with the Track 505T lasting for over 5 years without even an oil extraction. Only ball from Motiv that I've heard issues with as far as coverstock death was the Raptor, which I did lose some reaction with it within half a season even with a light resurfacing. Best thing anyone can do is clean their equipment after every session with a strong cleaner like Clean N' Dull or Ultimate Rejuvenator.

So your losing reaction after 20 games, If all your doing is just wiping and just using some cleaner on it I'm not surprised.

More than likely you need to touch up the surface, you know take a abralon pad or piece of sandpaper to it.

That's one of the thing's mentioned in that 4 year old post see: "2. Restore the surface."

Your surface texture is changing everytime you roll the ball down the lane. So depending on just what surface you have on the ball, your reaction can change fast.

Brunswick hijack. You don't say. I guess if the OP cared, he would have asked. Motiv can survive in Michigan, Nick. How come B couldn't?

I do resurface after a certain amount of games, mostly when I see the reaction die i go and sand it with whatever.

I remember years ago when I first started following these bowling forums.  Most of the posters who preached the meticulous care of the cover stocks were Ebonite people.  I think covers have improved somewhat over the years.  Early Storm pearls were very bad for dying.  However Ebonite solids were the worst.  A former Ebonite staffer told me he was pretty sure part of the problem was the shell thickness.  Brunswick shells prior to 2007 were easily the most durable.   

I think the manufacturers have actually changed or cut back on the resin additives from the first couple of generations in the 90's.  It should be remembered that all resin balls are urethane with the resin additive.  The resin  basically improved friction off the oil without the aggressive shell prep that was standard on strong urethanes prior to resin.   This lead to a more extreme skid snap look that we would prefer to be tamed down a bit today.  If you think about it, we dulled stuff up in the 80's to try to get it to hook more.  Today we dull it up to get it to burn off energy earlier and smooth out the hook. 

In summary, shells have changed on balls since the introduction of urethane.  Before resin, it was hard to keep the shell in box condition partly because the lane polished the shell, but partly because even non resin urethane absorbed oil to a greater extent than we understood back then.  Original Black Hammer, and Columbia Black U Dots were terrible for longevity.

On the question of shell thickness, take a look at this Brunswick Gold Rhino Pro from 1994 and this Brunswick Strike King from twenty years later.





I know that thinner shells and more filler allowed companies to push the edge on RG and differential, but I have to wonder how much shell thickness has to do with longevity.

so theoretically doesn't this mean that equipment like the rocket/hyroad/IQs from the storm is gonna last as long as motiv since the coverstock is thicker than their other thinner equipment?

Shell thickness has long changed with the larger cores used in many bowling balls. As a ball whore who drills more then a normal person should since 2001(year I stopped using inserts)  I've had a total of 3 or 4 bowling balls crack….. I think 4 and this is out of probably a minimum 250 bowling balls.  I know plenty of of people who drill maybe 4-5 a year max and have at least one crack a year.

Why do you suppose that is?

Kidlost, if I go by what a pro shop is saying, do you bowl against Twister pins?  They are supposed to be the primary reason for many balls cracking around here.

(and yet, none of the house balls have cracked)

As for coverstock longevity, I have a couple of Visionary balls that I have been using for 15 years and they seem to have not lost much reaction.

M2A we have four local houses and as far as I know none do. Urethane house balls are magic

I have owned hundreds of resin balls over the last 20+ years.  Only balls that ever cracked on me were an EPX, and a pearl Ebonite ( forget which one ).  However had plenty die on me.  Trauma, Green Bolt and X Factor were the worst from Storm because they were so good out of the box.  Several Columbia balls from late 90's were also bad, along with every solid from Ebonite.  Original Mission ( pearl ) was very good and long lasting, but when it finally died we couldn't bring it back.  Longest lasting balls were Raging Red Fuze, Inferno, Vapor Zone, Absolute Inferno Pearl Fury.  I am not at all good about maintenance so keep that in mind.

My new Delirium cracked last week . It's the first ball to crack on me in a very long time.
