I store my older bowling balls on a wood rack in my basement. The temperature is a constant 65*.No direct sunlight. Every week or so if I go down there to do something I move the balls around. I have had two balls crack. A DV8 Endless Nightmare and now a DV8 Thug Unruly. Both cracked all the way around the ball. I have 2 older Brunswick balls and a DV8 Ruckus Feud on the rack. Any reason for the cracking and anything that can be done to stop it ?

I'm having a hard time believing that rotating balls, avoiding wooden racks, and sacrificing chickens will protect a bowling ball that has already experienced throws onto a lane (thump) into multiple wooden pins (thumpity thump thump), stop suddenly after 65'+ (thwap), and returned back through the metal ball returns.

C'mon, get your sacrificing right. You need to sacrifice goat entrails ion your keyboard.

Since this activity doesn't often crack a ball from the outside, I'm guessing it's probably more how temperature/humidity changes affect the different composite densities and applied to irregularities in manufacturing.

It's not the densities of the 3 materials, coverstock, filler, and core that cracks them. It's their different rates of expansion, when subject to rapid changes in humidity and temperature, that can cause them to crack.

Concur; that was the intended thought...

...and also concur goats work as well as chickens.
