That's what my ball driller advised me to do. Not sure if it makes a difference or not though.
I was wondering if only balls with filler were suspect to crack until my Lane master terminator cracked. I guess balls just crack after time. I am trying to rotate my equipment so they all get equal use. Maybe if I keep them in play they wont get brittle or dry or whatever they do to crack.
I seriously doubt it. I have had maybe 50+ San Antonio made balls from the original Columbia 300 family: Columbia, Track, AMF, MoRich, and several from the 900Global era made in the same plant. I have had exactly one to crack, a Track Sensor that sat in its box for 3 or 4 years.
Since 1995 I have stored them all in my basement with humidity range of 40 - 60% and temperature range of 55 - 70 degrees. They sit either on an indoor/outdoor carpet, in front of my ball rack or in their original box in the original plastic or cloth bag on a wooden shelf. Some of these balls sit for 5+ years before I think to dig them out and try them again. I do not rotate them in the box so that a different part of the surface is supporting the ball. None other than that one Track ball have cracked.
I suppose, to a certain degree, I am lucky. I do know my driller is always careful about drilling: slow, sharp bit, bevel all holes, minimal use of super glue. The pin is either at least 1/2" -3/4" from any hole or drilled out completely. Standard precautions.
