Brunswick Nexxus and Rotogrip Defiant Soul....I had both on a ball shelf (rotate every 2 weeks)......Both out of warranty :<.

Bet you had finger inserts.

Beveled finger holes before adding inserts? 3/8" bridge?

Cracked bridges are easily fixed and won't have any effect on performance. I don't think any ball manufacturer would do anything about a cracked bridge anyway. My spare ball (Lane #1 XXXL) has had the bridge crack twice several years ago and it's still doing just fine, including being used as a strike ball for shorter/drier conditions.

I agree with beveled finger holes. Less Glue.
I use 3/16 bridge with inserts. The Vulcan peace symbol is uncomfortable for me while bowling.

Yes,
And for total honesty....I'm not so sure the bridge width is 1/4....both seem a little short from my view....

I don't know if there is an real answer or solution I have a friend who doesn't use inserts, take care of his equipment religiously still has problem with cracking he uses 5/16 bridge because any bridge wider than that hurt his hand i also can't use an bridge wider than 5/16 tried it years ago it caused me release problems.

I have had a bowling ball sitting on a cold damp basement floor for years and it never cracked. I have also had a bowling ball in my trunk over the summer (forgot I left it there) and it was fine when I discovered it three months later. On the opposite end, I have had two bowlings that were sitting on a rack at room temperature and they both cracked.
I always wonder if the cracking of bowling ball is similar to what you see in a windshield. There might a small weak point and finally it goes. I have no clue what causes that weak point to happen. It just does on some bowling balls.

Most people that drill bowling balls have a standard drill that they use on the finger holes along with bevel to help to prevent cracking bridges. I know several drillers that uses 3/8 left on middle finger and 3/8 right on the ring finger and adjust on the amount of pitch due to flexibility of the bowler. Several years ago I had a driller that drilled several balls for me that the bottom of the finger holes touched at the bottom and every one of them cracked over time.

Bridges should be 1/4 inch, and total pitches should add up to 3/4. So, you can go 1/4 1/2, 1/8 5/8, 3/8 3/8, whatever adds up. Following these rules, you will never have a bridge that meets at the bottom.
Now me, I don't bevel the fingers at all, and don't use grips. Started doing that about 13 years ago. On a first drill, I've never had a ball crack around the fingers.

And yet, for several years, all my finger holes met at the bottom, with a hole between them, because I asked my driller to use zero left/right finger pitch. The bridge was always 1/4", he beveled all holes, I use finger grips and not one of the 15 or so balls cracked. I still have most of them.

Stopped using inserts in 2001 and have yet to have a bridge crack. Could be several factors but lucklily I have not delt with any of them lol.
