balance hole

Post by turbotwister »

after they made changes about bowling balls that had a balance hole, I had my pro shop plug the balance hole in an older ball. will that change the roll/reaction, or should I have the ball plugged and re-drilled even though it still fits? thanks

I am not a fan of plug and redrills. It is too dificult to predict the the final outcome.
Roll it and find out. It may end up being in a different place in your arsenal but still usable.

Depending on the location of the balance hole.
P2 balance holes were used to adjust static weight and had little affect on the ball motion,

I had several balls that were motion holed. Once plugged they no longer fit into my arsenal and went into the dumpster.
I have only 1 ball left that has a plugged balance hole. P3 It is not the same but it is still usable.
I had the use of a Determinator and the results were as if the balance was smaller.
The plug material was not as dense as the core material that had been removed.
The PSA did not move completely back to it's original location.

....that's kind of what I was thinking about that,as it has to change the roll somewhat. It just doesn't seem to be the same as it once was. thanx

We've plugged, literally, hundreds of balance holes, cannot recall anyone having issues with performance. ***None of the holes were in the P4 location.

We also adjust the surface of the ball accordingly. Arguably, surface probably has more impact on ball reaction than plugging the weight hole.

TomaHawk, do you adjust ball surface to factory or accordingly to what your lanes call for?

For the most part, we adjust the surface according to how the lanes are playing.
