Guys,
I just got off the telephone with my ball driller - Karl Wolf - a senior PBA member with 35 years experience in drilling bowling balls. Karl has advised me to either contact Brunswick or take advantage of my extended warranty from the distributor and get a replacement.

Karl is familiar with the Twisted Fury as he owns one plus Brunswick had sent him just the core or weightblock which is mustard colored and is close to the size of a grapefruit.

The primary pin on my ball is located 1 1/4" above the fingers on the centerline while the secondary pin is 3/8" to the right of the thumbslug.

The standard thumbslug measures 3 1/8" long. Karl as a matter of procedure drills his thumbholes 2 7/8" deep so that there is a minimum of thumbslug to cut flush to the ball surface with his drill press router. I stuck a piece of wire down the wormhole I discovered - the bottom of the wormhole was exactly 4 inches from the ball's surface. Therefore the wormhole itself was 1 1/8" deep from the bottom of my thumbhole. I shined a flashlight down the wormhole but could not see anything that resembled what might be a mustard yellowish weightblock. I could see something red at the bottom of the hole.

Karl recommended that just the mere fact that the ball has a void in it is enough to warrant sending it back.

I would think so too. Let us know what happens

Erin,

I just got off the phone with Karl Wolf, my driller. Karl just got back from Buffalo, NY, where one of the people he met with was a Brunswick rep who had worked on the Twisted Fury in 2007. According to the rep the manufacturing process involves using some sort of straw where the mass bias locator pin goes and sometimes a hole is left in the weight block. Supposedly this hole has no effect on the performance of the ball.

I did try the ball out the day before I spoke with Karl and was pleased at how the ball reacted. In other words I had planned to keep the ball regardless of what Karl reported.

So all is well.
