We are trying to determine how to drill my wife's new FREEZE. I started out by looking at all the published drilling vs track information but the track on her present ball is like nothing that's shown on the web.
The lady throws a right handed backup ball with the back of the hand facing the pins on the downswing followed by a clockwise wrist twist at release which gives it the backup action. We're trying to come up with a drilling pattern that will give her more drive through the pocket but looking at the track, we don't know where to start.
The ball described was drilled for a lefthander.
Here's our problem: Everything seems backwards.
1. The AP(axis point) marked #1 which is visible to the bowler as it rolls down the lane is in the position shown. This AP however is closest to the track which says it's the NAP but why then is it visible going down the lane.
I thought the PAP was the visible axis point and the NAP was in the front of the ball toward the pins.
2. The distance to AP #1 is 7 1/2" from the grip midline which again says it's the NAP but then again, it seems to be in the wrong place going down the lane.
3. The track is on the wrong side of the ball for a lefthanded/backup delivery. The ball is tracking on the same side as a right handed hook ball.
4. The track starts out away from the grip and flares toward the grip, just the opposite of most balls.
Have you got any ideas of how to drill the new ball to fit what's happening here? Any help would sure be appreciated. Right now it hits like a cotton ball leaving a lot of splits.
Answer Can you send me a picture of the ball? I cannot open the link that you sent. Email me at collinspro2@aol.com.
Normally, when drilling a ball for a right handed backup ball, we drill it like it is for a left hander. This would usually place the pin near the middle finger in the layout. The CG would be to the left of the grip as well. How far left depends on the amount of flare you would want to produce in the ball. An extra hole may have to be added to bring the ball back to legal specs.
