lefty 50,
If you question the positive axis point your ball driller came up with you can easily recheck it. I have always looked at drillers as I would a doctor. Many are specialists and many are general practitioners. You as the patient need to convey as much information as you can so they can properly diagnose your needs.
Your PAP is affected by changing the span, pitches in the finger and thumb hole also changing the way you release the ball can drastically change your positive axis point.
Just in case you have a general practitioner I would suggest you spring for a quarter scale and recheck your PAP. This will also give you a tool where you can layout the drilling you want then have the driller punch the holes. I would also suggest getting a copy of your hand layout, if you don’t already have one, and recreate it on your computer. Microsoft Publisher is a good program to use because of its ability to create circles and lines along with text boxes.
I took a ball and laid it out using a track that was 1-1/4†off the fingers and 1†off the thumb and came out with 4-1/4†over and 1/2 “ up. That is more or less along the line of what you though it should be.
If you have a quarter scale you can roll your a plastic of urethane ball, preferably a solid color, and trace the oil line. Establish a centerline and a midline. Off the oil line draw two lines perpendicular to the oil line. Draw one about an inch below the fingers across the ball and one about an inch above the thumb across the ball. Where these two lines intersect will be your positive axis point.
Most bowlers have benchmark release that they normally use. This is the release that you want to use when determining your PAP. If you are bowling on super wet or dry conditions most bowlers will change their release and in turn their axis point will change but you still want your equipment drilled to reflect the release you normally use.
