Is this a fair description of how to layout a ball.

I'm trying to explain laying out a ball to some else and came up with this.
(He thinks the method used to locate the PAP (the horiz. by vertical measurement) is antiquated and not accurate.)


I'm posting this as a reference, this would be how you layout a ball.
With a Dual Angle layout and the standard PAP measurement system
(https://www.ballreviews.com/proxy.php?request=http%3A%2F%2Fi174.photobucket.com%2Falbums%2Fw89%2Faloarjr810%2Fmisc%2520files%2Flayoutexample_cr.jpg&hash=9e4183eab2d2291376d0e6241e041a23555adc0a)

Layout" 45 X 3" X 30
1-Draw a reference line from Pin to Mass Bias

2-Draw a line at a 45 degree angle to the reference line from the Pin.

3-Now on that line measure 3" from the pin and mark that spot, that's the PAP

4-Next draw a line a 30 degree angle to the Pin to PAP line, this is the VAL. (Vertical Axis Line)

Now we are going to project back from the PAP to the center of the grip
5- From the PAP measure down 1" on the Vertical Axis Line.

6- Draw a perpendicular line from that point (That's the called the Midline, it's A line that's 90 deg. to the VAL)

7- Now  measure over 4 3/4" from the VAL and make a mark. That's where the center line of your grip is.

Your can read this bizarre thread here:
http://www.bowlingboards.com/threads/9967-PAP-Identification-Method-(-amp-Terminology) (http://www.bowlingboards.com/threads/9967-PAP-Identification-Method-(-amp-Terminology))

Here's a sample:

Quote

In my opinion the PAP location should be the equivalent to the North Pole, and the line from the PAP to the center of the fingers (not including the thumb) should be the equivalent to the Prime Meridian.

Measure from the PAP to the center of the fingers gives you a longitude, latitude value, longitude being 0 degrees.

Diagram looks to be 45X3"X30 ;)

If the PAP is 4 3/4" over and 1" up your revised procedure is right.  --  JohnP
