Basic example of how to layout a ball

Rating: 2 votes, 5.00 average.
This is a basic example of how you layout a ball using a Dual Angle layout.
Tools used a Pro-Sect Quarter Scale and grease pencil.



The Layout used is 45 X 3" X 30
P.A.P. Location: 4 3/4" Horiz. 1" up Vertical (AKA: 4 3/4"> 1"^)
(The layout will look slightly different actually on a ball, this is just to show the differing parts of the layout.)

1-On the ball 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.
