First of all, you need another dimension before you can start. You need to know where your CG will be in relation to your PAP. Lets see we want to drill this ball Stacked Leverage so both the Pin and CG will be 3 3/8" from your PAP. Here is how I was taught to lay a ball out.
1. Take your Quarter Scale and place it on the ball with the 0 mark on the pin. Now your going to have an idea where the PAP is going to be because of your hand, right handed will have the PAP to the right of your grip so you would measure 3 3/8" to the right of the Pin, alright. So place this mark from the Pin 3 3/8" OK, no take the quarter scale and draw a line arbitrarily from the mark, usually I make this line perpendicular to the pin.
2. Take your Quarter Scale and now place it on the CG mark on the ball and repeat step one placing a mark 3 3/8" from the CG and draw a line.
3. Where the two lines intersection is the PAP for this 3 3/8" stacked leverage drilling. This is the point where the Pin and CG are both 3 3/8" away from the PAP.
4. No take the Quarter Scale and measure down 1/2" for your own PAP in this case and place another mark.
5. Now this is where it gets a little tricky and trial and error are needed. Take the quarter scale and place either the 5 1/4" mark or 0 mark on the mark you made 1/2" down from the PAP. Now hold this point and pass the edge of the quarter scale on the CG and draw a line along the Quarter Scale. Now just measuer over til you hit your 5 1/4" mark. This is the center of your grip. Draw a line perpendicular to the line you just drew along the Quarter Scale and then just measure up and down from the center of your grip to get your thumb and fingers laid out.
6. Depending on how long of a pin you have, the pin might be above or below your ring finger. Now, I stop and look at the layout you just did to make sure it makes sense. Do not get discouraged if the Pin and CG do not line up like they should in a Stacked Leverage layout. This is because your PAP is 1/2" up and becuase of the curvature of the ball. Also, keep the PAP laid out on the ball after drilling to determine if you need an axis weight hole after balancing. Usually, this layout requires one.
Hope this explains it a little bit. I know I wrote a lot but its hard to describe without have a ball and my quarter scale in my hand. Really, how I learned was watching my friend layout balls for years and then trying it myself on my own equipment.
Good luck
