Sometimes you might get a ball with a large Pin to CG placement.
This happens alot with Blems, x-outs and Pro Pin balls. which are all
just another name for seconds.
You wonder how to lay them out. A simple way to make it easy is
to located let's call it the "anti-pin". This is the point 180 degrees
around the ball directly opposite the pin.
Look at it this way, The normal pin is the Northpole and the anti-pin will be the southpole.
First thing before you start, weight the ball and verifiy the cg positon.
Just incase its mismarked.
To find the anti-pin just take your quarterscale and project a line halfway around the ball from the normal pin. Next turn the ball a quarter turn (90*) and project another line around the ball from the normal pin.
Where these lines cross will be your new pin location(anti-pin). Now you can layout the ball normally, using this as the new pin location.
Example-
A ball with a 9" pin to cg distance, the mb located between them.
PIN------MB---CG
[-------9"-----]
Project the pin 180 degree's around the ball.
Now you have a 4" pin to cg distance.
PIN----CG---MB
[-----4"-----]
What you have done is invert the core. The reaction for the ball should basically be the same doing this.
This works with symmetrical cores well, as for a asymmetrical core you'll have to check the MB position. Should be able to do it though.
