9" pin on Storm Trauma Pearl
« on: October 12, 2004, 08:58:43 AM »
Any ideas for drilling a ball with 9" pin?  It only has 2oz top weight.  It seems like I heard you can draw a line 12-13" long from the cg through the pin and this would give you a new cg.  Basically, you marking a new cg 180 degrees from the existing one using the pin as the mirror line.

Anybody heard of that?

This couldn't really be done because the top weight would become bottom weight and after putting the holes in it you would have way to much bottom weight to be legal max allowed is 2 oz and you would have that before it was ever drilled. I would take it somewhere and have the CG verified since they are often mismarked and having a 9" pin it is definitely a blem. Some blems are just a simple mismark of CG or MB.

The ball is a Blem.  I forgot to mention that.

Also, I thought 3oz was the max top/bottom weight of a ball.

I stand corrected you are right it is 3oz.
I never see drilled top or bottom weights that come close to being illegal so my memory needed a refresher.
I still don't see how you could do it that way because on average you remove 3 oz when drilling the fingers and thumb.

How about inverting the pin.  In other words draw an imaginary pin 180 degrees from the existing pin using the cg as the mirror line.  This would keep the top/bottom weight like normal but invert the core.  So, instead of a 9" pin, I would have an imaginary 4.5" pin.  What about the MB?

Snowman is correct. Invert the pin by drawing a line from the pin 13 1/2" thru the MB. This will leave you with a 4 1/2" pin.

You can use a quarter scale to do this easily by placing the tip of one end of the quarter scale on the pin. Then the tip of the other end will be the new pin.

Now drill the ball accordingly with the new pin and MB markings. =:^D
