At times it is suggested to drill finger holes deeper to maintain static weight limitations when using certain balance holes. A study was conducted to determine the effects on mass properties when drilling finger holes 2" deep compared to 3.5" deep. I used CAD software to model a double thumb drilling and study the effects of drilling finger holes deeper. The ball used in the study was a MoRich Frenzy at 15 pounds. The dual angle layout used is 65x4"x30 based on a PAP measurement of 5" over by 3/8" up.
