Title: MoTion Hole and CG Placement
Post by: TheGom on August 20, 2015, 05:21:50 PM

I have a ball already drilled that looks correct for a motion hole based on my PAP, except that the CG marking is 1" right of the center line (RH Bowler)

How close does the CG marking need to be to the center line or does it need to be on it period?

Thanks

Here's a MO quote:

Quote

When doing a MOtion Hole layout, there is margin to place the pin any pin to PAP distance you prefer. You can place the pin in any relationship to the finger holes you like following the rule that you either miss the pin with the finger holes or you remove the pin completely. There is not much latitude with the cg to avoid static weight issues. Keep the cg on the centerline of the grip within 1" of the center of the grip. That's about it!

Look at where the motion hole is going to have to go to avoid your track.  My motion hole tends to be left of the center line when looking at the holes.. So it adds positive weight to my ball.  Just make sure that when you add the motion hole it doesn't give your ball illegal side, finger, or thumb weight.  You are usually ok with top weight as you have 3 oz to work with there.
