Plugging effecting c.g??
« on: October 24, 2003, 11:52:17 AM »
Was talking to a friend about him getting a ball plugged and re-drilled, talking about layouts etc. Told him he should put the pin above the ring finger and c.g below maybe to the right a bit for the reaction he was after. Bout a 4" pin, give or take.

Caught up with him after and another driller had come in when they were punching up the ball. He said because it had been plugged that would effect the c.g location, so he made them put the pin a least 2-3" (from memory) above the ring finger and the c.g just underneath it, and said the c.g "was actually out to the right" because the ball had been plugged.

is this actually right?? i've never heard of plugging effecting the c.g location or pin, or anything. i thought this was quite strange and the ball reactions not as good as it could be.

I can effect it slightly as the plug material's density might not be exactly the same as what was removed during drilling.

Also many balls have the CG mis-marked. A ball should be balanced in the proshop before drilling so the weights are correct.

I would guess for it to be off that much that the CG was mis-marked in the first place.

Yes, the CG can/will change with plugging, as the plug material is lighter than the core material. It's always good to check for the CG before drilling a plugged ball or even a new ball for that matter, as PIN said, the CG can be mismarked to start. Finding the CG is very easy and very important. You can go to the Lane 1 website in their tech section and it shows you how to find it. =:^D
