Title: Find the CG on C300 balls?
Post by: johns811 on March 04, 2004, 06:03:04 PM

Is the punch mark on C300 balls always the same spot somewhere imbedded in the C300 logo? I've got a Spirit and I can't find the cg punch mark. I've looked the label over with a magnifier and still can't see any obvious mark. I checked an old B/G messenger and a Scout and it is difficult to find on them also.

Any help appreciated.

Thanks

The CG mark should be in the logo somewhere.

But Columbia is bad about miss marking the CG. I would say 10% of the time the CG is off by 2” or more. I’ve seen the CG on the wrong side of the ball. All manufactures miss mark CG’s from time to time.

You must use a scale to balance the ball. Otherwise you are drilling in the dark.

You can find it using a scale. Here's how. http://www.lane1bowling.com/tech/cg.html or the animated version

Yeah each columbia ball differs. Some of their balls use the pro grip symbol, and some have a little punchmark sitting in the logo.
