weird weight shift
« on: April 18, 2005, 01:08:28 AM »
I have a 14 lb time zone that I drilled a while back.  I never had a scale so I would always make sure I kept the balls cg close to the center grip.  I recently got a deal on a kaufman scale and decided to weigh a bunch of my equipment just to be sure it is all legal and everything was except for my time zone.

I had drilled the time zone with the pin under the ring finger and the MB directly under the thumb.  the cg mark was 1/8 of an inch to the right of the centergrip line and directly in the midline of my span.

When I weighed the ball it had 1 1/8 oz of positive side weight.  I could not believe it.  So as an experiment I used the target weighting system to remove weight from the ball to bring it legal.

I now need to take the ball to the lanes and test it out.

Anyone else have this problem with a time zone?

Did it have a bunch of starting top weight?
Could the markings (CG or MB) from the factory be off?

er.. I couldn't help you much with this cause my Time Zone, same 14Lbs was drilled by my pro shop with everything done.

My time zone had a really big X-hole. heard from my pro shop that the side weight is a lot, might be due to it's core design? not sure.

hope it helps.

quote:
When you drill a ball without having a scale you have to assume the balls CG was correctly punched at the factory. We all know what can happen when we "assume" so I'm not going to go there. In reality the CG punches are often mismarked and on balls that are mismarked the TW is usually off also. It's just good drilling practice that we weigh a ball before drilling just to make sure we know what we are dealing with.


precision


Well said.

The good news about your Time Zone is the Pin and MB should've been used to lay the ball out, so its not like a symmetrical core that would have completely not been the layout you had thought you put on the ball, eg. You lay the ball out  to be 4 1/2 @ 45 degrees and instead its a 0 degree layout.  In the future though, any symmetrical ball I'm laying out I always check to make sure the CG is marked properly first.  Saves headaches.

Under the right conditions I would have used a scale because often times the cg's are mismarked.  However I have never had one marked this bad.

The fact is that I kept the pin under ring and the cg in line with the midline so this ball had to be mismarked by at least 1 1/2 inches.
