Title: Help wih Emerald
Post by: cooksey on April 28, 2004, 02:28:06 AM

Hello all, I bought a used emarald, single drill, it was about a 1:30 drilling. Span was way to short so i had the ball plugged and redrilled wih the same lay out but with my span here is a rough diagram

o o  p

 cg

 o
 The pin is just a hair lower than the ring finger but not much. Anyway, got the ball back and threw it for the first time and when it turned over on the back end of the lane it started rolling over a finger hole I believe there wasn' enough oil on the ball to be sure. I threw it several more times with different releases and it did the same thing. I took it back to my driller and he wighed it and said that it had way to much finger and thumb wieght and so he drilled the holes deeper and put in a wieght hole this all helped but it still clips the holes on the backend. He said there was nothing he could do because no matter how he drilled it it would do the same thing. I have a high track anyway. Is there anything I can do or should I just sell it to someone with a lower track? Help me out here fellas hate to think I have thrown away money on a ball I can't use.

cooksey -- The drawing has the pin high enough that the bowtie should be above the fingers and the ball should flare slightly away from the finger holes.  Can you find the bowtie to confirm its location?  Are you sure something isn't different about this drilling, hole sizes, pitches, etc. that is causing a change in the release?  --  JohnP

I'm not a drilling expert by any means, but I have never heard of both thumb weight and finger weight on the same ball. I always thought it had to be one or the other.

Must be a typo Brickguy.  Maybe he meant finger and top/bottom or side.  Also it's unusual to need a weighthole on a ball with the CG in the grip center.  I'm not sure how it works with a drilled ball, but you might have the proshop find the CG using Lane#1's instructions.  It might not explain flaring over the fingers, but might explain the static weights.

Good idea on finding the CG Strider, as I have my Uranium label drilled with the "marked" CG 3/8 out, yet the ball has 0 side weight, so the original mark is wrong. This seems to be a problem with the marked CG's on Lane 1 balls from time to time.

Brickguy221 -- Lane 1 is the only company I've run into that tells you in their drilling instructions to locate the cg on the dodo scale before laying the ball out.  --  JohnP

Thanks for the replies guys. I was just quoting what my driller told me on the wieghts. Is there any way to fond the cg on a drilled ball?

Thanks, cooksey

cooksey -- The same method used for an undrilled ball will work on a drilled ball.  You have to have a dodo scale, though.  --  JohnP

Thanks, he has a scale and I believe it is a dodo scale. I will get him to check it. Thanks for everyones help in this. Hopefully I can get it worked out I really like the ball.

Thanks, cooksey
