Guestions about the Gemstone
« on: July 04, 2009, 07:48:52 AM »
Is the Gemstone asymetrical?  I think it is.  If you cut the diamond core as shown in the picture the right side of the diamond has the middle of the diamond triangular and the left side if flat.

So would this ball be better for left handed bowlers or right handed bowlers?  It can't rotate to its axis the same for lfet handers as for right handers.  Do you have to drill the ball backwards to get the same effect from left to right?

With only half the diamond, will you get the turn and carry that you get from a full sized diamond core?

Thanks for reading,

I haven't really looked at it, but if it is asymmetrical, why would it have to be better for one hand vs. the other?  Every other asymmetrical can be drilled equally well for either hand, provided the layout is correct, or am I missing something unique about this ball?

Strider,

 I don't know.  Look at the picture of the core a couple of posts down.  I don't think Asymetrical bowling balls are good for both left and right handed bowlers.

If you take a diamond, split it in half, pin on topn.  Now the lobe of the diamond is set off to the right in the core and the flat part of the diamond is facing the left side.  So if you're right handed you have more weightblock on the right and less weightblock weight on the left.  The picture shows it well.

Same thing with asymetrical weightblocks that have armetuers, or arms, legs, flip blocks or what ever makes the ball asymetrical.  If that weight from the additional is not evenly displaced on both the left and the right side of the weightblock, then I would think if the additional weight or flip block wsa on one side, the additonal weight would have a more dramatic difference then the side without the added flip block or armetuer.  Some of the earlier asymetrical weight blocks like in Ebonites Low Torque and High Torque and even some of Tracks first asymetrical cores had a flip block on the top of the core usually facinifg right putting more of the weight and the flip block on the right side.

There is no way this ball would act the same for a right handed bowler and a left handed bowler.

What do you think?

I asked this same question the other night on the Miscellaneous forum using the 900Global Link as the example. What was finally said that made sense to me, was that you're actually looking at a cutaway of the side of the ball. In other words, the core is not offset to one side or another, but to the front or the rear, and the MB marker (if the ball had one) would come out the front of the core and be on the righthand side of the core picture.

So if you were to drill it with the MB in the thumb, the core would be pointed out of your thumbhole. Whether you put it to the left or right of the thumb would orientate the core as needed for lefty or righty.

To me, this looks like a version of a Power Groove, Tropical, or Tornado. Pancake with an offset puck. The puck is replaced by the cut diamond.

I have a link and its a pretty decent peice, gonna be real interesting with the gemstone cause if the description is right IE hybrid ISO pearl (pearl version of the dynamo x2) the cover has to be way stronger then the pearl s30 on the link, I can play 5th arrow with the link on a toasted up shot

If it were an asymmetric core with a intermediate diff of over .008 most manufacturers mark the mass bias. If this ball is not marked then I would assume the mb strength is not strong enough to make a significant difference, and therefore be drilled as a symmetrical core ball.

The Gforces MB's were marked and they were only .007

And? Marketing delusion, I'd say. Hammer used to mark on some asymmetrical core balls a "LMB" (e. g. in the Vicious line), which actually means "Low Mass Bias" - which has/had no effect on the ball's reaction. Ebonite did the same.

Has anyone tested this ball and can share their findings?

Between the Gemstone and Chainsaw, which one would be more ideal for burnt lanes?

Just a guess. I know the Gemstone isn't out yet, but want to get an idea.

If the Gemstone is supposed to be for "Medium" conditions then I would have to say the Cahinsaw for burnt.
