I tip my cap yet again to 900 Global for this new technology ( CFT ) :) If you've ever drilled up a ball then you'll know what IM talking about 8) They have now taken the guessing game out of the drilling process in how the #'s change when you drill a ball. this will make it much easier now with out changing the CG Diff or MB #'s. 900 GLOBAL continues to be doing there home work and all the extra credits possible to make there line the best it can be.. thanks 900Global.

I want to see if the marketing is actually true. If it is, it is pretty awesome.

I would like to see this core with a S-80 something cover. we might have something in the makings here ;D I get 1st dibs on it if there is.. LOL

At least it looks like it's not just a interesting shape/object they stumbled upon that has properties that have no correlation to rotational physics once placed in a solid sphere, much less how those properties are affected by holes...

Hey guys! More info to come soon on the website! An article and illustration will explain the whole concept. I'll post a link when it's up. I think Dale should be done with upload tomorrow.

Thanks Nick. I'm sure I'm not the only one who has been racking my brain over how this is possible.

Simple. Nick dabbles on the dark arts.

Here is what they had to say about the ( CFT ) Utilizing Fluid-Flow Design Tactics and Composite Material Flow Principles of Chemical Engineering, we’ve created something truly unique; the first dynamic core to feature Mass Property Stabilization. But what does this mean for you? After drilling, the asymmetric Composite Flow Technology Core (CFT) maintains its designed Rg and Differential values, allowing bowlers to get exactly what they want and expect out of their ball.
When evaluating bowling balls for your bag, you may often look at the Rg (Radius of Gyration) and Differential number associated with a particular core. Understanding these values helps you relate the expected strength of the core and type of ball motion to your specific style. Unfortunately, what you don’t see is how these numbers change after actually drilling the ball. Based on the ball layout chosen, certain areas of the inner core are removed during drilling, altering the core dynamics away from their designed values.
The CFT Core was designed specifically to maintain the differentials that fluctuate in other designs due to drilling. With the CFT Core, the Rg and Differential numbers advertised are the core numbers you’ll get when you throw the ball. That means NO MORE GUESS WORK!
if your not excited about this yet, this might seal the deal :)

We heard lots of similar marketing about the Bank's "self righting core", but it was just another ball. Probably not one of their most popular either. Knowing what you'll get after drilling is great in theory, but it might just hurt the experienced drillers who already knew how to lay out a ball properly for their different bowlers.
-
One of my concerns was if drilling holes in the ball doesn't change the diff then how would I be able to add a weight hole to tune a reaction for a customer. Does this mean that a weight hole drilled in either P1 or P4 will still react the same?

I loved the SRC, so bring it on!

Is this going the same direction that the No Mercy did in some circles? Be sure your shop operator reads the directions first... :P

The P1 - P4 holes have more or less effect depending on how much core is removed. If the core is shaped so that you will only be drilling out cover and filler with the "P" holes, then no they will make a much smaller difference.

Are cores typically poured with high Reynold number flow? Under laminar conditions would this issue to be adverted...that is unless the viscosity of the outer material was very high... Any different from pouring plug material into a thumb hole containing a "shop candy" from the ice cube tray? Tap a few times with the rubber mallet to release the bubbles...no?

I was thinking about this as well. Do you think voids are what they are worried about? I was wondering if lower pouring velocity or Rey No, would help this as well. I do not know all the detail though, about time restraints on the material in the mixing tank or how long it takes to pump out hundreds or thousands of these. Designing a core to help mix the filler material properly, seemed like overkill to me. Almost like worrying about the manufacturing process rather than the importance of what you are making. I mean are voids in the filler really a big problem?

I am a fan of 900 Global, and I joined this site simply to respond to the conversation on the CFT core. I also drill balls. There has been a lot of efforts in recent history to create cores that function to avoid manipulation of the undrilled specs through drilling. The most successful case to date is Seismic's Tenaci core, and of course Storm followed suit with the Crux.
I am going to roll my network for the first time, i just finished drilling it up and I can't wait. I love the new generation Global balls like the Moxie and the All Day but i had to have a network, the Dream can wait.
The CFT or the CFT2 in the case of the Network is undeniably awesome and unique.
However, Global, and others have been UNABLE to prove that the specs remain the same after drilling. They actually explained that it was impossible to prove what they BELIEVED to be true.
So while this core is actually pretty spectacular in form and function, and maybe revolutionary, it is remains unproven whether or not Global accomplished the mission of creating a core with specs that remain unchanged after drilling.

Radical did this with their patented finger scoop core in the yeti.

They can use the design software that creates bowling balls to get a very accurate idea of what happens to the ball after drilling. Ebonites blueprint software proves that.
Id rather have a core I can manipulate then not. They've spent a lot of time with layouts and weight hole locations to manipulate the balls reaction.
