Anyone using a Determinator?
« on: March 18, 2007, 04:21:40 PM »
I have  Determinator, my understanding is the MB or PSA on a ball is on the Y axis, and the MB Diff is the difference of the Y-axis and Z-axis, well this is my understanding, correct me if I am wrong.

Question, can a ball have the same MB value on the Y and Z axis?  If yes, will the Determinator be able to to find out the MB? or it won't coz there will be no MB diff, I mean will the ball stable on the Determinator?  I am talking about an undrilled ball.

A ball can have either a Y or Z spinning core.
If the marks you make on the ball are very close to each other the ball has a Y spinning core.
If they are far apart it has a Z spinning core.

This part I sure understand.

I am talking about same value on Y and Z axis.  possible?

If you are asking if a ball can have an equal amount of dynamic potential on both the Y and Z axes then the answer is no.
MB differential is found the same way as RG differential in that the number comes from the difference between the High and Low RGs whether it be the value through the pin or the PSA.
For example (arbitrary values):
RG diff (x axis)
high - pin 6.75 from PAP 2.50
low - pin on PAP 2.45
diff .050
MB diff (y or z axis)
high - PSA 6.75 from PAP 2.5
low - PSA on PAP 2.475
MB diff - .025
Basically it just means that the ball has RG differential though the pin (x axis) and perpendicular to the pin/through the PSA (y or z axis).

How you get the value? 2.475

I didn't use actual known values and just picked an arbitrary number that would fall within the legal limits.

Precision
I am pretty sure he was referring to asymmetrical balls and there aren't any current offerings that have muliple core protrusions to create mass bias. That is the only way you could have an equal amount of dynamic potential on both the Y and Z axes in an asymmetrical ball. I do wonder what would happen if you placed 2 protrusions that were 90° from each other about the x axis. I would think that you would end with a PSA that was in between them but who knows.

I am not limited the discusion either on symmetric or asymmetric core.

However, if the Y and Z value are the same and no stable PSA when undrilled, with symmetric core ball its easy to predict the drilled PSA, but on the asymmetric shaped core but still same value on Y and Z axis, it will be very hard to predict where you going to hit on the thumb hole, coz no way you can know the core orientation.  Yes?
