Pin position
« on: June 23, 2009, 05:57:51 PM »
Pin up or pin down... Does it really mean anything?

I have my VG drilled pin up 1.25", and it measures out at:
28x4 3/4x55 dual angle drill. With the MB 4.5" to PAP distance.

I just got a Rogue Cell, and was planning on trying out the Double Thumb Layout, but when I get all the measurements, and transfer them to the Rogue, the pin is going to be 2" above the center of the finger hole.

Does the actual pin placement in relation to my finger holes actually mean anything, or should only the Pin to Pap and degree angles matter?
The Layout on the Rogue came out to a 65x4x30

Also, when Morich says "The Double Thumb drilling technique will result in the drilled ball having the strongest mass properties without risking the chance of the ball flaring over the balance hole."

What exactly does "strognest mass properties" translate to in ball motion?

Pin in relation to fingers up/down doesnt really matter.  It is the Pin to Val distance that does.  The shorter the Pin to Val distance (pin way above fingers) the quicker the ball will respond to friction.

Pin higher up and closer to the VAL will leave the ball at a higher rg (compared to lower below the fingers) therefore the ball will store more energy for the backend and a quicker response to friction(like said above), will be more angular and snappier..(for that given pin to pap distance)

 As always take cover and lane condition into consideration.

funny thing is .. it is the PIN to VAL distance(pin buffer) or VAL angle that is used as the terminology but in this instance it is actually the location of the holes that affects the reaction.  A pin higher up ,the finger and thumbholes will take more weight out of the side of the core leaving the height of the core intact and also increasing the differential in the ball.

It isn't the pin being near a magical line called the VAL that actually affects or creates the difference in reaction.. it is the hole placement in relation to the core.

The double thumb basically puts the thumb hole at 6 3/4 from the pin ... right in the side of the core.. and the weight hole is 6 3/4 from the pin .. also right in the side.  This increases the differential which increases the flare with the 4" (close to leverage) pin position.

Your Rogue cell should flare a ton and want to hook.. The MB position should keep it from wanting to roll too early though.. should be strong with a big backend.. ( depending on cover,lane condition, speed, revs)
