9 inch pin
« on: April 29, 2009, 03:27:37 AM »
Has any one ever drilled up a ball with a 9 inch pin????? If so how does it react compared to your other equipment???? I just punched up a Dimension with a 9 inch pin and will throw it tonight to see how she rolls.

Nor Cal, I'm not sure how to post pics on this site, but if someone can tell me i will post some up tonight or tomorrow. I know the CG is below the thumb and pin above bridge. An extra hole below and to the right of thumb hole quadrant. I will throw it tonight for the first time and let you know how it rolls. It scaled up fine, and it had a little over 2 on top to start with.

I threw my 9 inch pin Dimension last night on THS. It is definately more ball than what i was currently throwing. I am going to throw on the National pattern in the upcoming days to see how much volume it will handle. So far i am pleased with it. I could get into 25 thru the fronts before it started to lose carry, other than that it seems to be enough ball for the Nationals for the fresh Team Event.

I've never seen a 9 inch pin. That's gotta be crazy.

With a pin that long, the usual way of drilling it is to draw a line 13.5" from the pin through the CG, mark that spot, and use it like you would use the pin.  That 9" pin would end up having a 4.5" anti-pin, which is long-ish but very drillable.

And all that really does is turn the weight block upside down.

We put the pin above the bridge and the CG is below the thumb RH quadrant and a balance hole 2 in below and to the right of that. My span is 5 inches so i don't know if that helped at all but it scaled out fine and it rolls great. It clears the heads fine and picks up in the mids and moves to the pocket smooth and continous.

When we used to get the 9+" pins, we would draw a line from the pin through the CG to 13 1/2" and make that the new pin. Place that point where you would want the pin and go from there. And yes you are basically turning the core upside down.

Reverse the pin as stated above the ball will still react well with the new pin.. Ive done it with 5 or 6 balls and all have been great

I agree.  It also makes laying out the ball significantly easier and makes predicting the ball motion that much easier, too.
