Delta 1 question and asymmetrical question
« on: November 27, 2005, 10:51:25 AM »
Something that i'm confused about with asymmetrical balls is this:

I thought that if I were to place the pin above the finger line that the ball would have more backend than if I placed the pin below the finger line?  I bought a Delta 1 and had to drill it with the pin below the finger because it had a 2" pin out.  This was the only ball he had and I couldn't wait for him to order one because I wanted it right then.  Well this ball has a huge backend.  Not flippy but a real strong arc.  The backend is not just huge but the continuation is just plain SICK!  Now if I buy another one( which I will) and order it with a 3"- 4" pin out and place the pin above the ring or bridge will this ball have even more backend?  I just can't imagine a ball having more backend than the one I have drilled with the pin below the ring.

Another point is my Delta 1 not only has the pin below the ring but the MB is below and about 2.5" right of the thumb.  If I buy one and place the pin above the ring and the MB 1" right of the thumb will this ball backend even more?  Or is this just to close of a drill layout too notice a difference?

That MB placement is very close to the flip/strong position and the ball is naturally strong in the backend.
Do you know what the actual pin to PAP and MB to PAP measurements are on the one you have, if you do I can figure out what the degree of the layout is and that may help explain why it is so strong in the backend.

correct if the pin to PAP distance is the same the ball with the pin below the fingers will get into a slightly earlier roll releasing energy earlier.

Yes The pin above the finger will make the core taller storing more energy for the backend.

that all depends on the distance from the MB to your PAP. But to help create seperation between the two balls I would polish the one with the pin above your fingers.

Hey chi,

Yes, a pin out or above will go longer and have more backend in comparison to a pin in/under ball assuming the mb placements are the same distance on the balls also.  Remember (for asymmetrical balls), mass bias controls reaction "shape" so if you have a pin up but place a mb 6-7 inches away from pap, you're killing the reaction bud and it won't be angular by any means.  The same would happen if you placed mass bias 2 inches or less from pap, this would cause it to roll extremely early and not be "angular" either.

I like the idea of keeping a similar layout (measure pin and mb to pap to get accurate and consistent reactions) and then polish one.  That should give you a similar look but for different amounts of oil.  Just a thought bud...

I love the backend reaction I get out of this ball.  I'm not complaining about it.  I just have never seen a ball backend like this.  My angular has a huge backemd as does my reactive but this ball is more.  I love the reaction I get from this ball.

What i'm going to do is get a ball with the pin about 3"-4" pin out and drill this one with the MB in the same location(distance to pap) then just polish it.

Thanks for the replies.

Oh I almost forgot.  If you drill the pin above the finger line does a person have to drill an x-hole to make the core taller?  I wouldn't think so but this is what Tracks drill layout suggest's

Tracks drill sheets are always accurate,..I'd pay attention to them.

Rick is right.....HOWEVER.....if you want "angular" go according to Tracks drill sheets for 'angular' ....probably 3 3/8 to 4" from pap for the pin and about 5" from pap for MB

Thanks Jeff.  I'm just trying to learn.  I love the reaction I get out of the Delta 1 I have.  I'm going to buy another one with a longer pin out so I can drill it with the pin above the ring and place the MB in the same spot my current Delta 1 has.  Then I will bring the DElta 1 That I have now back to the 900 grit box finish because I have magic shine on  it now.

Great ball.  I won money with it yesterday.  First time used in league.
