4X2 drilling for a assymetrical core
« on: July 26, 2003, 06:56:07 AM »
Am I correct in saying that a 4x2 drilling with a symetrical core would have the cg 2" from my PAP and in an assymetrical core with the mb 2" from my PAP? The reason I ask this is I have always had symetrical cores and I am thinking of buying a ball with an assymetrical core and I want to make sure I have it drilled correctly for a 4x2 drilling with a ball that has a cg and a mb marking.

Thank you

As far as I'm concerned, a 4 x 2 is the pin 4" from your PAP and the CG 2" from your PAP, no matter if it's a symmetrical or asymmetrical core ball with a MB marking. =:^D

The MB is usually referenced as being near the VAL, near the track or, left or right of the Thumb hole. Near the VAL is considered very early rolling, near the track is very late rolling. Like most generalities, these are very vague and non-specific, to be redundant.

Rob, with the asymetrical balls you would use the MB as the second number, were the cg is just determines were you have to put a balance hole, if one is needed. As far as the layout you have described,if you don't already know you axis tilt, not you axis rotation or your pap, find that out. That plays a big part on what type of layouts suit your game. If you have low axis tilt, about 10 degrees and under, the layout you want will not work, the ball will burn up on you. With higher axis tilt, 23 degrees and higher, then something like that would work. So go to a certified pro shop and find that out and if you need help finding one in your area just feel free to contact me.

I agree with T-GOD and charlest: a 4x2 is a 4x2. A 4x2 on an asymmetrical ball will put the mb at or near your VAL.

A coordinate drill, regardless of ball, is still pin to pap, cg to pap, however when the mb is marked or on an asymmetrical ball, you focus on the END placement of the MB.  You still use the cg for the second coordinate mark, but focus on the mb end location.

So on the asymmetrical ball it would look like this:

...O.O.pin

.............cg---PAP

....O...........mb

On the Symetrical ball, there wouldn't be the mb mark.

To the other guys that have replied to this topic. On the asymetrical balls, the cg is ignored. You all know that sometimes the pin, cg, and MB marking are not in line, so if you were to do a 4x2 using the cg on an asymetrical ball and the cg on the undrilled ball is to the right of the pin, for a right handed bowler, that layout will be incorrect. Thats why you ignore the cg on the asymetrical balls. That was the big thing that Del Warren and Mo Pinel have been going across the country with this year. They came up with a chart that helps the driller on finding your axis tilt and how to use layouts that fit your game.

Already has been said above......the fact still remains......it doesn't matter what kind of ball it is...a coordinate layout is measured pin to pap x cg to pap.  This can still give you a generic look at where the MB would be placed once drilled.....but yes, in the asymmetric(or MB marked ball), the MB is the determining factor

Obviously T-God is afraid of change. Mo was the first to bring out the asymetrical ball and everyone thought he was crazy and look now everyone has one. So if you want to bash Mo and Del go ahead, but unfortunatly for you they are at the forefront of the new technology, and you can continue to throw the same stuff that your friends throw cause you bowl on china and anything will work.
