What causes a ball to flare in the wrong direction?

I believe a full roller drill will flare towards the thumb, or counterclock-wise for a right hander.


charlest -- It depends.  Are you referring to a right handed full roller or 3/4 roller?  


3/4 roller.

The counterclock wise part is correct for either, but for a full roller this is away from, not toward the thumb hole.


Because he is already between the thumb and fingers.

Precision -- I don't think so.  Remember, the bowtie is beside and slightly below the thumb hole.  Mentally shift the grip so the bowtie is at a more normal position, beside the finger holes.  Now, the flare below the bowtie is away from the thumb hole and above the bowtie the flare is from left to right or clockwise.  But with the bowtie below the thumb hole, the flare rings move in the same direction as the flare rings above the finger holes in our "mentally shifted" view, clockwise and toward the finger holes.  --  JohnP

I double checked the the layout after Next Level PS' post, the ball is drilled to the spec in the drill sheet using the correct PAP 5" over and 0.25" up.  I'm a left handed high 3/4 roller, about 0.5" from the fingers and 0.25' from the thumb hole, maybe 15 degrees of tilt.  The pin is 1.5" from my PAP, 1.25" above midline, and 0.75" inward of the VAL.  Very close to the VAL, but not over.  

This is a second drill for this ball and that may be a factor in this problem.

Also, just to re-iterate, the ball is flaring over my thumb.

The bowtie is centered just to the right (i'm left handed remember) and below the finger holes, and the ball flares clockwise, causing it to roll over the thumb hole, instead of counter clockwise and away from the the thumbhole.  

I'm aware of cases of people taking thumb weight out to move a bowtie up to allow a ball to flare around the finger holes, so I'm supposing that taking out finger weight may allow me to move the bowtie down placing it closer to the thumb hole and allow the ball to flare away from the fingers and pivot around the thumb without rolling over it.

Just a wild guess:
If your track is 1/4" from thumb hole and 1/2" from finger hole, your PAP is a lot greater than 5" over, probably 6", and maybe slightly more.

Precision -- You're right, I missed the fact that the pin is past the track.  Just goes to show how easy it is to get mixed up on flare directions.  --  JohnP

^^ I was thinking the exact same thing.  I have a very high tilt(about 15-17 degrees) and I track WAY off the fingers and thumb.  4 1/4 right 3/16 down is my axis point.

And when you recheck your PAP, be SURE you are using the very first flare ring.  The best way is to use a non-flaring ball, such as a Columbia White Dot, Ebonite Maxim, etc. to locate the PAP (be sure to use your strike ball release), then confirm it by marking it with a piece of white tape.  When you throw it again the piece of tape should appear stationary.  If you mark a flaring ball with the white tape, it will appear stationary for only the first 10 - 15 feet of its travel.  You will have to have an observer watch it because by the time you pick it up in your vision it will have already started to flare.  --  JohnP

My bad, typing error, PAP is 6.0" and 0.25"

I'll double check anyhoo, I have a ball that has very visible track lines on it, I'll mark them in with a wax pencil and take a picture so you guys can verify I'm doing that right.

The tilt is something I've never really understood.  How do you measure that?

First you need to determine the diameter of your track.  See the instructions at the following link:

https://www.buddiesproshop.com/23/Finding+Track+Diameter.htm

Then, Axis Tilt = (13.5 - Track Diameter) * 6.67

Example:  Track Diameter = 11 1/4":    

          Axis Tilt = (13.5 - 11.25) * 6.67 = 15 degrees
