DUAL ANGLE LAYOUT TECHNIQUE™ - Layout Method (Part Three)

Now draw the VAL using the scale of the Pro Sect® to complete the third and final component of the DUAL ANGLE LAYOUT TECHNIQUE™.

 

As with all accurate drilling techniques, measure back to the center of the grip using the vertical and horizontal components of the bowler's axis coordinates to find the center of the bowler's grip. After drawing the centerline of the grip, perpendicular to the midline, the ball driller can now drill the ball.

Wow, don't pictures help? In summary, the DUAL ANGLE LAYOUT TECHNIQUE™ is composed of three parts: the drilling angle, the Pin to PAP distance and the angle to the VAL. Ultimately, the success of this system depends on the ability of the ball driller to make accurate choices for all three!

***The effective use of DUAL ANGLE Layouts


The beauty of the DUAL ANGLE LAYOUT TECHNIQUE™ is that it allows the ball driller to keep the desired ball reaction in perspective when matching the bowler to the lane condition. By making a good decision in choosing the Pin to PAP distance, the ball driller can determine the amount of friction between the ball and the lane by controlling the track flare of the drilled ball. Once the amount of friction is determined, the ball driller can shape the breakpoint by choosing the drilling angle and the angle to the VAL. Adding the drilling angle and the angle to the VAL together will allow the ball driller to choose how quickly the ball will transition from skid to hook to roll.

 

If the two angles add up to 30°, the ball will transition as quickly as possible. If the two angles add up to 160°, the ball will transition as slow as possible. Keep the sum of the two angles between 30° and 160° to create effective ball reactions while still allowing the ball to maintain hitting power. Yet the drilling angle must still be kept between 10°and 90° and the angle to the VAL between 20° and approximately 70° (depending on the bowler's track).
