What are some bowling ball drilling layouts?


Quick Answer

The arcing layout, the early rolling layout and the flip layout are examples of basic bowling ball drilling layouts. BowlingBallGalaxy.com recommends the arcing layout for the typical bowler. When the ball is drilled, the pin is placed under the ring finger. The center of gravity is in line with the pin, angling toward the thumb, on a symmetrical bowling ball. On asymmetrical balls, the side with greater mass sits under the thumb and in line with the pin.

With the early rolling layout, the layout pin is under the ring finger. The ball's center of gravity is offset by 35 to 65 degrees, depending on how much early roll the player wants. The early rolling layout is used if the lane is oily, and it is generally used on reactive resin balls.

The flip layout is used in very dry conditions. The pin is directly over the center of gravity when the flip layout is used. A higher pin means that the ball moves further down the lane before it flips.

The pin shows where the top of the ball's core is sitting. It helps manufacturers to ensure the ball is perfectly spherical. The ball's track is the rings of oil that appear when the ball rolls down the lane. It indicates where the ball touched the lane. Ball drillers use the track to calculate the positive axis point and determine where the holes should go in relation to the pin and the center of gravity.
