The coverstock is typically made from a reactive resin material that is formulated to provide a specific level of hook potential, or the ball’s ability to change direction as it moves down the lane. Different types of coverstock materials can be used to create balls with varying levels of hook potential, from small, subtle arcs to large, dramatic hooks.
The coverstock is also responsible for the ball’s overall durability and resistance to wear and tear. A good coverstock will be able to withstand the rigors of repeated use, maintaining its texture and integrity even after many games. By carefully selecting and applying the coverstock, manufacturers can help to ensure that their bowling balls provide consistent and predictable performance, even over extended periods of use. Additionally, the coverstock can be formulated to provide specific benefits, such as increased traction or reduced oil absorption, which can help to enhance the ball’s overall performance and give bowlers a competitive edge.
How are bowling balls weighted and balanced?
Bowling balls are weighted and balanced through a combination of core design and material selection. The core is designed to provide the ball with its overall weight, which is typically between 6 and 16 pounds. The core is also designed to provide the ball with its weight block, which is the heavy mass inside the ball that helps to create the ball’s rotation and movement on the lane. The weight block is carefully positioned within the core to provide the ball with the desired balance and stability.
The ball is then inspected and tested to ensure that it meets the manufacturer’s specifications for weight and balance. This includes checking the ball’s overall weight, as well as its balance and stability. The ball is also tested for its hook potential and overall performance, to ensure that it meets the manufacturer’s standards.
