  • Publication number: 20070135246
    Abstract: The present technology relates to laminated ball bats and a methodology for making the same. The disclosed technology provides for a laminated blank suitable for machining into a laminated bat having a generic bat shape (such as a bat consisting of a handle and a barrel where the handle has a smaller diameter than the barrel) that offers greater flexibility in changing the bat's weight distribution. Using lamination technology, various portions of a blank may be constructed having different densities (and associated weights) thereby decoupling such blank's length/weight properties. Such technology provides a method of positioning a bat's center of mass (CM) at various locations along the bat thereby changing the location of the bat's sweet spot zone center. Bats constructed in accordance with the disclosed technology may have a variety of pre-selected weight distributions while maintaining a particular bat shape and a particular overall bat weight.
