    • A two-piece ball bat comprising a hollow barrel attached to a handle by a combination of mechanical interference and a layer of rigid adhesive interposed between the interior surface of the barrel and the exterior surface of the handle at a tapered junction. The rigid adhesive layer prevents any direct contact between the barrel and handle thereby eliminating the need to provide any mating features thereon and reducing complexity and cost of manufacture. In an alternative embodiment, glass shafting beads are added to the rigid adhesive compound to ensure even distribution of the adhesive compound, align the barrel and handle and ensure separation prior to curing.
    • 一个两件式的球蝙蝠,包括通过机械干涉的组合连接到手柄的中空筒,并且在锥形接合处插入在筒的内表面和手柄的外表面之间的刚性粘合剂层。 刚性粘合剂层防止筒和手柄之间的任何直接接触,从而消除了在其上提供任何配合特征的需要,并降低制造的复杂性和成本。 在替代实施例中,将玻璃轴系珠粒加入到刚性粘合剂化合物中以确保粘合剂化合物的均匀分布,对准筒体和手柄并确保在固化之前分离。
