A gripping surface includes a plurality of projections extending away from the gripping surface and a plurality of voids between and defined by the projections. The gripping surface may be disposed on a support surface, such as a deck of a skateboard or a deck of a balance board. The projections may be formed by cutting the support surface with a router, such as a computer numerical control router. The projections may each comprise three or more angles surfaces, whereby angled surfaces of proximal projections are positioned at mirror angles of one another.

Disclosed herein are various forms of hybrid baseball bats comprising a wood shell having a radial wall and an outer radial surface profile defining a baseball bat. The wood shell having a central core with a central surface thereon extending from a distal end of the bat. The central surface being profiled with a taper that in some embodiments extends entirely through to the proximal end. A fibrous construct is housed in the central core and infiltrated with an epoxy resin. In some forms, the fibrous construct is in the form of a sleeve. Disclosed are various manufacturing techniques for manufacturing hybrid baseball bats including a low pressure bladder method, a high pressure bladder method, and a centrifugal force method.

A process for encapsulating a bowling pin includes placing a pin in a mold; injecting a molten plastic material into the mold to encapsulate the pin; and cooling the mold to produce a finished bowling pin wherein. The plastic material includes 80% to 60% of nylon and 20% to 40% of ion resin. Preferably, the ion resin is zinc ion resin.

A method for fabricating weighted stabilized wood golf club heads allows for fabrication of a golf club head having enhanced control of balance, mass, center of gravity, and moment of inertia during operation of the golf club. The method includes selecting stabilized wood having a knotted and crossed grain composition and then designing a borehole pattern of boreholes based on the density and shape of the stabilized wood. The borehole pattern may be designed through a software or an algorithm to achieve efficient operation of the golf club head; and especially when swinging the golf club. The method also includes cutting a cross section of the stabilized wood, such as cutting in half. The method further comprises drilling boreholes through the cut sections of the stabilized wood, based on the borehole pattern. The cut sections of stabilized wood are clamped and adhered together. The method includes attaching a shaft and grips for operation of the golf club.

The present invention relates to a method and a system for manufacturing a board body (10), such as a skateboard, from a blank (20) having an indefinite shape. The blank (20) with the indefinite shape is collected by a handling robot (50). The shape of the blank (20) is scanned in three dimensions by means of a vision system (47) and a virtual image of said blank (20) is stored in a memory and used to calculate a three dimensional cutting path for milling the blank (20) into said board body (10).
