Milling is the process of machining flat, curved, or irregular surfaces by feeding the workpiece against a rotating cutter containing a number of cutting edges. The flexible ball joint allows the tail of the dog to move in a radius along the axis of the workpiece, making it particularly useful in the rapid milling of tapers. Holding

The Rough Surface Technology on Golf Clubs. The amount of spin you place on a golf ball directly affects the success or failure of a variety of shots. For example, you must impart just the right amount of side spin on the ball to hit a controlled fade or draw. When you're hitting an approach shot, you typically want as much backspin as possible on the ball -- particularly if you're hitting
