ABSTRACT:
A machine for removing excess filling material and refinishing the surface to a true sphere after one or more of the finger holes in a bowling ball have been filled in. The machine frame carries a motor-driven sanding disc and a pair of ways. Slidable on the ways is a carriage, which may be moved by means of a lead screw rotated by a hand wheel with a calibrated dial. The bowling ball to be refinished is supported rollably on a number of ball casters or the like which are mounted on the carriage. The ball may be rotated or rolled by hand about any axis, but is constrained against motion in translation except by translation of the carriage itself. In use, the carriage is advanced until the ball just touches tangentially the rotating sanding disc. The ball is then rolled manually to present its surface to the disc. The carriage may then be advanced 0.05 mm or so and the process repeated. Dust from the operation is collected in a novel housing by a combination of centrifugal and suction means.
