What does an Oliving Machine Operator do?
Grinds olive-shaped contour to bearing surface of olive-jewel hole: Fits wire strung with jewels, and on which wire diamond dust is spread, in holding bow. Holds bow so that jewel is rotated between shaped rotating wheels of machine while rocking bow back and forth so that action of wire on rotating jewel will wear away sides of hole to olive shape. Repeats bowing operation on rest of jewels on string. Inspects jewels for shape of olive and measures hole size with graduated, tapered needle.
