Abstract
A spider for a Hooke's joint typically includes a center piece and four pins radiating therefrom. The pins are all located in a plane which intersects the rotation axis of the spider. Between adjacent pins, the center piece has a transition section, which is machined to define a concave fillet. In the preferred form, the fillet is shaped to define an arched, toric outer surface, and particularly as viewed along a longitudinal cross section along the rotation axis of the center piece, the outer surface comprises two partially cylindrical fillets symmetrically located at opposite sides of the plane through which the axes of the pin pass. These two fillets are machined by a tool that moves longitudinally along a path parallel to the plane of the pin axes for machining and the tool is swung around a swivel axis parallel to the plane of the pin axis for forming the fillets symmetrically of the plane of the pin axis.
