Claim 10:
11. A wedge assembly for securing a stator core of a generator to a building bolt during a stator core stacking process, comprising:
a set of opposing wedges configured to slide into a notch of a stator core 10 and provide a locking force between the building bolt and the stator core, comprising:
an upper wedge including a first surface and a first opposing surface including a threaded portion, and
a lower wedge including a curved surface that conforms to the building bolt and a second opposing surface that mates to the first opposing surface,
wherein the first opposing surface of the upper wedge and the second opposing surface of the lower wedge each include a repeating ramped profile that interlock when mated; and

a tensioning bolt arranged in the upper wedge and the lower wedge to receive a torque effective to drive the set of opposing wedges in opposite directions making the wedge assembly 100 thicker.
