Claim 5:
6. A method for assembling the stator core of a generator, the method comprising the steps:
stacking a plurality of stator donuts to define a stator core 10; and
attaching the stator core 10 to a stator frame of a generator by mounting the plurality of stator donuts to a plurality of building bolts associated with the stator frame utilizing a plurality of wedge assemblies, the mounting comprising:
sliding each wedge assembly into a respective notch so that a first side of the upper wedge is positioned to abut a wall of the groove and a curved side of the lower wedge lies against the building bolt, and
tightening the tensioning bolt 115 of each wedge assembly 100 effective to secure the stator core 10 to the building bolt,

wherein each set of opposing wedges comprises:
an upper wedge including a first surface 102 configured to be positioned within the groove and a first opposing surface 104 including a threaded portion, and
a lower wedge including a curved surface 108 that conforms to the building bolt and a second opposing surface that mates to the first opposing surface.
