Abstract
A method for assembling a rotating machine and a blade attachment mechanism are provided. A first dovetail slot having a first axial length and a second dovetail slot having a second axial length are each formed in the attachment mechanism such that the second dovetail slot is radially outboard of the first dovetail slot. First axial length is greater than the second axial length and each slot is substantially parallel to an axial centerline of the rotating machine. A first dovetail lobe having a third axial length that is shorter than the first axial length and a second dovetail lobe having a fourth axial length, shorter than the first axial length and longer than the third axial length, are each formed in the attachment mechanism and positioned to correspond with first and second dovetail slot, respectively, such that the second dovetail lobe is radially outward from the first dovetail lobe.
