Abstract: According to one aspect of the invention, a method is provided for modifying an airfoil shroud located at a tip of an airfoil of a airfoil, the airfoil shroud having a first end edge, a second end edge, a leading edge and a trailing edge. The method includes locating a reference location in the first end edge of the airfoil shroud, the reference location being proximate a seal rail extending circumferentially from the substantially horizontal surface and forming a relief cut in the airfoil shroud to remove the reference location, wherein a modifying of the airfoil shroud is complete following forming of the relief cut.

Abstract: A method and system for sealing a gap between a bucket dovetail and a rotor is provided. The dovetail seal includes a first end portion extending from a first extent of the first end portion a predetermined distance along a length of the dovetail seal, a second end portion extending from a first extent of the second end portion a predetermined distance along a length of the dovetail seal towards the first end portion, and a body extending between the first and second end portions. The body includes a U-shaped bend complementary to a sealing groove in a dovetail of a turbine blade. The first end portion includes a converging flared cross-section from the first extent of the first end portion toward the second end portion and the second end portion includes a converging flared cross-section from the first extent of the second end portion toward the first end portion.
