Claim:
1. A component comprising: a body; a first cooling passageway disposed within the body, the first cooling passageway including a first hole therein; and a core tie disposed in the first hole, such that the core tie occludes the first hole, the core tie comprising: a tie member having an axial length, and a substantially rectangular cross sectional area which varies along the axial length of the tie member, wherein a variation in the cross sectional area of the tie member positively secures a position of the core tie relative to the first hole, wherein the tie member includes: a first cross sectional area at each of a first end, a second end, and a point approximately midway along the axial length of the tie member, and a second cross sectional area at each of a point between the first end and the point approximately midway along the axial length of the tie member, and a point between the second end and the point approximately midway along the axial length of the tie member, wherein the first cross sectional area is greater than the second cross sectional area, and wherein the first cross sectional area is greater than a diameter of the first hole.
