Abstract
A method of constructing a mandrel generally complementary to a spar cavity of a spar includes connecting a first component and a second component to form a central space there between and inserting a center component within the central space such that the center component retains the first component and second component in a desired position forming an outer surface of the mandrel which corresponds to an inner surface of the spar cavity.

A method of constructing a mandrel including a plurality of components, the mandrel being substantially complementary to a spar cavity of a spar, comprising:
- connecting a first component and a second component to form a central space there between;
- and
- inserting a center component within the central space such that the center component retains the first component and second component in a desired position forming an outer surface of the mandrel which corresponds to an inner surface of the spar cavity,
- the first component having an exterior surface configured to form an interior leading edge of the spar or an interior trailing edge of the spar, and the second component having an exterior surface configured to form a portion of a lower interior surface of the spar or a portion of an upper interior surface of the spar, and the center component comprising a first end and a first protrusion, the first end and the first protrusion respectively configured to be received by the first component and the second component.
