An apparatus comprising:
- a fixture configured to attach to a support, wherein the fixture includes an inlet hole and an outlet hole and the support includes an inlet, an outlet, and a cavity, with the inlet and outlet aligned with the inlet hole and outlet hole, respectively, and the cavity configured to receive a vane;
- an adhesive inlet tube;
- an adhesive outlet tube;
- pressure control devices in communication with the adhesive inlet tube and the adhesive outlet tube and configured to cause an adhesive to flow between the vane and the support from an inlet to an outlet, and reverse the flow of adhesive from the outlet towards the inlet;
- and
- a seal surrounding an end of the support, the seal establishing a clearance region between the vane and the support to receive the adhesive, wherein:
- there is a gap along at least a portion of a perimeter between the vane and the support,
- the seal has a contour facing the gap, and
- the seal is configured to prevent adhesive leaving an end of the cavity and is configured to cause the adhesive to form a fillet shape due to the contour of the seal.
