<p>The invention relates to a method of assembling a structure, particularly those structures requiring very tight tolerances. The structure may be assembled by positioning shim material (20) on at least part of a sub-structure (2), curing the shim material (20) in situ, machining the cured shim material (20) to a desired thickness, and then assembling outer layer parts (4, 8) to the sub-structure such that the shim material is situated between the sub-structure and the outer parts. The shim material may be machined to different thicknesses at different locations on the sub-structure, so that, when assembled, the outer layer parts together conform to a predetermined profile. This is especially advantageous in the manufacture of airframes, where the outer layer panels must provide a smooth surface to avoid unwanted aerodynamic effects.</p> |
