ABSTRACT:
An assembly jig for making wing spars is adjustable in a manner so that it can be used to produce virtually any size of spar. The jig includes a plurality of vertical posts, each of which has upper and lower clamping mechanisms that are vertically adjustable. The upper mechanism holds the upper spar chord to the spar's web and the lower mechanism similarly holds the spar's lower chord. Adjustment of the clamping mechanisms relative to each other accommodates a variation in web width corresponding to different stations along the length of the spar, or alternatively, different spar designs. Each post is further adjustable in a transverse direction in order to construc spars which are not linear from end to end.
