ABSTRACT:
A clamp for use in holding a wing panel stringer to a header on a wing panel jig includes a clamp base affixed to the header. A stringer locator, which has a pair of clamp-engaging surfaces, is mounted for rotational movement on the clamp base. The first clamp-engaging surface is oriented generally parallel to the rotational axis of the locator while the second surface is a locus of lines that are preferably generally perpendicular to the first surface and form a convexly arcuate second surface. A J-shaped clamping member is slidably and rotationally mounted in the clamp base. The terminus of the curved portion of the clamping member engages the exposed surface of a stringer to hold it tightly against the first and second clamp surfaces.
