ABSTRACT:
The jig of this invention holds a radial array of separate materials together so that they can be glued, welded, or otherwise secured together. The jig is then removed. A plurality of fingers are pivoted to a common support, and elastic means are used to urge the fingers together to tightly grip the radial array of materials to be held. The finger surfaces are angular to correspond to the angle of the materials to be held and for a cross shaped array of materials, the finger surfaces are at 90.degree. to each other. The fingers have shanks that project beyond the hinge or pivot point and these projecting shanks may be used to open up the fingers by manually grasping the projecting shanks and thereby overcoming the elastic means which normally urges the fingers together.
