Abstract: Wire, or other material, is wrapped around a shaft as the shaft turns, producing a coil. After being slid off the end of the shaft, the coil can be re-coiled by repeating the process. By shaping the twice-coiled material, a variety of pleasing jewelry beads may be formed. A variety of jigs useful for performing process are disclosed. One jig is easily and inexpensively manufactured from a unitary length of small rod, bent to provide (a) a wrapping shaft, (b) a feature for securing a free wire end; and (c) an actuator handle. The novel principles can be implemented in many different embodiments.

Abstract: An exemplary apparatus is a jig including a chuck having a plurality of radially movable members for controllably gripping a member inserted in an axial bore extending therethrough. The chuck is mounted on a hollow tube whose axis is collinear with the bore of the chuck. This jig is used by first positioning a first elongated member (e.g. a first, or "inner" wire) in the axial bore of the chuck, and tightening the radially movable members thereon. The distal end of a second elongated member (e.g. a second, or "outer" wire) is secured in a fixed relationship with the chuck, so that the distal end turns with the chuck. The chuck is then rotated so as to rotate the first, inner wire. As this inner wire is rotated, the operator trains the second wire thereagainst, thereby yielding a length of coil with the inner wire extending therethrough.
