Positioner/Holder. A fine concept and pretty successful execution. Weighted bases hold fully adjustable clips and lenses for delicate hands-free work. The Helping Hand has a 2" high base connected to (2) alligator clips via (3) universal joints and a 4-1/2" sliding beam, and to a 2-1/2" dia roughly 2X or 3X magnifier via another universal joint on the sliding beam. The Helping Hand w/Solder adds a holder for your soldering iron, plus a hole and thumbscrew in the base to firmly position it. The larger Work Stand has a 3-1/2" x 4-3/4" stand with a 2-3/4" square x 3/8" deep reservoir to hold small parts, an L-shaped sliding beam with (2) alligator clips, and another L-shaped beam with a 3-1/2" lens, about 4X magnification. Joints adjust every which way. The set screws can all be hand-tightened, but we suggest a small pliers to secure the hefty 4X lens. Think of the clips as extra hands to hold wires, components, beads, what-have-you while you perform some operation on them with your own two hands. Or think about any one of them as an ideal name tag holder at a robotics convention.
