Small Parts Clamp (Softer grip than pliers.) The jaws of the clamp are made from a short section of 1 1/4" dowel. The dowel is split down the center and then the two halves are reassembled with a bolt, a wing nut and a few washers that space the "jaws" apart. A wedge inserted at the back of the clamp forces the jaws together. Start by drilling the bolt hole through the dowel section and then tapering the jaw end with a sander. Cut the dowel and add the wedge.
