Abstract: A part-holding assembly for use with a vise having a pair of jaws movable relative to one another. The part-holding assembly has a plurality of elongated, parallel blocks that are supported for relative movement on a pair of elongated parallel guide rods. A first one of the blocks may be removably positioned adjacent to the stationary jaw of the vise and has first and second spaced-apart cavities formed therein. A second one of the blocks may be removably positioned adjacent to the moveable jaw of the vise and has a first generally horizontally-extending through-hole aligned with the first cavity of the first block and a second generally horizontally-extending through-hole aligned with the second cavity of the first block.
