1. A tool holder support assembly, comprising:

  • a first support member having a dovetail projection protruding from a first support surface and extending lengthwise in a first direction, said dovetail projection including a pair of opposed sloped surfaces extended in said first direction and converging toward said first support surface to define, in part, a cross section of said dovetail projection;

    a second support member having a second support surface with a dovetail slot formed in said second support surface, said dovetail projection of said first support member being slidably engageable in said dovetail slot with said second support surface adjacent to said first support surface, a lateral opening in said second support member extending transversely to and intersecting said dovetail slot to expose a portion of one of said sloped surfaces of said dovetail projection when said first and second support members are slidably engaged;

    a wedge member inserted in said lateral opening and having a wedge surface movable translationally without rotation to make contact with said one exposed sloped surface of said dovetail projection, pressing said wedge surface against said one exposed sloped surface causing, by wedge action, said first support surface to press against said second support surface, whereby said first and second support members are releasibly fixed relative to each other; and

    driving means for translating said wedge surface without rotation to press against said one exposed sloped surface of said dovetail projection.
