A rugged sturdy workpiece positioning mechanism that effectively and efficiently positions and holds at least two workpieces for further operations is provided. The mechanism includes a main support which is slidably connected to a first workpiece and a housing assembly which is affixed to the main support and extends above and engages the second workpiece. The housing assembly includes two side plates, a cam with a handle rotatably attached to the sideplates, a ratchet to lock the cam into a fixed position and a load bearing surface actuated by the cam and slidably received between the side plates. The edge of the cam abuts the load bearing member. When the cam is rotated in a predetermined direction, the distance between its axis of rotation and the load bearing member increases driving the load bearing member downward. The load bearing surface engages the workpiece and forces the second workpiece into a desired position relative to the first workpiece. Once the joining operation is completed, the mechanism is slidably detached from the workpieces.

A mechanism for positioning at least a first and a second workpiece such that said workpieces are in abutment, said mechanism comprising: a support structure which is attachable to said first workpiece and firmly abuts said first workpiece, said support structure including a first portion which extends over said second workpiece when said mechanism is employed, said first portion being comprised of a first pair of spaced side plates, a cam rotatably attached to said first pair of side plates, a load bearing member which is designed to engage said second workpiece and is slidably engaged by and between said first pair of side plates, said cam abutting said load bearing member, wherein the rotation of said cam slides said load bearing member relative to said support structure, wherein said cam and said load bearing member are designed and arranged such that when said cam rotates in a predetermined direction, the distance between the axis of rotation of the cam and the surface of the load bearing member which engages the second workpiece increases and said second workpiece is pushed by said load bearing member in the direction the load bearing member is moving a distance equal to the aforesaid increase in distance, said load bearing member is comprised of a bottom edge member and a pair of second side plates extending above said bottom edge member, said second pair of said plates interfacing with said first pair of side plates, wherein said cam is located at least in part between said second pair of side plates.
