  • Publication number: 20100212132
    Abstract: A kit comprises an expandable connector assembly and a router jig clamp assembly (41) to hold a workpiece comprises a router guide plate (42) having a router tool opening (43), a workpiece guide plate (44) having (45) guides (45 and 46) so that opposite mitres may be cut using the guides (45 and 46). The clamp (41) may be mounted on a bench adjacent a bench router so that upon alignment of a workpiece in position adjacent to opening (43) the press may be used to form the slot in the workpiece. The assembly has a clamp (47) comprising a handle (48), cams (49 and 50), a clamp bar (51) and spring mountings (52) at opposite ends. This enables a workpiece to be clamped when the handle (48) is pulled down to a position running generally parallel to the guide (44). Thus a workpiece is slid along one of the (45) guides into alignment with the slot (43) and then the clamp is applied to hold that piece in position for the slot cutting process.
