ABSTRACT:
This invention is a pattern cutting assembly including a pattern guide member used in cooperation with a pattern and workpiece holding frame which, in turn, has a workpiece member mounted thereon and used in conjunction with a rotating blade, such as a router blade or a scroll saw blade, to cut a pre-determined accurate pattern within the workpiece member. The pattern cutting guide member includes a main circular support plate with a central opening in which a guide hub member is mounted and a clip connector assembly. The clip connector assembly includes a plurality of spaced clip members for anchoring and positioning in an upper support plate of a router table assembly. The pattern guide member can have the main circular support plate and the central guide hub member provided with a connected slot portion from an outer periphery of the main circular support plate which allows for a continuous blade, such as a jigsaw blade or a scroll saw blade, to be positioned centrally of the guide hub member. The pattern and workpiece holding frame holds a workpiece member and cooperates with the pattern guide member to achieve a pre-determined unique design within the workpiece member.
