Guide bearing stop for use in a template-guided system for routers, and more particularly to a device, system, and method, for facilitating efficient, easily repeatable, highly accurate router mortise cuts on workpieces using a pantograph-type router system. The guide bearing stop may be used with a readily adjustable template holder for holding a guide bearing stop to direct the mortise cut in a very exact manner, which is also readily adjustable and easily positioned and centered on the template holder. The guide bearing stop when used in conjunction with the router system allows for the rapid centering and rapid reproduction of varying sizes of exactly-sized and exactly-shaped mortise cuts across a variety of different workpieces.

The present invention provides a jig for fabricating a concave-convex structure. The jig for fabricating a concave-convex structure is coupled to a multipurpose woodworking device including a woodworking work table for performing a plurality of operations for forming a concave-convex structure and a router mounted on the woodworking work table to perform the operations for forming a concave-convex structure, using a plurality of end mills. Furthermore, the jig for fabricating a concave-convex structure includes at least one of a wood piece support jig supporting or fixing a wood piece to be fabricated, a shaping guide jig allowing for forming shapes corresponding to the operations for forming a concave-convex structure, and a stopper jig maintaining X-axial movement of the router by intervals corresponding to the operations for forming a concave-convex structure. Accordingly, it is possible to easily fabricate circular, round, rectangular, dovetailed, and gallery-shaped grooves and joints.

A routing jig for enabling location of router guides prior to routing a feature into a workpiece includes a transparent or semi-transparent base component having longitudinal sides, a lower surface and an upper surface. The routing jig also includes retaining structure such as side bars and screws. The base component and the retaining structure together define a nominal width of the routing jig in a transverse direction. A plurality of shims are selectively and removably securable to the longitudinal sides of the base component by the retaining structure, thereby to increase the nominal width of the routing jig.

The present invention provides, in one aspect, a router including a motor unit and a base configured to selectively receive the motor unit to support the router on a work piece surface. The motor unit includes a motor and a spindle configured to output a torque supplied by the motor. The base includes an input shaft configured to selectively couple to the spindle, an output shaft laterally offset from the input shaft, and a belt. The input shaft includes a first pulley and the output shaft includes a second pulley and a tool holder. The belt wraps around the first and second pulleys to rotationally couple the input shaft to the output shaft. When the motor unit is received into the base, the spindle couples to the input shaft.

A sled for guiding a common hand router to cut a precision planar surface on a workpiece has plywood frame rails spaced by cradles supporting the workpiece between the frame rails. Base rails riding on the upper edge surfaces of the plywood frame rails are sequentially incrementally advanced at intervals along the frame rails in an X-axis direction by a linear ratchet assembly. A router is reciprocated in Y-axis directions during the intervals between the sequential incremental advances of the base rails, cutting a precision planar surface on the workpiece. The router is adapted to adjust the Z-axis elevation of the router cutter. The sled may be manually operated or automated.

A guide apparatus for guiding a woodworking router relative a workpiece, comprising: a base for engaging with a workpiece or worktable carrying the workpiece; a guide frame coupled to the base and having at least one guide defining a linear guide path; a router housing slidably engaged with the guide for movement along the guide path relative the guide frame in an engaging direction towards the base and a disengaging direction away from the base, the router housing being configured to receive a woodworking router so that, in use, a router bit of the router extends from the router housing towards the base; and an actuation mechanism having a pivotable handle for receiving an input force from an operator to move housing along the guide path. The actuation mechanism is configured so that an input force is required to raise the housing and the router received therein against gravity.
