Abstract: A worktop jig comprising a jig frame, wherein the jig frame comprises a pair of opposed end members and a pair of opposed side members; the opposed end members and the opposed side members together define a rectangular aperture within the jig frame; the opposed end members and the opposed side members each define an upwardly facing surface and the upwardly facing surfaces are arranged to lie in a common plane; and each of the opposed side members defines a downwardly facing surface, wherein each side member downwardly facing surface carries an angled elongate base element, whereby when the angled base elements of the worktop jig are located on a planar substrate, the common plane of the jig frame is angled with respect to the plane of the substrate

Abstract: A jig for profiling the end of an elongate workpiece, especially a coping or crown molding section, comprises a support for a sample to be copied, and for a profiling comb to be pushed against the sample to define a cam surface. A cutting tool can be mounted to follow a path defined by the cam surface, to cut the workpiece end to match the shape of the cam surface. The profiling comb is movable between a first position facing the sample support to form a profile and a second position in which the profile can contact the cam follower on the movable mounting. In its second position the comb extends at an acute angle to the longitudinal direction of the workpiece support, which is configured to support the workpiece at an acute angle about its longitudinal axis corresponding to the angle at which the comb is fixed.

Abstract: A router jig for profiling the end of an elongate workpiece, and in particular a coping or crown moulding section, comprises a support for a sample whose profile is to be copied, and for a profiling comb in the form of an array of parallel plates held in contact with one another by retaining means such as rods extending between a pair of support blocks, each said plate being individually and reversibly slidable in one direction relative to the others and having a contact surface at one end thereof whereby the contact surfaces of adjacent plates can pushed against a sample in the support to define a cam surface corresponding to the profile to be copied and a movable mounting on which a cutting tool can be mounted to move and follow a path defined by the cam surface, by means of a cam follower pin or the like, to match the shape of the cam surface. Means are provided for locking the plates of the profiling comb against said sliding movement.
