Machine tool jig

A jig for a machine tool as claimed in any preceding claim wherein the template aperture has an elongate slot shape with rounded ends.

A jig for a machine tool as claimed in any preceding claim, wherein the template board means is mounted to a frame of the jig so that it may move longitudinally fore or aft of the jig to assist in properly aligning the template aperture over the work-piece.

A jig for a machine tool as claimed in any preceding claim, wherein the securing means provided on the work-piece mounting board means are adjustably positionable laterally of the jig.

A jig for a machine tool as claimed in any preceding claim, wherein the work-piece mounting board means is mounted to a backing board means, which backing board means is pivotally mounted to the template board means, directly or indirectly, and where the work-piece mounting board may be moved laterally across the face of the backing board means to adjust the lateral alignment of the workpiece relative to the template aperture.

A jig for a machine tool used in joinery, such as a portable router or the like, and which is suited for forming joints having compound angles, the jig comprising:

• a work-piece mounting board means having means to releasably secure a work piece thereto;
• and
• a template board means overlying the mounting board means and against which the machine tool abuts, in use, and defining a template aperture for guiding the machine tool in a pre-defined path relative to the work-piece to machine the work-piece, the template board means and work piece mounting board means being movable in more than one plane relative to each other to selectively position the work-piece at chosen angles of tilt relative to the work piece and releasably fastenable at the selected position, so that a compound angle joint may be machined by moving the machine tool around the template aperture and without need to re-adjust the position of the work-piece.
