A method of obtaining a copy key includes the steps of acquiring characteristic parameters of the original using a detection system; identifying operating instructions to reproduce the characteristic parameters so acquired; requiring authorization to load into a duplicating machine and/or use by a duplicating machine the operating instructions for creating the copy key; only if the authorization is given, loading the operating instructions into the duplicating machine and/or making the operating instruction available for use by the duplicating machine; controlling the duplicating machine so as to obtain, on the basis of the operating instructions previously loaded and/or made available, at least one copy key; and after the at least one copy key is obtained, removing the operating instructions from the duplicating machine.

A kit for making a sign utilizing a router includes a plurality of interlocking templates that can be utilized to form the letters for a sign. The kit includes two or more templates that are positioned in the same location on a board in a sequence to form a single letter, number or symbol with an island with an uninterrupted perimeter. The kit also includes a guide bushing that is secured to the router bit to prevent the router bit from gouging into the templates.

An example tool includes a body configured to be secured to a substrate, and a template on or in the body. The template defines at least one of a nominal or a maximum material-removal region. An example assembly includes a substrate defining an aperture, and the tool, including the body secured to the substrate. The nominal material-removal region or the maximum material-removal region are substantially aligned with a respective nominal periphery or a maximum periphery of the aperture. An example technique for machining the substrate includes securing the body of the tool to the substrate. The technique includes substantially aligning the nominal or the maximum material-removal region defined by the template with the respective nominal or the respective maximum periphery of the aperture. The technique includes removing material from the substrate only from a region defined by the nominal or maximum material-removal region.

Tapered, stepped, or non-tapered router guide templates, and optionally combined template holder system, each template comprising: a base portion, a top portion, at least one of an exterior surface interconnecting the base portion and the top portion along an outer periphery of the template and an interior surface interconnecting the base portion and the top portion along an inner periphery of the template, wherein optionally one of the exterior surface and the interior surface may be continuously tapered between the base portion and the top portion, or stepped, and wherein the base portion is adapted for removable and adjustable interconnection with the template holder system.

Provided is a router guide that comprises: a guide part that has a first through-hole and a guide surface that guides a cutting tool attachment part of a router device along the first through-hole; a maintaining part that maintains the position of the guide surface; and a positioning part that positions the guide part. The guide surface is formed such that, in a state where the maintaining part is in contact with a surface of a composite material, the distance from the surface becomes smaller as the guide surface approaches a second through-hole. The guide part is formed so as to be elastically deformable. In a case where the guide part is caused to elastically deform along the surface shape of the composite material, the maintaining part maintains the position of the guide surface with respect to the surface at a position that corresponds to the surface shape.
