Abstract
According to the present invention, a method is provided for making joints having angles other than right angles. Also, according to the invention, thickness of wood to be cut and/or size of the router bits used with a particular setup of template and fence can be changed simply by use of shims, without need for readjusting the fence or screws connecting the templates to their corresponding fences. This adjustability now includes, as a novel feature, the ability to cut dovetail joints using pin boards in stock thicker than the length of a dovetail bit without having to use a fence in which a rabbeted shim is substituted for a straight shim. Additionally, a method of cutting box joints using a combination of a dovetail template and a pin router bit has been found.
