Abstract
A method for making dovetail joints connecting a pin board having a curved cross-section to a dovetail board having a curved edge. The method includes a method of cutting dovetails in the dovetail board by positioning a dovetail template defining a dovetail slot tangential to the curved edge of the dovetail board with the dovetail slot centered over a point on the curved edge which is closest to the template. The dovetail is cut by means of a router with a dovetail bit, and the procedure is repeated for all points on the curved edge at which a dovetail is desired. The method also includes a method of cutting pins on a pin board by positioning a pin template having a tapered router guide normal to a point on an arched edge of the pin board. The pin is cut by means of a router with a straight bit, and the procedure is repeated for all points on the arched edge at which a pin is desired. Modified dovetail and pin templates for use with the method for making curved dovetail joints are also disclosed.
