ABSTRACT:
The present invention relates to a router trammel including several attachments and features which allow the user to operate a router to accurately and reproducibly create different designs and cuts on a piece of wood. The inventive device includes an adjustable miter gauge including a protractor device about which guide means may be swung to allow angular adjustments. Additional features include the use of a pivotable fence to guide long vertical cuts, a threaded rod designed to be used for additional clamping for rabbet cuts and mitre cuts, as well as an elongated beam slidably mounted to support means incorporated in the mitre gauge, which beam is removably attachable to a router device.
