Abstract
A guide system for cutting return bends directly into the underlayment panels of a radiant floor heating system is provided that eliminates the need for the installation of separate return panels. The guide system includes a guide panel having a guide rail on its bottom surface and a pivoting guide on its top surface. The pivoting guide is pivotally movable through a 180-degree arc relative to the guide panel and is configured to receive a router with a plunge or dovetail bit installed therein. In this manner, the router is pivotably movable through a controlled 180-degree semi-circular arc from a point that is aligned with a groove in which the guide rail is installed to a groove in an adjacent underlayment panel allowing the user to pivot the router to cut a return bend into the underlayment in the desired location.
