Abstract: A portable router for cutting slots in a cabinet door to receive wings of hinges includes a router motor and spindle mounted on a slide which moves back and forth on a frame. The latter rests on the door when cutting each slot and is located on the door by a selected one of two guides. The latter are disposed on opposite sides of the spindle and project down beneath the frame into an active position but may be pushed up to a retracted or inactive position. One guide is adapted to engage one end of the door and its spacing from the spindle is correlated with the desired spacing between that end and the adjacent slot. Similarly, the other guide is adapted to engage the other end of the door and locates the spindle for cutting the slot near that end. As the frame is lowered onto the door, the latter engages the inactive guide which thereby is pushed up to its retracted position and the guide drops by gravity to its active position as the router is lifted off the door.
