Title: Fixture for drilling long holes in doors

Abstract: A door drilling fixture is provided for drilling a long straight hole in a door from the hinge edge of the door to a through aperture of the door adjacent the latch edge of the door. The hole is for passing wires from the hinge edge to a device such as an electric lock in the aperture. The fixture ensures that the hole will run parallel to a broad face of the door by clamping to the door face at the hinge edge and at the aperture. The fixture includes an elongate body with a planar, non-marring bearing surface for clamping tightly against the broad face of the door. A set of drill bushings aligned along a drill axis parallel to, and spaced apart a fixed distance from, the bearing surface is mounted at one end of the body. A clamp assembly for clamping to the hinge edge is attached to the fixture adjacent the drill bushings. A second clamp assembly attached to the other end of the body passes through the aperture. It is connected to the body by an elongate slot to adjust for the distance between the hinge edge and the aperture.
