<p>A mortiser device and method for applying a mortise or offset in the edge of a hollow metal door where a dead bolt or other latch is to be installed. The device comprises a die block adapted to be positioned inside of the door edge at a point adjacent where a mortise is to be formed in the door edge, a cavity in the die block, a mortising block operatively connected to the die block by a pressure application device, whereby the mortising block is disposed on the outer side of the door edge adjacent the die block and a portion of the door edge extends between the die block and the mortising block. The pressure application device extends between the die block and the mortising block through the aperture in the door edge, and the pressure application device is adapted to press the mortising block and the portion of the door edge extending between the die block and the mortising block into the cavity in the die block to form an offset in the door edge. The method of applying a mortise to the edge panel of a hollow-door-having two spaced apart parallel panels adjacent the edge panel, the hollow door also comprising an opening for location of an entry lockset comprises the steps of forming a first hole in the door edge at the location where the mortise is to be formed; forming second and third holes in the two spaced apart parallel panels adjacent the first hole; removing the entry lockset from the door; inserting a die block having a cavity in one face thereof through the opening from which the entry lockset was removed; positioning the die block in the door behind the first hole whereby the door edge adjacent the first hole is positioned over the cavity in the die block; inserting a pressure application device through the first hole and attaching the pressure application device to the die block, the pressure application device including a mortising block extending along the portion of the door edge where the mortise is to be applied; and applying pressure to the mortising block by means of the pressure application device whereby the mortising block and the portion of the door edge extending along the mortising block is pressed into the cavity of the die block, whereby an offset is formed in the door edge.</p> |
