A drilling template for carving into the lateral edge or the jamb of a door, a slot shaped and dimensioned to receive either a lock and its mounting plate or its strikeplate has a series of drill bit bores at regular spaced-apart intervals along a central line, a pair of lateral legs, and mounting holes corresponding to those of the lock or strikeplate. A drill is used to rout the lock blade slot through the drill bit bores. Guides in either side of the bores prevent lateral movement of the bit, but allow slight longitudinal swing to remove material that may remain between holes. The height of the guides may be varied along the length of the template to guide the routing for a slot of more uniform depth. Lateral spacers are provided to align the template against the angled part of the door jamb. A specialized routing drill bit is provided for drilling the strikeplate or lock channel. The bit has central pilot shaft for tracking within the lock blade slot and a removable circular toothed disk. An oblong countersink bit-guiding insert is provided which creates strikeplate or lock mounting plate channels having straighter sidewalls.

Mortise drilling apparatus and method

A drilling template for carving into the lateral edge or the jamb of a door, a cavity shaped and dimensioned to receive either a flanged lock or its strikeplate has a series of drill bit bores at regular spaced-apart intervals along a central line, a pair of lateral legs with sharp ends, and mounting holes corresponding to those of the lock or strikeplate. The template is designed to be hammered into the door edge or jamb until the sharp edge-ended edges define the outline of the lock flange or of the strikeplate as well as the amount of wood to be removed to form the mortise necessary to nest those elements. The template can be screwed in place through mounting holes that correspond to those of the lock or strikeplate. A drill is used to rout the cavity through the drill bit bores. Guides in either side of the bores prevent lateral movement of the bit, but allow slight longitudinal swing to remove material that may remain between holes. Lateral spacers are provided to align the template against the angled part of the door jamb.
