Abstract: This invention is intended for gang drilling a predetermined pattern of holes, accurately located in a specifically sized pocket or mortise pre-created by other means in a wooden member such as, but not limited by, a door or door jamb, in which the purpose of these holes is to aid in attaching other physical devices such as, but not limited to, hinges by means of common wood screws. This invention is comprised of a system of roller chain-driven spindles which contain appropriately sized twist drill bits, all driven from a centrally located spindle attached externally to a standard hand-drill. An appropriately sized spring-loaded guide plate fits easily into the pre-created pocket or mortise allowing positive positioning of the invention's assembly but allows access for the twist drills to pass through the guide plate, for the purpose of drilling into the wood.
