    MEASURING HALF MORTISE LOCKS:
        • Before looking for a replacement it will be necessary to measure your lock.
        • Please view diagram to determine how to measure your lock.
        • The backset measurement, is the most important measurement, must match precisely
        • Once the backset measurement is determined you can look at your various options.
        • If potential substitutes have different lock-body or lock-plate measurements cabinet work may be necessary to fit the lock.
    INSTALLING HALF MORTISE LOCKS:
          Determine desired location of lock

          • Adjust position to allow for location of keyhole as it is often off center in lock
          • Mark location of lock on drawer or door interior
          • Hold lock at desired location against drawer or door interior
          • Selvedge edge should be level with top of drawer or edge of door
          • Trace outline of lock on drawer or door interior
          • Trace outline of selvedge on drawer top or door edge
          • Inspect outline for accuracy , straighten lines where necessary
          • Again holding lock in position, trace lock-body
          • Cut shallow mortise for lock plate and selvedge with router or chisel
          • Selvedge and lock-plate should be flush with the interior wood surface once installed
          • Cut lock-body-mortise. Okay if off slightly as lock-plate will cover lock-body once installed. Be sure there is ample room for mounting screws to attach lock
          • Use of a strike is rarely necessary on drawers and doors. Traditionally a simple mortise was cut in the wood to accept the lock bolt.
          • Notched strike is necessary for boxes and chests with lift lids

    Keyhole Placement

          • Measure distance from top of lock-plate to center of key pin
          • Measure distance from side of lock-plate to center of key pin
          • With these two measurements locate keyhole on furniture front, make sure key pin is aligned with keyhole location
          • Drill small pilot hole at key pin location, hold lock in position and check to make sure hole lines up with key pin
          • Drill hole larger to accommodate key barrel
          • For a finished appearance: mount an  escutcheon/keyhole plate, on furniture front.
          • If Using Strike (for box locks)
          • Align strike on underside of lid
          • Trace outline of strike in position
          • Check strike alignment and make adjustments if necessary
          • Screw into place

    If Using Brass Wood Screws

    Care is required when installing brass screws. While these screws are the best match for most antique hardware however they are not as strong as steel screws. The screw is easily damaged if the hole is not properly prepared.

    The best practice is to first drill a pilot hole. Use a drill bit slightly smaller than the overall width of the screw, including threads, to drill the hole. Then use a steel screw, the same size as brass screw, to “cut threads” in pilot hole, by screwing steel screw into and then out of hole.
