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.
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 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.
