Antique locks and latches are what make an old home unique, from the detail of the cosmetics to the vast variations in design. Whatever the make, there are basic components that they all have. Follow the link above for some photo examples from different manufacturers, some common and some not-so-common. If you're working on your own lock, here are some basic recommendations:
- work on a clean surface with no clutter
- take lots of pictures for reference, and remove one piece at a time
- try to keep each component in the same orientation as when removed
- use good screwdrivers with sharp tips
- when reassembling, use a dry lube (not WD-40) that won't attract dust
- if the cover screw is too tight it may bind the lock, snug is good in most cases!
