So a few years ago I tried French fitting some of my tool chest drawers as an experiment. I was blown away at the difference it makes. By having cutouts explicitly for each tool you know exactly where each tool lives, and can tell at a glance if any of the tools were not put back after the last time they were used.
So thing number four is a French fitting of one of the drawers in my watchmaker’s bench, adding a cutout for the Nibbler. I only use the nibbler infrequently, but when you need it, it is exactly the tool you want. That makes for an ideal tool to French fit, since you know exactly where it is next time you need it, even if that is several months later.
The nimbler is spring loaded, so I added wooden risers to hold it in the much smaller closed position in order to save drawer space.
