Love it Ryan!
Sorry for the pain sanding those pockets smooth, but your efforts look great! Was that soft or hard maple?
I hesitate using any lock that needs batteries. They die before you get to replacing and then what? Aside form that it's a cool idea.
I've been contemplating a spring loaded pin that locks into a hasp. A properly powerful magnet could pull the pin back and the spring keeps to from being shook open. Alternatively, a pin that needs to be slid side to side with a weaker magnet (no springs) and will only free the hasp when somewhere between the two ends so timing or shaking wouldn't work either.
Big plus on putting in the pattern 👍
