A friend gave me a large piece of native Missouri black walnut from a tree that had been felled by a lightning strike. After making a couple of ships, a WW1 British bomber (it's up at the library on display now), and some other small things, I decided to do something different.
I made a "dead box".
It's kinda like a time capsule since it contains things personal to me with some value, including historical, and only I know what's in it. It's just a simple wooden box with some handles for decoration, but no lid. It's completely sealed and assembled with dowels and wood glue. No metal in the construction except for screws attaching the handles, but the contents rattle when it's shaken. Two items of value are over 150 years old.
Somebody will get it when I pass away. Morbid? I don't think so.
