I have wanted to build the tallow box that Roy Underhill demonstrated in his show. You remember the little box with the dovetail key, and two part lid that slid out and then slid back to release it? The tallow I had was in a little green tin, but it looked out of place in my toolkit. I wanted something that fit in better so I used a small block of cherry sap wood for the box, and a leftover piece of ebony for the key. I resawed the lid (twice) with the top top undercut where it comes together in the closed position. The body cavity was hogged out with a spoon bit (I got it cause I saw Roy use it and loved the flexibility it provides). The tallow came from amazon and turns out just fills the body cavity I made.
