I recently decided to finally get around to building a shadowbox for myself. I originally did a similar box about 10 years ago for myself, but a friend's wife wanted one for his retirement. Since my tools were packed for moving, I took my stuff out and re-did the insert for him.
I utilized walnut from a local urban forester and refined the lines of the design from the original design. I had some laser engraving done to utilize some of the open space on the bomb fins. It has a hand rubbed oil finish. I am very happy the way it turned out.
