Made this for my father's 80th birthday.
390 pieces, 9.25 x 7.25"
Some minor changes from my first, biggest change is the floating bottom.
I was thinking about a lower profile floating base without multiple layers.
I glued up two 3/4" thick half rings and hot melted them to a faceplate.
Used a small ornament tool to cut a grove, or mortise into the interior and then turned the mating floating bottom. Just enough play to expand, and tacked it with a drop of glue on the center of the end grain to prevent rattle. I am happy with the results and the curly maple bottom made it easy to sign the walnut base. You can see some of the assembly steps on my website in the "news and projects" page..
