nappen, there is a small tennon on the cocobolo base. The norfolk island pine has no bottom and fits snuggly over the tennon. Joint is made permenent with epoxy. I tried to make the grain patern line up, as best I could.
Very nice Gary. I like your finish for the NIP. I always had heard that there were many trips to the tank, not just put it in there for a few days. Your results look good.
