That's pretty cool. Next, glue different species of wood and cut it. You said you used the scroll saw to cut the inside. Couldn't you have drilled it out? What I like about this site is that when it comes to ideas, the cup is always overflowing.
I built a 3' x 6' table from two-by-fours that was meant for doing sanding and finishing of my scroll work. But my father-in-law gave me a lathe and the bench was the prefect size for it. So now I'm back to using what little space I can find, including an old typewriter table. My wife told me to build another bench after I moved some tools into the basement.
