I watched both videos there is a part II. He did try coring it, what a lot of work. I just want to see what it looked like installed, and what it sounds like. Very strange, but cool none the less. +1 on an impressive show by the lathe. The second video is a little more interesting, never seen someone sit on their banjo to hollow the inside.
