Several years ago, there was a plan for this in a Wood magazine, which I held onto. Had an office Christmas party and so I put this together. I do not own a drill press, so making the center hole was a bit of a chore. Rather than glueing up a blank and drilling through it, instead I took four boards, cut a cove on each with a diagonal pass over the table saw. Then I mitered both edges on each of the 4 boards and glued them up. A pass through the band saw and attached the base. Finish is Danish Oil. Base is maple, column is birdseye maple.
