I have been making segmented pieces for a while now. Have also been playing around with oval turning and building a wooden chuck to turn ovals. Then it dawned on me, why not combine the both? The photo shows the finished project. First one is of the "thing" complete, and the second photo is with the lid off. The real challenge was developing the angles and sizes of the segments. Dimensions are 125mm high, 90mm x 75mm.
