This piece is built from bottom up. Waste block in chuck / base piece/ stack centered rings (18 pieces to a ring) up to where the solid cap is. I turned it in two pieces. The base is turned and hollowed and finished inside. The solid hard maple cap (top) was turned seperatley and finished inside. Make sure everything is centered and join the halves. clean up the outside/ remove waste block, finish of choice . I used a easy friction polish
