Enter David Fletcher. While the UK-based designer, mechanical engineer and ex-antique-furniture-dealer appreciated Jupe's design, he figured he could improve upon it. "[Jupe] tables could not store their own expansion leaves, were not truly round in every stage, plus they were slow and laborious to operate." In 1997, Fletcher set about developing an updated design to address these issues.The Capstan Table that Fletcher slaved over is an absolute masterpiece of design and engineering.

By integrating the leaves into a multi-level design, adding a star-shaped centerpiece and tying it all together with hundreds of components and thousands of fasteners, Fletcher created an all-in-one, largely automatic design that never fails to knock my socks off:
