A new clock making book from John Wilding is something to celebrate, and this is no exception. What is unusual about this design is that there are no “meshing” gears in the mechanism, making it much simpler to construct, although the author says it isn’t really a project for the beginner, as there is some precision machining required in making the pin wheel. It is a wall clock, and not that ornate, although the mechanism sounds fascinating to watch. Full drawings and building instructions. 33 ringbound pages. RiteTime Publishing Limited
