This video describes the use of an inertial flywheel for a clock that I am making. The design process is described and Fusion 360 is used for the CAD & CAM. The flywheel is machined using the Cavera Air desktop CNC. In the final chapter the flywheel is shown installed and working on the clock. ------ Intro 00:08 William Bond, US clockmaker 00:34 Prototype flywheel 01:28 Work holding on the CNC 02:52 Fusion CAD/CAM 04:45 Carvera Air controller 05:45 CNC machining 09:22 The finished part 10:08 Flywheel installed on new clock -----
