“Remonter” is a wooden gear clock with a remontoire and grasshopper escapement.  It was designed using ACAD and toolpaths created with Cut2D.  The complicated parts (ie gears, etc) were fabricated on a homebuilt CNC.  This clock uses a combination of materials:  Cherry, walnut, birch, baltic birch plywood and brass.  The frame and dial are finished with tung oil varnish and wax.  The gears are left unfinished since this will most likely lead to a piece of visual art without function!  The clock is negator spring driven.  However, the springs purpose is to rewind the remontoire every 15 s and advance the clock hands.  The escapement is independent from the spring drive in the sense that the remontoire, which is driven by a 10 g mass is the only part of the gear train that influences the grasshopper.  The remontoire is a great way to get around the non-constant torque exerted by a spring.  You can see a video of the remontoire here:
