Rubber-Band Powered Escapement w/Pendulum

This is a test jig for, and a derivative of, the parametric escapement mechanism I posted yesterday: http://www.thingiverse.com/thing:7785

The intent is to power the escapement with a rubber band and see:
1. whether the pendulum regulates the unwinding of the elastic and
2. whether the escapement in turn keeps the pendulum moving despite friction

I suspect it will NOT work as is, but some parametric tweaks might get it going. May need to add some other weigh at the end of the pendulum,
