I just compleded a skeleton seperation prop with a wiper motor. I found a crate from a grandfather clock. It's about 7 feet high, 30 inches wide. Made into a jail cell. The motor lifts a drops the torso from the skeleton's hands and arms streched over his head. The hands and arms are tied to the top, and so he looks like he's doing pull ups, leaving his legs stationary in the jail cell. A cardboard screen between the skeleton and the motor from skeleton with pulleys attached at the top.
