Pin wheels simulation

It uses for me to determine speed of rotation of small pin wheel gear in order to hitting a hammers to steady plates. It make in SW 2007 and I will very much gratefully if someone can make a video file of this simulation. In this assembly is not exist any strange mates, contacts between bodies calculate SW and do it good. It added a gravity and rotation motor for simulation control. If you change a speed of rotation motor to high speed,at one speed hammers will fly a steady plates!! It's my birthday preset for all members of Grabcad community!
