Two Stage Gear and Crank.

This project is a two stage reduction gear with a crank output. The mechanism is fitted into an almost square topped box with the output crank close to the centre of the box top. The gear reduction is close to 4.5 : 1

Make the model as an exercise in pure mechanism or as the starting point for your own character based animated paper models.
