The angle (length) of the crank can be changed from 150° to 175° - see the pictures „Minimum Crank.jpg” and „Maximum Crank.jpg”. This changes dramatically the movement of tiller, as you can see in the Video. You can edit the assembly and try the value of 179° instead of 175° to see the maximum dramatism... 

In order to control the animation I changed the names of five Angle constraints as you can see in the picture „Animation Constraints Names.jpg”. The „Motor” constraint is the angle of the crank (total of 3*360°), and the others are as follows (first value for the large crank and the second for the small): 

• Length from -25° to 0° controls the total angle of the adjustable crank from 150° to 175° 

• Crank-Mid from 24° to 10° controls the angular movement of the mid crank 

• Stud-Left from 153.32° to 165° controls the angular movement of the left stud 

• Stud-Right from 58.48° to 42° controls the angular movement of the right stud
