On todays agenda - work on the database for the flying pig website and, much more fun, further experiments on a theme of belt drives.
I've adapted the belt driven model from earlier on to use the mechanism from yesterday. The rotor that the arm is attached to is now connected to the body by a simple hinge rather than a fully rotating axle.
The movement is smooth and free and it gives the model a real mechanical steam punk look! I like it!

Further experimentation with the flapper design.
It occurred to me that the flapper design doesn't need to have an axle joint. The range of motion is only around 190 degrees so a hinge should do the job. To that end I have knocked up this quick prototype. It looks promising. I'll trying putting it into a more complete tomorrow.
Off to see Inception with #1 Son now...
