Piano key action

I play piano since I was 13 and with this project I want to honor this wonderful instrument, very rich of color and expression. My other passion is of course LEGO, so the idea was to replicate the complex functional action of the piano using LEGO bricks, with working moving parts.

The model includes: a piano key (in white); the action (in red); the hammer (in yellow) and the damper (in dark grey) near the string (in light grey). When the key is pressed, the damper rises and the action pushes the hammer, which "jumps" on the spring and suddenly falls down. There is also a replicate of the sustain pedal action (in black), that can rise the damper, allowing free vibration of the spring.

The movement is not perfect, so I'm still working to make it more fluid and I also want to add the double escapement mechanism. I think that this model is fun to build and play with, and it is very useful to understand the mechanics of this complex instrument.  

Thanks for watching and happy building!
