Here’s the first video that introduced me to him, a wooden excavator:
See how the entire thing is made of wood. There’s a bunch of different gears, and different transmissions and gear boxes that change what is actually being moved. All through two leavers. This is more a feat of engineering then it is wood work, but it’s both!
Here’s another wooden marvel, a crane that rotates 360 degrees, has an articulating arm with a claw!
His works of engineering art aren’t limited to just earth movers, here’s a wooden wood pecker that’s spring wound:
