Can You Build a Circular Saw Powered by Air?

Can you build a real air-powered circular saw using LEGO?

In this video, we start with a simple all-LEGO Technic saw before working our way up to a much more powerful LEGO machine driven by a custom turbine, powered by compressed air.

Along the way, we experiment with 3D-printed air turbines, safety mechanisms, different rotor designs, RPM tests, gear ratios, and even a flywheel, before finally fitting a real circular saw blade.

So let’s see what we can slice using the power of air!
