Never use an angle grinder on rusted pipes

How do mechanics and machinists perfectly sand a rusted metal pipe?! 🚀⚙️
When a heavy metal cylinder or pipe becomes covered in thick rust, removing the oxidation can be incredibly difficult! If you try to use an angle grinder or a power sander, you will easily gouge the metal and create flat spots. If you try to sand it by hand, it will take you hours!
To beat the flat-rate clock, old-school machinists use raw physics and friction! In this incredibly satisfying restoration video, the mechanic tightly wraps a sheet of blue sandpaper around the rusted metal cylinder. Next, they wrap a braided rope over the sandpaper and pull it rapidly back and forth! This intense mechanical friction perfectly spins the abrasive against the rust, grinding it away in seconds! After a quick spray of chemical parts cleaner, the raw, polished steel is flawlessly restored without a single scratch!
