I finally tried that old-school trick for chatter on thin walls
For years I thought the guys talking about using a rubber band on the tool holder were just messing around. Then I had this one part, a 6-inch aluminum tube with a 0.040 wall, that just would not stop singing no matter what speeds or feeds I tried. Out of pure frustration, I wrapped a thick rubber band around the holder like they said. The chatter stopped almost completely on the next pass. Has anyone else found a weird trick that actually works when the normal fixes fail?

That trick reminds me of using a zip tie on a router bit for the same reason.

Wait, you put a zip tie on a spinning router bit? That sounds like a good way to launch a little plastic missile across the room. I get the idea of adding mass to stop a vibration, but on a router going what, twenty thousand RPM? That zip tie is gonna stretch and fly off before you even flip the switch. I'd be hiding behind the workbench.

Rubber bands and zip ties just seem like a band-aid fix to me. If the chatter is that bad, maybe the setup or the tool itself is the real problem. @casey342 mentioned a router bit, but that's a whole different kind of tool. It's hard to believe a piece of rubber is a real solution for a machine shop. Wouldn't you want to find the actual cause instead of just quieting the noise?
