Found a trick to stop my mill from chattering on thin wall parts
So I've been fighting with chatter on some stainless steel parts for weeks now. These are thin wall tubes about 0.040 inch thick and every time I tried to take a finish pass the whole thing would ring like a bell. I tried slowing down the RPM, tried different feed rates, nothing worked great. Then last Tuesday a older guy in the break room said try putting some rubber bands around the part before you clamp it. Sounds crazy right? But I grabbed a pack of thick rubber bands from the supply closet and wrapped two around the tube near the middle. It dampened the vibration almost completely. The finish came out way smoother and I didn't have to scrap a single part. Has anyone else used rubber bands or something weird like that for damping vibration?

That rubber band trick is wild but it makes total sense. It's like how tapping a wine glass stops it from ringing, you just need something to break up that energy.

Balled up some sticky tack and stuffed it inside a thin tube once, worked great.

@joseph_bailey I did something similar with a piece of rubber from an old bicycle inner tube. Just cut a little strip and wedged it in there, stopped the rattle dead. The sticky tack idea is smart too, I might try that next time.
