And he should no better lol - RobWilson - 10-13-2014
Here you go lads , this is why screw on chuck adapters on a rotary table are a bad idea .

Yeah, I could see that coming. There's nothing like a self feeding end mill to ruin your day.

He made my reaction time look fast. Perhaps I do have ninja-like reflexes after all
I can't really comment though, as I haven't got my mill up and running yet but after a few days spent in central MA in a couple of weeks, I will be so much closer. I'm sure I will make similar mistakes but I don't think I will post them on YouTube!
I'm already sporting a bruised finger after slipping whilst polishing a part and introducing my finger to one of the chuck jaws. Amazing - one slip, minute cut, lots of blood and some colourful language. Not to mention my mate rolling around laughing!

That video is a 6 hour download for me, so I'm guessing that the chuck came un-screwed? I've often wondered why dividing heads have threaded noses, for the same reason..
RE: And he should no better lol - Highpower - 10-14-2014
Not exactly. Adam was making a lock ring for his horizontal mill, and he had it screwed onto a stub arbor that was held in his indexing / rotary head. This is a shot of the set-up before the "ooops" moment.
The lock ring unscrewed and came off - not the chuck.

Wrong side of the arbor, two flute endmill - disaster.
Leverage is in play on larger diameters. I managed to knock a rotab loose from the table using a 3/4" two fluter acting like a little impact hammer on a 10 inch ring.
Um.. no video of that one.
