MF_BOSS on Sat,

As the saying goes - those safety regulations are written in blood. Which is to say enough people tried "it", and were "lucky" until someone got killed.

Have you figured out what caused it?

I've seen my Taig unscrew the chuck if the tool bit is still in the work when the motor is shut off.

Scary scary. Glad you're ok.

Like the others, glad you were not seriously injured. It can happen so qu ickly.

Threaded on chuck? And cutting the far side in reverse? shame shame ....

I'm also wondering how this happened. Did the spindle break and thus the w hole spindle, chuck and pipe were loose? Or did you turn the spindle in re verse and cut on the off side, thus untightening the chuck as you cut? Nor mally chucks are screwed onto the spindle so that when cutting, you are tig htening the chuck onto the spindle as you cut. Kind of like if you put a n ut onto a bolt and then always turned the nut to the right when handling th e bolt/nut. You are always tightening the nut onto the bolt. It can't loo sen. But if the spindle broke, and the spindle, chuck, pipe were all in th e air, then yeah things can get dangerous.
