Wow. Was totally expecting a mill operation for the head. Is it safe to use a 3 jaw that way?

It couldn't fly out, locked in by the T shape. I do weird stuff in 4 jaws, ive made 3 jaws hold square parts, but ive never seen anyone do this before. Over 25 years of being a machinist and still learning!

I'm not a machinist but that doesn't look like a normal or particularly safe way to cut those flats.

Definitely not normal but no less safe than anything else we do.

Part longer than lathe, forklift/crane tailstock extension. Its just polishing, not cutting so there isn't any tool pressure. Sketchy but it spins slow and could only fall down, not fly out.
