Square In 3 Yaw Chuck

[Slavko]

That's amazing. But the guy actually does hold square in 3 yaw chuck without splitted pipe. At 2:47 is that clearly visible. I can hold piece in that way if I shift jaws in chuck and be near in center. (I don't have that big piece of round material to make jig.) Seems that I just need to try and work with slowest RPM if something fly away.

2:47 only to square up, not concentric
3:10 to hold the square, concentric
easiest is the split pipe

I already do. Like on 2:47. I do offset one yaw for one scroll spiral and got piece near the centre. Just right for job needed.

Watched this the other day. Making one of these was a final exam at the local CC for your CNC Programming final.

This dude does it on a manual lathe, with a 3-jaw chuck.

Thanks for sharing this video. The machinist is incredible at his task and I have learned a new way to hold something in my three jaw chuck.

Ran 2400 square parts in a 3 jaw, 2 fixtures with square recesses milled in the, face, four tapped holes to hold the parts in place, repeat again and again.

Happy Black Friday
