There is a person on youtube who shows videos of himself making carbon-fiber jewelry rings to wear. In a lot of the steps he is cutting, and sanding carbon-fiber. Most of this he uses a lathe and drill-press for. While this looks interesting, I have seen more than one person exclaim shock at him for advocation of doing this. From what I understand, the dust from this material is extremely toxic, and has no use in a workshop. The carbon binds to anything, and everything, including lung tissue and stays there. Can someone correct me if I am wrong? The person who makes these videos hasn't made any responses on the concerns, and also has done quite a few other SAFETY violations when I watch him.
