I have a siege c2a lathe and had a minor, but potentially dangerous, event today . Whilst drilling a piece of copper a vibration set in and one of the chuck jaws dropped out of the chuck. This caused the workpiece to dislodge but fortunately the drill bit stopped it from flying out, but ruined the drill bit, even though the chuck was at fairly low rpm. This seems a total freak incident to me....... how did the jaw just fall out? any ideas?......... I've replaced the chuck but am very concerned that this may be a problem with the standard chuck
