Found something that works. Y'all tell me if I am screwing up. I have found that if I hit the jaws with a plastic faced hammer while I am tightening my chuck I can get every bit of the runout out. Thinking back, I've seen my friend and full time machinist do the same thing on both three jaw and four jaw chucks. Is this a standard practice or am I damaging my chuck?
Chuck is a new Chinese that came on my new Precision Matthews 13X40. Spindle face runs true as does the chuck body itself as long as the chuck is mounted in the same position every time. D1-4 mount. Never had these problems on my old Sheldon 11 X42 but it was a well worn machine of 1942 vintage
