how does one "adjust true"? I know their is the 4 1/4" allen screw around the the 2nd part of chuck! When I screw on to spindle (Logan model 200 lathe) I get .023 run out on out side dia of chuck same as what I get when I chucked a 3/4" drill in to jaws! The lathe spindle has less than .0005 run out!
I took chuck apart to clean and lubricate I punch marked the 3 parts, the jaws are in their correct locations, the pads for the adjusting allen were installed at bottom of allens!
Turning the 4 allen adjusters in-out like one would do on a 4 jaw chuck, with chuck on spindle just doesn't do any thing in reducing the run-out! Totally befuddled,
