HF 8x12 Lathe - 3 jaw chuck true up starting at .007 runout - need help

Hi Spud. If you look at the guts of the 3 jaw chuck, it is completely uniform, except for the jaws. The scroll is continuous, so it doesn't matter where they are inserted as long as they are in order.View attachment 70910

Reminds me that I need to take mine apart and clean it out. It has been getting a bit "gritty" shall we say...

I agree. I just remember reading/watching something that said that 3 jaw chucks had each slot numbered and only a certain jaw was supposed to go back in that slot.
