I have talked to several machine service people and have discovered I made a big mistake taking the ball screw out of the ball nut to get the table off the mill. I now need a ball screw & nut expert to tell me how to put the two back together. I'm learning fast some of the the "don'ts" in machine service and repair. In my post below I refered to the ball nut as the "ball screw" and the ball screw as the "screw" so along with the "don'ts I'm also picking up the proper terms. Anyway, I am praying someone can help me get the ball nut and screw back together. Thanks, Jack.
