As long as the mounting holes in the chuck line up with the table's T slots,you can mount directly. If you make a test bar that accurately fits into the hole in the table,put it into the table's center hole. IF this is a 4 jaw UNIVERSAL chuck,Place the chuck on the table and tighten the jaws onto the test bar. Then,tighten the T nuts.
The chuck should be close to perfectly centered. Universal chucks are only so accurate anyway. Open the jaws some,and remove the test bar,of course.
If an independent 4 jaw,you'll of course,have to indicate all parts you clamp in the chuck till they are perfectly centered.
