You leave the register diameter on the backplate a bit undersized, and it allows you to loosen the mounting screws and tap the chuck into any alignment you like. Note that no 3-jaw chuck can be trusted to hold any diameter exactly true, it always has some imprecision. So, when a critical job come up, you clamp the work in the jaws and then adjust the chuck to run the part true. A good chuck will then repeat that position pretty accurately for the same diameter.
