Finding the center of a worn shaft can be difficult if the wear is non-uniform. Many times the wear will result in an egg shape or flattened section. The best approach would be to try to work off an unworn section as a reference. If there is enough of an unworn section to rest on a v block and you have a second v block to support the back end of the shaft then what @mmcmdl suggested should do the trick. Otherwise mounting the shaft in a 4 jaw chuck and centering on the unworn section. Then center drill the end of the shaft.
