Crank Hole Finish Size For Pilot Bushing

To throw another idea out there.
If original indersized hole is deep enough but is not running concentric. Turn up and press fit a solid bearing bronze insert and press it in. Then drill and bore it out to size and running true.
I have done mine long ago on a mill with crank mounted vertical hanging off side of table. You can then use boring head/tool to finish it.
