Centring in a 4-Jaw Chuck

[KellisRJ]

4" , 8", three jaw, four jaw, collect etc and each one has a different size chuck wrench.

I was once taught to identify the real problem before trying to implement a solution. And sometimes the answer is the first common option: Do nothing. Or leave all but the one you are using in a handy place where they are still handy, but where only the one in use will be hung in the "In use" location.
