I don't have any of the jaws. But you are aware, I hope, that in order to get any reasonable runout with jaws that didn't come with the chuck that you will have to make a fixture and re-grind the replacement jaws?

So yes I am on the look out for a tool post grinder as well I have seen people use a ring and grind there jaws like that and then I also so one where the guy did his on a surface grinder.
My other 3- jaw chuck that I have the jaws on that need to be ground because it does have some run out in them but as long as I don’t take the part out of the chuck I’ve made do like it is .
