Robin Rinzetti recently put up a YouTube on how he trues up Lathe chuck jaws that I found very informative. As always, he explains it all very well.

Grind them..and always use the same place on the chuck to tighten the chuck. Of course this is only on a live chuck. Independent chuck doesn't matter unless you're worried about it making up the part it's chucked onto. In that case, indicate a say 1.250 part into the very back of the jaws and dress the jaws for that diameter part...but I don't do that and I imagine it might be tough to indicate the part at the rear most of the jaws. I guess you could machine a part from a single setup, turn the od and bore the id, as well as indicate both a close as possible...then indicate on the id to dress the jaws.

Maybe this one: https://www.youtube.com/watch?v=jhreM8WK4zE . He's usually pretty over-the-top.

I finally got around to watching it. What surprised me most was seeing a Shars indicator! (He probably rebuilt it and replaced the sapphire bearings with PCD coated titanium or something, and I just missed that video...) This one actually seemed within reach of mere mortals.
