A very trick tool. Leave it to the Japanese...LOL
Previously used a diff ring holder made by Irrgang Racing Services; but, it would cramp my hands badly.

I know there are 4" dia x 1/2" centre hole wet dry 800 grit paper. These are used for disc sanders.
Have you talked to OD or Crashby about prepping diff rings? Polishing them is a no no because you have to tighten down too much for the diff not to slip.
@ Fordy
Didn't you post you have special way/ lube for building a diff but didn't want to divulge what it was?
