I've been meaning to make a "bump tool" that has a dovetail for my QC tool post.
If you measure the "ID" between a pair of rounds clamped to the tool post dovetail in the unlocked position, PLUS 2 sheets of paper, that's the right spacing. Machine a block to that dimension so that you can firmly clamp them for welding.
If you do the rounds, you don't have to use a tool holder.
I think bronze could successfully be substituted for the roller bearings.
here's a quick n dirty sketch:
