Who said just run a hack saw through one side of the race? How very dare you suggest such a thing? But you could just clean up the cut with a file and you have a split race? Get behind me satan.
It's not a race, it's a collet. Once you've accepted that, it becomes natural to accept that it should have exactly the same split in it that top one has 🙂
