Re riveting a cassette
I was mis shifting and thought I bent a ring.
Upon inspection I notice one ring was completely loose of a rivet.
I guess I could re rivet the whole damn thing.
Is there any obvious reason I should not?

Yes. You might not have the tooling or skills. or you might not be able to create a rivet with the minimal heads that the common cassette ones have. (Specific rivets for the application using distinct anvil and die for forming the heads just so. These are no pop rivets. Andy

The rivets are to keep the assembly together at the factory. You don't really need the rivets and I have removed them when I clean a cassette. All the cogs must be flat. If one of them is bent or otherwise out of shape, it might be easiest to get a new cassette.

Unless the rivet in question is joining the cog with a spyder/carrier. Andy

So, @CrimsonEclipse, can you get a picture. Everything works better with pictures.

Ahh, good point. I was thinking straight through rivets. I didn't think about those spider rivets.

Rivet pulled out.
There's room for a standard solid rivet head between the cogs and won't interfere with the chain.
Yeah, it's a carrier connecting the 3 largest cogs.
None of the cogs look bent, just the third one pulled loose.
edit:
Steel rivet, 4.3mm or 5/32 diameter.
Not sure I want to replace a solid steel rivet with an aluminum one.

...McMaster Carr sells solid steel rivets, and it's not that hard to do a not so neat job of ponding one in there, and doming the insertion side.
But I'm not sure of the minimum quantity, which might cost you more than a new cassette. I would try my local commercial fasteners place, where they sell stuff like this in whatever quantity I request.

I doubt an aluminum rivet will fail before the cassette is worn out.
