How to remove cassette rivets
Any suggestions on how to remove the rivets holding together this 10-speed cassette? The 11-13t cogs are loose but the 15-32t cogs are riveted together. I am used to cassettes where only the largest 3 cogs are on a carrier, and the smaller cogs can be taken apart.

If the goal is to have the cog stack fit fully against the freehub body's shoulder than just grind down the rivet head. If the goal is to separate the cogs from each other do the same then with a tiny punch hammer the rivet out. Andy

Thanks. I've read about grinding the head but I don't have such a tool. Do you think it'd be possible to punch out with a nail punch without grinding first?
Edit: tried it and nope.

If you think you are precision enough to wack at it, worse case is you created a paperweight.

You can drill the rivet heads out. Use a drill bit the same or greater diameter as the hole they fasten through. Center the drill in the rivet head as best you can (start with a center punch, if you have one). Low RPM is better for metal. Stop when the bit reaches the cog material, and the rivet head should become a small ring separated from the body of the rivet.

+1 with post #6 and it looks like the rivets on the outer side already have a small hole that can be used as a drill guide. Should be easy.

Not as fast but a hand file will work as well. Just take enough of the head off the punch it out.
