How to dismantle a cassette to separate cogs

I have a 7-gear Shimano HG cassette that I want to use on a hub that is meant for 8-11-gear cassettes. I can order al 3 mm spacer, but was wondering about another emergency solution: dismantle an old cassette and use one cog as a spacer. What is the trick to dismantle a shimano cassette? Use a drill?

IF it has the 3 rivets, a few strokes with a flat file will take care of them pronto. They are a soft steel.
A small nail w/ hammer can be used to lightly tap the rivet to start it moving, but usually you can pry them apart easily with a screw driver.
Some older Uni Glide (and others?) used a small, long allen screw.

Just buy the proper spacers. Come on people, it isn't rocket appliances.

If this was an emergency situation it would be a pretty odd one with a probably quite long explanation.

Some of the lower level Shimano cass. had rivets, others have very small allen head, 1 or 1.5mm. Clean the big cog end and inspect for either.
