I’m restoring a vintage bicycle and I want to get the rust off these cogs. This is a budget build of sorts so I’m trying to use as many of the original parts as possible.
The manufacturer is Shimano by the way.

not likely, if you can’t find any visible points of detachment…there isn’t any. some of these have spare parts for the smallest cogs and the rest of the assembly is held up by only one point for the lower end market and the higher end are put together with more attachment points.
Looks like probably a freewheel and not a cassette? Likely not taking that apart
Freewheel, not cassette. Lot of work for not much gain. They unscrew.
Looks like you took apart the body.
no, that’s a freewheel and cogs are integral to one another.
Definitely a freewheel. Get a wire brush wheel with stem that can be chucked up in a drill, if you don’t have a grinder with wire wheel. If very good at long tedious work, you could do it by hand with a wire brush…not easy.
It’s possible and a pain in the butt. You need to cassette removal tool, it’s easier when it’s on the wheel. But, it also has over a few decades of being on there, the smallest cog is basically screwed on the so, one tool on that and the other on another one and good luck. Lolol maybe soak it some penetrating oil over night. Ive done it.
It’s a freewheel, freewheels are rivitted to each other meaning you cannot remove them, just use a wire brush and some rubbing alcohol to remove the rust but normally when you put the chain on, put some lube and the rust should go. Happy riding
You can unscrew the small cog If you have two chainwhips, one forward one backwards. After that the rest of the cogs should just slide off. Look up Shimano uniglide removal on YouTube. It will be very, very tight.
