I have a piece of limestone that was given to me, which I plan to use as part of the counter surface in my kitchen. It's only about 30 cm wide, so we're not talking about large pieces. The surface is quite rough, so I'm planning to sand/polish it a bit. I'm not looking for a high gloss, just want to remove the worst roughness. Larger holes and cracks I think I can fill with some epoxy.

So here's my problem: how do I do it? I've never done this before, and I have a very limited machine park. I have a belt sander that gets the job done, but I suspect you should ideally wet sand when it comes to stone? I'd prefer not to buy a machine for a lot of money that then doesn't get used again.

Maybe you can rent a machine for a weekend?
 
what machine do I need? air-powered random orbital sander?
 
Depends on the appearance you desire and how much time you have. You can get far with Biltema's wet sandpaper and hand sanding. It's important to have something flat to hold the sandpaper with and to move from fine to finer paper to achieve the right finish. You can get a very fine surface if you have been careful in every step. Epoxi, etc. I would avoid.
 
I want to clarify that the deepest holes will be difficult to get rid of even with a larger machine; it is better to ask the local stone company for a price, such a small piece is easy for them to fix.
 
ok! I'll take a round at jula or biltema and see what I can find. and skip the epoxy. and sure, it's possible to outsource it but I see quite a lot of value in learning how to do it myself.
