I want to satin a yoyo, what do I need?

Like the title, I want to try to satin my beat to crap Tactic, but I don’t know if the tools I have would be good enough for the job. All I really have is a drill, and sandpaper. Could I do a decent satin job with these? Or do I need a Lathe to make it at least half decent? I don’t plan on polishing it

Those tools will work just fine.

For sandpaper, it’s best to at least have rough to really fine. Then you’d use rough, then little less rough, medium, medium fine, and fine. That way it’ll look nice too, and not look so sandpapery.
