RO sander is a critical tool if you're doing anything beyond rough framing. In a perfect world you want to cut or scrape your way to exactly what you need, but at the end of the day the sander goes brrrrrrr.The RO sander is almost idiot proof. Sometimes the velcro can drop the paper and I'll accidentally sand away the velcro before I notice. Other than that, you start with a low grit to cut away more material. Then you work your way up to eliminate swirls. I don't go under 80, that's belt sander tear shit up territory. 120 and 240 give good finishes. Past 320 can impair stain absorption. You're getting into paint polishing and blade sharpening grits in the high hundreds and 1000s.Think about what you're doing when you're sanding. 60 grit belt sander is ripping away whiskers of wood like shredded wheat. A hand plane carves away shavings. RO is always cutting circles or spirals into dust or fine powder. Proper technique is to use a finish sander to final sand with the grain, especially when you build something from scratch or need perfect stain and finish. Most jobs and people will never know the difference, RO is plenty.
