I am working on sanding the hardwood hallway floor at the wifey's cottage. Its a small hallway with a chimney going through it so it would be hard to use a rented sander. Its like 6 x4 I am using a random orbital sander with Norton 60 grit. I want to go to a 40 to cut faster. Has anyone had any luck with other brands than Norton? The sandpaper is wearing out somewhat quickly. Anyone ever try the shopsmith, they are more expensive but maybe they will be good.
