power tool called a random orbit sander can smooth wood regardless of grain direction, with little or no cross-grain scratching. Palm-style models are ideal for general workshop use. A relatively new Canadian invention called the Sander Sitter is a device that lets you put down a random orbit sander while it’s still spinning, instead of waiting for it to stop turning after switching off. The Sitter has a crepe rubber pad that automatically cleans the sandpaper as it rests on it.
