What is the fastest way to sand wood by hand?
Slow and steady wins the race. For faster hand sanding, you just press harder and move faster. But with a random orbit sander, that strategy will actually slow you down. Too much pressure or speed creates tiny swirling scratches that you’ll have to sand out sooner or later (often later, after stain makes them visible).
