Just about everybody has one, but not everybody knows how to use it effectively. To get the most from your random-orbit sander, you need to know how to handle the sander correctly, what grits to start and end with, and how to check your progress. It's worth learning how to sand correctly, as sanding is the most critical part of the finishing process. Here, Teri Masaschi shows how to choose the right sander for the job, to use a light touch and a slow hand, manage dust and grit, and avoid the pitfalls caused by tipping the sander or using it on too narrow a surface. Then, she demonstrates the proper technique for sanding a tabletop and a frame-and-panel assembly.
