Crown molding adds an elegant touch to just about any room. The trickiest and, sometimes, most challenging part of putting it up is cutting tight fitting angles. Before now, this was an operation that required a bevel gauge, a compass a compound miter table and a good bit of patience. With the introduction of this digital protractor, angles are calculated by an on-board micro-processor and diplayed on the tool itself. This video shows how the device works, demonstrates how to set up the miter saw and how to position the workpieces to get the right cut the first time.
