Making straight, smooth and accurate crosscuts and angles on framing lumber is a breeze with the new Saw Glide from Stanley. To make crosscuts, you hold the lip against the far side of the lumber and make the cut with the circular saw table riding on the slippery plastic surface of the saw guide. But the feature you'll love most is the built-in system for cutting the roof slope angles on the ends of rafters (Photo 2). You drop a nail into the appropriate hole and the nail sets the cut at the correct roof pitch, say 7/12, automatically. It even has holes drilled for the correct angles for valley and hip rafters. Available wherever Stanley tools are sold.
