I have been using the following chart for years to figure blade angles for compound miters. The chart was originally written for use on a table saw. When I got my Hitachi SCM, I computed the miter saw angles. (actually, quite simple. I just subtracted the Table Saw miter setting from 90 degrees to get the miter saw bed angle setting.) I've made everything from flower planter boxes to
decorative boxes in exotic hardwoods using these settings. They work very
well - Jim DeLaney
