After using a coping saw for years to cope the inside corners of crown molding, I figured there had to be an easier way to do it. There is. Now I use a rotary tool, a spiral wood-cutting bit and a small base. First I cut the compound miter cut as I always did. Next, with the molding clamped in position as shown above, I place the tool base flat on the miter-cut end and carefully shave away the waste nearly up to the profile edge. After a little cleanup work with files and sandpaper, it’s ready to install. I find it quick, easy and much faster than sawing.
