HI Wayne,
Yes, there are almost always several ways to do something in Blender. Kent did it this way, to be able to create that nice Bevel at ~6:19. You can also get that with your method, but then you’ll end up doing at least as much work. Or try and Bevel the cut, instead of the Cutter, but that’s gonna come with a lot of problems (try it) because of overlapping Geometry.
