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.
Yeah like Martin says, there are oh so many ways to skin a cat when working on 3D, there's usually not just one right answer, they are all right answers. You'll find one approach better than the other, but rarely incorrect and the depending on your situation, those approaches change, so not to worry.
Thank you for your input. This is why I would rather pay to get a good education about Blender than just watching YouTube videos. Don't get me wrong there are some great vids on YouTube (Blender Guru, Ryan King). But you folks explain in much more detail the tools and ways to use them. So, thank you once again.
