Nice video - not rushed. I especially like how you mistakenly decreased the angle for the second trial and left it in the video. We all make those kinds of mistakes and it's nice to see an expert share in my pain! One suggestion - it's not really necessary to drill the hole and feed the blade for those trial cuts. Trial cuts don't need to be internal. You could just make some rounded teardrop cutouts from the edge and check the angle that way. Might save some time and the added effort of threading the blade. Great job on the demo and thanks!
Because he's not an engineer. An engineer would calculate the exact angle required for whatever thickness of inlay. I'm not attacking him, because I also tend to go with less preparation and a lot of trial and error in my woodworking - (I'm obviously not an engineer).
