    This video seems to finish before the end. i.e. George says: “at this point I can turn on the router”, and we don’t get to see the routing.

    I tried something very similar to this yesterday using 3/4″ white pine for the work piece and a piece of plywood for the template. Less than halfway through the trimming process a large chunk of the pine ripped off. I don’t know if I was going too fast, or trying to take too much off with the router, but it was very frustrating.

      I find that a ½” flush trim bit serves a huge percentage of what I’d use a flush trim bit for. A larger diameter bit has a higher rim speed (cutting speed) at a given rpm. This might give you a better surface finish. A large diameter cutter may also have more cutting edges, three or four instead of two, giving you more cuts per minute and a better surface finish. This could be a critical advantage on gnarly end grain or chip prone materials.
