Video: How to make the Vidar's Chair crest-rail (with a surprise ending)

I've been working away on my Vidar's chairs and making good progress. Yesterday was a good day, as I glued up the backs of both chairs -- the first glue-up in this build. Pretty exciting! Next I need to make the crest rails and the back splats. The crest rail construction process is pretty complicated and difficult to explain, so I put together this little video after successfully cutting one out yesterday.
