That, we knew, was the easy bit. I'd always had concerns about how we could cut the traditional crown shape on the top of the king, and had concluded that cutting the shape with a band saw, pretty much by eye, would be the best bet.
We fitted a fence to the band saw bed, set it to 45 degrees, and ran the cuts up to a pencil line by eye. The wood is not particularly cheap, and we had no spares, so we were a little nervous in case anything went wrong. It all worked out pretty well though, and barring a few edges that needed a last sand, it was done from start to finish in a couple of hours.
The only thing left was to sand them all off with an orbital sander, and put on a minimal 3mm radius round over on all the edges.
