Thanks Bruce for making a video about my magnet method. Using photo corners is much easier than sawing notches into the magnet. I'll be very happy if anyone finds it useful. One tip that II would like to pass along is that you really don't need super strong magnets for the bow to hold. In fact, super strong magnets will be difficult to slide around. Taking this idea one step further, I am planning on buying a sheet of galvanized metal as a work surface. This would eliminate the need for a ruler. Other magnets can be used to hold down the bow and sail as the glue dries. If it works any better, I'll let you know.
