The rudder tapers fore to aft. The round groove at its back edge to accommodate the rudder shaft was milled on the milling machine.It just didn't look right having this rudder appear to be one large piece of wood. It probably was made up of boards jointed together, cut to a pattern and reinforced with iron straps.A small thing that probably won't be seen at all from viewing distance, but it was enjoyable to go through its construction mentally as if you were building it and make it appear that way. I think that's why many of us enjoy modelling so much.
