Unboxed parts for rudder including angle for stiffners and 2 rudder skins. Took a little studying to figure out where they were coming from on the stiffners. There are holes marked on the stiffners that are designed to guide you to make the angles you need to cut so it is not neccessary to measure angles. Wow, this is rediculous how easy they make this. I think about David making all his parts from scratch. Using blue sharpie, I connected the dots with a straight edge and cut them with the bandsaw. Finished cutting RH side stiffners, filed and deburred them. Then match drilled them to the skin, deburred and dimpled.
