Hollow-Shaft Wooden Sculling Oar Plans

The pictures in the instructions are dark and black and white. Hard to see the details. The instructions themselves are a little hard to follow but adequate. I figured it out. The packaging was a flimsy square cardboard tube and my plans were wrinkled and bent up from shipping. I think a stout round tube would have protected it better. I haven't built the oars yet, but I like idea and looks of what they could be.
