This is an absolutly sick project. Thanks for sharing. I am so curious about the rails. Your said you are going to build them up and shape them, so the rails will be plywood from the outer stringers, out, right? Guess I have to wait and see. How about the plug...how does that work? Did you veneer the top and bottom at the same time? Did the veneer "eat up" the detail in your shapping, i.e. the concaves? Would you shape deeper ones next time?
Sorry for all the kooky questions, it is just really cool.
