Question regarding Amati Nina keel

[1213brett]

How do you shape the veneers to fit the stem and rest of the keel? Do you just cut them to the rough shape and then glue them on and sand them to the final shape. And how do you find the angle of the veneer nearest to the hull? Do you just eyeball it then cut the veneer to your estimation? That seams hard to me. I was thinking you could take some really thin wire or solder and bend it along corner of the hull and keel. This in theory should give you the rake of the keel.  the problem after that would be putting the wire at the right angle when you transfer the rake to the veneer. I was just thinking may be there is a secrete I don't know about.
