These are tricky bows, the tiller shape would need to match the front view of the bow to say you truly produced a sudbury bow. Your demensions sound pretty good. I believe the radius of the bend should increase from the narrow part of the fade until it reaches the center of the widest part of the limb and then remain the same up to about 6" before the tips. Not positive on this one, I know it is tricky to really get it right.
