First off, I just want to say that that is a very awsome looking bow. I have never built a bow, but wish to try someday. I know there are many good books and videos on the subject which I am sure I will review before I actually start, but I am curious about the tillering of a glass bow. I understand the process of tillering an all wood bow, by sanding, cutting, and rasping away belly wood and the sides of the limbs, but this just doesn't seem logical to do on fiberglass. Am I wrong and this is how you do it, or is there another method entirely, or do fiberglass bows just tend to not need much tillering? I am curious.
