I am building a ringmaster and thought I might use a carbon fiber rod instead of a bolt or metal wire for mounting the bell crank. I know the bolt or metal rod is much stronger but the distance between the plywood mounts is so short, about and inch or a little longer, that it seems in order to break a carbon rod that short, the ribs would give way first under the pressure. Thought I might save some weight. Has anyone done this with success?
