These ribs go from the leading edge tube to the spar tube, and from the spar tube to the trailing edge tube of the horizontal stabilizer, vertical fin, elevator, and rudder. So, they can be from 5-6" long to almost 24" long, depending on where they go.

The hand tweaking at the end of the process isn't a problem, except that it can make a beautiful rib look crappy.

I can't picture what you have in mind. But don't sweat it.

Let's see who's already solved this with a rigid yet narrow magic nosepiece design for a brake, so I can try to push these ribs out in one shot. If nobody, then I start getting nuts with adjustable pressbrake die sets and so on. THAT would be a complex little mechanism, for sure.

Thanks.
