I agree with you. Both elevators have exactly the same issue. I didn't change the original radius that much during the attachment of the spar to the rib that it should change the alignment this much. Could it be a issue with the corner of the horn? But the skins fit perfectly on the assembly.

I have tried to make the radius smaller based on an advise from another builder. I used a large nail in the corner and a vise grid attempting to pull the rib to the horn, but it doesn't move. It is difficult to find grip on the horn without damaging it. As I already match drilled the holes in the spar, because they aligned perfectly, I rather not drill out the rivets that attach the spar to the rib.

If you would have an idea or method to do so, I would be very happy.
