Match drilled rudder to ribs and hinge….found it was slightly skewed from original cutout and bend and never corrected. OK, maybe more than slightly skewed. About 1 inch potato chip shape. No way to fix this easily without making it look like it was in an accident. Can salvage horn without ribs and hinge. Can use the skin for other sheet metal parts (ribs, etc.). If this is like the elevator spar I can make all the parts over again in a fraction of the time it took to do the first time. Maybe one day, 8 hours from beginning to end if all goes well
