Designed a system to measure at 1/8 of an inch above centerline on trailing edge tube of wing. Measured each hinge position and marked. Straightened hinges as they were a little twisted from the factory. Made jig out of 1/2" angle iron to drill rivet holes in the ribs. Works great except it didn't line up with a few holes I had already drilled so I may change those ribs. Drilled all holes in ribs and sanded ribs. Cut aileron to length 1 1/2 inches from root and.
