With cables in position the aileron control can be fixed. Tube 6-B-17-1 slipped in rear and front support. In fwd end a stainless washer 6-B-17-50 and a ring 6-B-17-5 should be installed. After some grinding and sanding the ring finally fit. AN3-15 bolt with washer and stopnut was carefully attached. To much torque will deform torque tube, make it oval. I think I am going to install control stick now to be sure cables are in right position, before riveting.
