Separate the F-886-L-1 & -R-1 Rudder Stops, F-810C-1 & F-811C-1 Angles, and the F-812B-1 Angle / Control Stop from the F-800 Angle Parts by cutting at the locations shown in F-800 Parts Separation diagram on DWG 70. Label each by part number before separating. Cleco the F-812A-1, and F-812C-1 Bulkheads to each other as shown in F-812-1 Bulkhead Assembly view on DWG 70. Final-Drill #30, all 1/8 holes common between the two parts. Use a hand seamer to open the bend angle of the flanges on the F-812A-1 Bulkhead (fwd) so that its flanges are parallel to the flanges on the F-812C-1 (aft) Bulkhead (DWG 70).
