Reply to: Roll Swaging vs Ferrule and Thimble

[quote=Edchris177][quote] (Roll Swaging - not sure how it got its airplane name) [/quote] Before fly-by-wire, all planes, (and small airplanes today) used cables to control critical moveable flight surfaces, think ailerons, rudder, elevator. The early bi-planes wings were quite thin, & not strong enough to support flight loads, so they used cables & wires to turn the wings into sort of a truss. Some of the early ones were more wire & string than airplane.

An aircraft rudder works much the same as your Cat rudder. It would be rigged with a short crossbar mounted perpendicular to the rudder. On each end of the crossbar a cable would be attached via fork/pin. These cables would be routed through bell cranks & pulleys back to the cockpit controls, with each fitting safety wired. Often turnbuckles were used to allow for fine tuning, so your rudder pedals & control yoke were not cockeyed, & to adjust tension in cables. With most aircraft swages a preservative compound is applied to the cable before insertion into the terminal barrel.[/quote]
