Safe-T-cable = Brilliant ! especially doing boroscope plugs on a CF6 or a V2500 downside of them was expense ( often in BA at LGW they were nil stock on the wire or the thimbles )
Most intricate wirelocking I remember was on the coal burners ( JT9 s) the throttle cable adjusters and the myriad bleed valves buried under the diaphragm ( seemed to be at least one for every day in the month ! )
