1st September 2011 - Terminating the rudder cables

The rudder cables had been terminated at the front when the basic cable routing had been laid out. Now that the floor panel which they pass through was in place it was possible to terminate the rear of the cable. First the rudder was installed, centred and and clamped into position. Then the rudder pedals were clamped together in a neutral position with the rudder horns precisely vertical. The rudder cables were then terminated using nicopress fittings around AN100 thimbles and AN111 rollers. Glue lined heatshrink tubing was applied over the nicopress fitting to exclude any moisture and protect against the sharp cable ends. The cables were cut so that the holes in the rollers were 4cm from the holes in the rudder horns. Two pairs of coupling plates were then fabricated from strips of 1/2" x 0.063" 4130 steel plate to join the cable ends to the rudder horns. These just need priming and painting and then the rudder system is ready for when the aircraft is assembled ready for flight.
