Remove the rudder and set it aside while the hinges are fitted to the tail fin.
Hold a hinge in position and drill the top hole only and temporarily fit the hinge in place with
a rivet as shown above, then carefully reposition the hinge so that the hinge pin is parallel to
the back of the rudder and drill the bottom hole and fit a rivet in that hole, then drill the
remaining 2 holes. Repeat this process for each hinge.
Put the rudder back in place using the spacers that you left taped in place. Make sure that the
alignment is still correct, then drill the top hole of the top hinge and fix in place with a rivet,
and then drill a hole in the bottom hinge and fix that in place with a rivet. Repeat the process
until all holes are drilled and each hinge is temporarily fixed to the rudder with 2 rivets.
Test fit the rudder using Clecoes to hold each hinge in the final mounting position, which is
inside the fin and inside the rudder as shown above. Remove the spacers and check that the
rudder can swing freely left and right at least 100mm from the centreline as measured at the
rear of the rudder. If there is any binding locate the source and correct it.
Mark the location of the end of each hinge pin (circled at above left), then remove the rudder
and all hinges.
