I installed the bolt ends and lock nuts appropriately and adjusted them until the centre of the hinge pin was the specified distance from the front of the spar web.
I attached the rudder to the Vertical Stab using temporary hinge pins. All this is not actually necessary right now but I wanted to check that everything does in fact fit correctly and, more importantly, I simply had to see what it looked like!
Needless to say, the alignment and fit was perfect and the rudder seems to "glide" from side to side... smooth as silk! ;)
