I spent a good half day polishing the ends of the rudder pedal weldments with emery cloth to remove the coating and then realised they were still tight in the plastic bearings, so I kept going until I got a decent fit. Using emery cloth on the steel ends is very slow going (any other suggestions) and removing material from the inside of the bearing (again, with emery cloth) didn't seem to work well. Anyway, when I installed the assembly in the fuselage, I found that because the longeron on which the bearings are mounted have a slight camber, the bearings have a "toe in" position which causes an increased rotational friction in the rudder pedal shafts. I believe the hole was drilled at 90 degrees to the bearing, but that's not the way they end up aligning with the shafts when mounted.
How much friction is reasonable? For instance, if I pull the rudder pedals all the way to a horizontal position (with the brake cylinders & pedals on) they will stay in place. The rotational resistance is what I would term "firm". I would think that when they rudder cables are connected and you are effectively rotating both shafts by pushing on a pedal, this force will double. Did anybody else face this problem or decision?
