>> Are we talking about the bushing at dead center between the two elevators? If so, I redesigned that. I inserted needle bearings inside each elevator tube. Next I took a steel shaft (recycled from an electric motor) and inserted it in aluminum fork in the middle. Now each elevator tube slides into the steel shaft. No way for it to work loose. I can send photos if anyone's interested.

From what I am guessing is that the left elevator has the pressure of the pitch trim spring and the right elevator has the downward pressure of the sparrow strainer.
