It is nice to agree wih another fellow but what are we talking about ?

The attached pictures may help the readers understand better what we are talking about.

Notice that one illustration shows what I was referring to namely to have both nearby surface rounded and just not touching.

I find it regretfull that those illustrations DO NOT take into account the problem of the glue having no place to go while inserting the hinges else than return toward the rotation axis, jam it all up even with applied vaseline and of course an interference fit as should be means that excessive force is needed to push the hinge in place.
Perfection is not of this world but we can improve on it by providing an exhaust for the extra glue that has to come out. I sure hope fellows are not using CA to glue these hinges. When they pick up dozens of pieces theymight never know the crash was due to a failed control surface.

P.S.: Sorry I do not know how to write captions to the pictures in this forum.
