Piccolo problema

Si è presentato un piccolo problema circa l'accoppiamento tra le centine posteriori della semiala sinistra ed il relativo longherone. Ho inviato una mail a Igor per avere delucidazioni in merito.

Ecco la mail in formato "integrale":


Hi Igor,
i have a question for you.
I'm ready for glue the rear ribs on the main longerons of wings (photo "ready to glue");



I put the ribs on a rod and i put them on the left main longeron but i see that the ribs are about 2mm larger than longeron. Now, i think that the plywood skin must have the larger surface of contact with longeron and ribs, and the 2mm of gap between plywood and longeron is no good. (photo "2mm gap")



I measure many times the distance between main longeron and rear longeron and other measure as see on the drawing and all fits ok! I think that the problem is the radius of the airfoil in the lower surface (airfoil.bmp)

What do you want that i do for correct this problem?
Have i to sand the lower surface of rear ribs to reduce the 2mm gap or no?
