Europa-List: Europa pip-pin recess

[Fergus Kyle <VE3LVO@rac.ca>]

Hello,
        I don't quite understand the process of elongating the pip-pin
holes. Mine are tighter'n a drum all round and so they touch everywhere
(presumably), whereas if I were to elongated any, then won't the long side
only be touched tangentially by the pin. Won't this then permit the long
side to be slowly indented, and won't the condition accelerate as the event
(and inner surface) wear on?
        What am I missing here?
Happy Landings
