I am surprised that the No. 3 rod has the No. 2 rod beat in number of
incidents. I believe that I have about four old cranks kicking around the
garage
showing that the No. 2 rod bearing spun. I believe that the No. 3 rod broke
once
without causing any damage to the crank.

well, opening it up to the new diameter of the hole from the gallery to that
main.>>
Are you cross drilling the crank? I use to do this and also drill a slightly
larger hole in the bearing. I haven't done this for a while since some of
the faster racers were not doing this.
