Stuck Ferrule (female end) question

One thing we have not considered is that the male and female ferrules
are made of different material. Rod blanks are made in one piece and
then cut into sections. Male ferrules are part of the blank and
female furrules are laid up on the exterior of the blank. The two
materials while they are the "same" could have different coefficients
of thermal expansion. The expoxy, resins and fiber used to make the
female ferrule could be different than those used to make the blank.
That could explain what you experienced in very cold water.

That's a good point. In that scenario, the female ferrule would have a
larger coefficient of expansion than the male ferrule (it would shrink
faster when cooled). Which is a good design, if you think about it. In
the opposite case the rod would tend to come apart whenever it got cold.
