How far above the ferrule ??
A rod with a clean break is a fairly easy fix
A shatter is another story.
Too close to the ferrule might be tuff also
To fix a clean break, a piece of scrap fiberglass blank needs to be fitted into the break, much making like a spigot ferrule, and glued together.
Then the whole area is overwrapped and finished.
I fixed one of my own rods like this recently... like I said.. easy
The simpler the outfit, the more skill it takes to manage it, and the more pleasure one gets in his achievements.
