Large ferrules on an Edw. Barder rod.
By PHIL MONAHAN [MidCurrent] – In the old days (20 or 30 years ago), before advances in materials and design technologies, the main problem with sleeve-over ferrules was that they didn’t allow a continuous diameter or taper in the blank. The upper section had to flare dramatically to fit over the lower section and still have enough strength to withstand flexing, so there was often a significant difference in rod diameter from one inch below the ferrule to one inch above it. This led to some sloppy rod action and breakage problems. The internal ferrule, on the other hand, while more labor-intensive to build, allowed for a continuous diameter from below the ferrule to above because the upper section didn’t have to fit over the entire diameter of the section below it. With more consistent diameters and tapers, internal-ferrule rods provided smoother action.
However, the advent of high-tech graphite, new and stronger scrim materials, and modern design methods have allowed rod builders to create much slimmer, more efficient, and smoother sleeve-over ferrules—to the point that there are no longer any significant overall differences between rods constructed with each kind of ferrule.
