And a glorious, good day to all!
Has anyone seen, heard of or made a combination ferrule with both an external tube and an internal spigot as well, for a multi piece rod? While the tip-over-butt is the norm these days, yester-years saw metal external ferrules and solid FG spigot ferrules. I just have an inquiring mind and would like to know.

The modern tip-over-but ferrule is a superior design. It costs a bit more at the outset because you are basically creating two separate rod blanks rather than taking a single one and just cutting it in half and installing a ferrule.

There is really no reason to have a ferrule that is both over and inner. The idea isn't to make the ferrule stronger than the surrounding rod blank, but to have a junction that shares the rod's overall characteristics at that point. Ferrules need to flex, which the modern ones tend to do quite well.

Tom,
Thank you for responding. Your comments and insight are always welcome and respected, even desired. I certainly agree the tip-over-butt is, arguably, the best of the three ferrule connections presently employed by the manufacturers. However, it is impossible for the rod builder to duplicate when producing a multi-piece from a one piece blank and our only alternatives has been to utilize an external or spigot ferrule. While most would agree an external is rather archaic and upsets the natural flex of a blank more than the other two, but simple to produce, there are those who would argue the more labor intensive spigot ferrule may be superior to the tip-over-butt regarding rod flex. The larger diameter external ferrule is typically stiffer and more durable than the more flexible yet more fragile spigot.
In my need to produce multi-piece rods from single-piece FG blanks, my habitual “Over-Thinking” utilized my structural composite knowledge in an attempt to engineer a better rod connection which could be fabricated by any rod builder. I have basically inverted the “composite sandwich” theory to produce a ferrule system which is flexible, strong and light. A composite sandwich utilizes a lightweight core of foam, balsa wood, Nomex or aluminum honeycomb bonded between two composite fabric skins to produce a piece which is extremely strong and stiff while remaining extraordinarily lightweight. I have inverted that by skinning the rather rigid rod blank with thin, flexible inner and outer FG tubes which work in conjunction with each other and the blank as well to continue the flex of the blank through the ferrule. The blank itself is utilized as a mold or buck to produce the ferrules with inherently identical tapers. Total weight of the inner and outer FG ferrules is 2g verses the 9g of a similar size aluminum ferrule. Rough static testing side-by-side with an identical 7ft blank revealed a difference of the flex curve to be less the 0.187in.
After some trial and error and refinement, I have one ferrule system ready to be tested. Dang, I guess I’ll have to go fishing. I will keep you posted.

By using a lower modulus material to make the over-sleeve, the external tip-over-butt section can closely match the characteristics of the rod blank at that point. Please consult our article on making ferrules for the specifics.

You are well informed and precisely correct.

Interesting, but find very little application! I guess if one had some one piece rods or blanks not getting used due to length, it would apply. I cannot see one buying one piece to make them multiple piece.

Phil,
There is no need to acquire and chop-up an additional blank. I am fabricating the external and internal spigot ferrules from bi-axial woven FG sleeves and structural epoxy utilizing the blank itself as a mold or buck which inherently transfers the identical taper of the blank to the ferrules.

Phil,
Excuse me. Sorry for the misunderstanding. Reading your reply a second time made me realize you meant buying a one piece blank to make a multi piece rod rather than just buying the multi piece blank in the first place. You are correct, I agree with you and I will every chance I get. However, I am dealing with one piece, new-old-stock (NOS) vintage FG blanks and do not have the option, plus other old two piece rods incorporate an old, metal external ferrule which do not perform as well while being 0.25oz heaver.
