Fly Rods Ferrules – Things to Know.

Fly Rods Ferrules – Things to Know:  Nowadays two types of fly rod ferrules dominate the modern marketplace – the “tip-over-butt” ferrule,  and the “spigot” ferrule, sometimes referred to as the “internal-spigot” ferrule.  (The metal ferrules used for bamboo fly rods are not part of this discussion.)

Some History: Both the “tip-over-butt” ferrule and the “spigot “ferrule were born in California over 50 years ago. Credit for the “tip-over-butt” design goes to Jim Green, who developed it in the early 1960’s while working for FenwickFenwick then patented it as the Feralite Ferrule in 1962. Their patent ran nearly 20 years. After that, the “tip-over-butt” design became a free-for-all. The origin  of the “spigot” ferrules, however, is far less clear. The only mention of their source comes to us from the late Tom Morgan, one time owner of the Winston Rod Company. In an interview Tom says the best he could discover the “spigot” ferrule was created by John Tarantino (A World Champion Fly Caster) in collaboration with  the JK Fisher rod company. We’ll have to leave it at that.

Given that both ferrules have survived this long you can be assured of two thing – When assembled correctly (more on that later) both work well, and neither one is so vastly superior it has run the other guy out of town.

“Tip-over-Butt” This style of ferrule is perhaps the most common. And it does require a bit less care and maintenance. As things wear the tip section creeps down over the butt making this ferrule somewhat self-adjusting. In its earliest days, this style ferrule tended to stiffen a rod. (sometimes to the manufactures liking) This was especially true if the manufacture added a reinforced sleeve on the female side of the ferrule, something rarely seen today. Advances in rod building methods have  eliminated any need to strengthen this style ferrule with added bulk. And the rods are not necessarily stiffer than a “spigot” ferrule rod.

“Spigot Ferrule” This ferrule is a bit more of a mystery to anglers, especially those who have never used one. Two rod sections are joined with dowel (spigot) securely glued into the lower rod section. Typically the spigot is made of fiberglass. When properly assembled the two rod sections do not meet, but are separated by upwards of 1/2″. Advocates of this ferrule say it offers you a smoother rod action. In other words regardless of the number of sections, the action tends to flow seamlessly along the blank offering the feel of a one-piece rod blank.

As a spigot ferrule wears the gap between sections is reduced. When the gap reaches 1/8″ you may want to sent it back to the manufacturer to be tightened. (modern spigot ferrules wear very slowly and should be fine for ten or more years. By the way, tightening the ferrule is a simple job for any competent rod builder.) As an alternate, a very light coat of wax can be applied to the spigot. (In fact some manufactures advise wax as a general preventive with even the tip-over-butt style ferrules. And I hear that cane rod experts use a touch of Ivory soap to lube their metal ferrules. ) It increases the spigot diameter and thereby increase the gap. (In my vest, I used to carry a small piece of a candle wrapped in aluminum foil. It worked fine if a problem arose in the field.)

Correctly Assembling these Ferrules: A surprising number of anglers fail to properly assemble a ferrule. You do not simple line up the guides on both sections and push the ferrule together. While this may work for awhile, sooner or later the two section will loosen during casting. This can cause the sections to fly apart or in a worse case scenario crack the blank.

The correct way is to align the two rod sections so the guides on one section are a quarter turn from lined up with the other section  (90 degrees out)) Push the ferrule together and then slowly and gently twist the rod until the guides properly line up. (Never attempt this with a metal ferrule!)

Number of Ferrules on a Rod: Once upon a time fly rods were pretty much all two-piece, with the exception being a few three-piece rods. Typically these three-piece rods were either cane rods or some high-end fiberglass rods. For example most of my Winston “glass” rods are three-piece. But times have changed. Now we have many four-piece rods. They are very convenient, although the upper most ferrule has a fairly thin diameter and may require more care.

Truth is I prefer the older three-piece design for two reasons. First there was never a ferrule in the dead center of the rod blank. So in my opinion the rod flexed better. Second, the upper ferrule was beefier and less prone to damage or wear. The only downside to the three-piece rod was this – while it fit overhead in most commercial jets, it could be too long for some small single engine bush planes.

Fixing a Stuck Ferrule: Now for a word of warning. If a rod is left assembled for a prolonged period time, the ferrule may get stuck and refuse to let go. In my experience a “tip-over-butt” is more prone then a “spigot”. Do not use brute force to separate the sections.  Here is a better solution.

Hope I’ve answered any questions you had about the modern fly rod ferrule

    Good info. Never encountered a spigot set up’
    Lefty Kreh advised rubbing paraffin/candle wax on the male section and gently screwing on the female section. I try to unscrew wit in the opposite direction when disassembling.

    Once had two sections horribly stuck together. Tried icing the male section and heating the female section. Did not work.

    What did work was to get a roll of electric tape. Wound half about an inch above the ferrule the half below. What this did was to give me more leverage. Ted

      Hey Ted,
      We are very fortunate to have should good ferrules nowadays, permitting fine multi-piece rods. My first fly rod was solid glass and had a metal ferrule that didn’t last long.
      There are two other known methods of separating a stuck ferrule. In both cases, the trick is to draw the sections apart in a dead straight line, as any bend you make in the rod will only tighten the ferrule. One method involves placing the ferrule behind you about knee high, and then pulling with both hands. The other method requires two people and is more than I can describe here. Yes a small amount of wax is a help. But if you’re in the field and have none try this: rub the male ferrule alongside your nose. There is typically enough oil on your skin to assist the ferrule.
