Default Re: 2-piece blanks

I couldn't agree more. If you need convenience, can't tell the difference in action or fishability between a 4 piece and a 2 piece rod, and are not concerned about potential ferrule problems, buy the 4 piece. I am just pointing out the types of problems that ferrules create and that more ferrules do nothing to improve the rod's action or fishability.

Here is the answer to a FAQ concerning ferrule wraps on

"Yes, you should make what is known as a "ferrule reinforcement wrap" on all ferrules, both the tip-over-butt style and the
spigot/plug style. Use A thread and wrap tightly for a length that is equal to roughly twice the diameter of the ferrule opening. Make sure to get the wrap close to the edge, within 1mm if possible, as this is were any split-out would begin."

Here is another regarding ferrules from Rodmaker Magazine:

"The wrap tension on a ferrule reinforcement wrap should be a fair bit more snug than on a guide wrap. The idea here is to provide a bit of hoop strength for the ferrule, and to prevent a split out from occuring at the edge of the ferrule. Although most manufacturers include some sort of reinforcement wrap on this critical juncture, most also continue to recommend that a thread reinforcement wrap be made as well, regardless of the type ferrule used. On tip-over-butt ferrules or butt-into-tip types, the female ferrule requires a wrap. On spigot (plug) ferrules, both the male and female ferrules should be wrapped.

To make things a bit easier for you, I would suggest starting your wrap away from the ferrule edge and wrapping towards that edge. You may need to insert the but/tip section into the ferrule opening in order to support the open end of the ferrule. Make the insertion depth before wrapping and take care that your wrapping tension is not so tight as to constrict the female ferrule opening to the point where you cannot fully seat the ferrule.

Make sure to wrap almost to the very edge of the ferrule, at least within 1mm to 2mm, since split-outs start at the very edge. Many builders debate how long the wraps should be, and in my opinion, most make the reinforcement wraps much too long. For years I settled on a formula having the length being twice the outside diameter at the ferrule opening and have an absolutely zero failure rate at the ferrule. If you do not feel comfortable with this, I suggest calling the manufacturer of your particular blank and asking for their recommendation as to the ferrule reinforcement wrap length which should be used.

I would also like to make a suggestion to any of the blank manufacturers who do not indicated such in or on their blank packaging, to kindly instruct the builder as to whether or not such a reinforcement wrap is necessary, and how long it should be. Doing so might help prevent many failed blanks from being returned for replacement. ~ Tom Kirkman"
