Gluing a 2-Piece Rod

[Knot Sure]

If I glue a 2-piece rod together (well), is the sensitivity similar to a 1 piece rod?  Or, does it just increase it some or not at all? (Not necessarily an upper Taney question, but lots of expertise here). Thanks for any input.

Is the ferrule glass or metal?

imo, no.  The ferule will still be there, it just won't come apart or twist out of position.  The sensitivity is designed into the taper of the mandrel and the thickness of the layup when making the rod. An exception might be if the ferule is very worn and loose.  If the rod is tip over butt the two pieces  were made on different mandrels to begin with and never were a single taper.  This is just opinion, I have never actually glued ferules, though I have thought of it concerning 4 & 5 piece fly rods, just to eliminate the aggravation of jacking with so many parts. I have used rods that were left together for so long that the ferules stuck.

Everybody has this perception that graphite fibers transmit signals like fiber-optic cable.  It doesn't work that way.  That is not what makes a rod "sensitive".   Weight/balance/stiffness is what makes rods transmit subtle bites better.  A one piece rod is no more "sensitive" than a 4 piece rod if weight/balance/stiffness is the same.

By stiffness I mean....how quickly the blank recovers from a bend.

Is this a fly rod?

If there is a ferrule there will be more mass in that area relative to the rest of the rod.  If you did a deflection test I’m sure there would be some “flattening” in that area.  

I have cast hundreds of rods and I couldn’t tell you what makes a sweetheart.    I fish a 4 piece currently over a two piece I swore would never be beat.  But it was.

Thanks for all the input. Very informative. And, to answer Dutch, this case would be glass ferrules, but it sounds like there is much more to the question than making a solid contact than what I had thought.
