Are you wrapping to protect the stent or for some other reason? The only problem I see is that the wrap will get in the way of the tip coming down. Just like a spiggot, the male section of a tip over butt ferrule will wear and the tip will come down a bit further. If the wrap is in the way, that would be bad.

I have no personal experience with that. I've had the factory replace a section for me. I had to send the rod in and they fit the third section on a 4pc blank. It turned out great. I can't imagine doing this sort of patch on a rod I'm going to use for a long time. Decent graphite blanks are just too cheap, and real high end blanks won't be the same after the fix (and are worth having a new section made)

Are you wanting to wrap it just below the point the female seats to? And is the purpose to reinforce the blanks around the lower end of the inserted stent? I don't see any harm in that; it is, essentially, the same that is done around a spigot. Just be sure to leave enough of the male exposed for the female to seat.

That said, I would call that rod an experiment, and I doubt it will fix the problem for long. Something else in rod handling or assembly of the ferrule is causing the repeated breakage. Identify that problem and make a change or it will be repeated, if not with that rod, another. If you wind up replacing that rod--as Carl said--graphite blanks are a dime a dozen--you don't want to repeat the problem.

Remember that ferrules of this type are not to be push fit with continuous pressure as in cylindrical metal ferrules. They are elongated conical mating surfaces that maintain the connection between sections by mild friction over a large area. Lightly slide the one over the over. Push snug. No forcing.

If you batter your tackle around or cast herky jerky or with a twist or cant, check for snugness as a habit, let's say each time you reel up completely, light a cigar, or whatever fishing habit comes at 20 minute intervals.

WT,
Let us know how it works out.

Time to be on the lookout for a new blank. It's not worth the effort, and if you are using this to march in, it definitely isn't worth going in with a rod that is suspect.

Was this originally a custom build? I am wondering if that female ferrule was wrapped to tightly to begin with. I have a rod that always comes undone at the same ferrule every time. I suspect that I wrapped that ferrule too tightly, but it might just be that blank. It was a blem.

Being a natural tinkerer, this is right up my alley. I think I have corrected the problem and the ferules seat well now so this pack rod will go back in rotation. I am not going to put a wrap on the male ferule.

I know its graphite, but it has a good flexing action that I appreciate.

I always carry a backup since I am prone to break my rods, at least when they are graphite.

Thanks all for your help.
