Yep, got same thing on my bipod legs for my weapons, but not sure thats the sort of thing Lewis needs.

So you'd be talking of a grip of 15 to 16 inches . I would have envisaged a sort of full wells with an even (ie no taper) section where the reel seat was intended to slide. I certainly wouldn't want to move the reel seat with a fish on! Don't think I'd in any way thought this thro but rather as a springboard for other ideas. One thought, some people go on about having a reel that balances a rod - this could be used in that context.

Looks ajustable. How you adapt it would be interesting. I didn't spend too much time on the link but might be of use.

One of the Daiwa switch rods had an extension as you describe ( New Era I think) . Might be worth giving them an email

Thanks for all your thoughts, folks. For a start I'm pleased that no one seems to think it a daft idea!
I'm currently thinking that the twist-lock idea is the way to go. Being able to infinitely adjust would be a big plus and, as o.c. says, one could 'tune' the extension to suit different reels' effect on rod balance in the hand, depending on their weight. For this reason, and because the excess weight will be behind the top hand, I wonder if the gizmo's added weight might be a benefit rather than a negative. It could also be an advantage on a loch-come-river salmon rod where an extension is a pain in the boat until actually needed. But, if you leave the boat for the bank or the river then converting the rod to d-h with just a twist of the wrist could be a great asset.
icejohn - Thanks for that link. I knew I'd seen something along the lines of what I want and that Rodhouse thing was it, but I don't think that's it is designed to take a lower cork grip which a Switch would benefit from and may be specific to a particular spinning rod reel seat. It's hard to work out how it functions from the pics they give. Nice-looking bit of kit though!
Going back to the Manley 'Adjust-a-butt' JayP posted on p.1, as it's designed for spinning/coarse rods it is made to butt up against a section of cork handle. What I want would marry with the rear of the reel seat, so some form of collar might be required between seat and twist-lock mechanism, if only for aesthetics. Perhaps also to act as a stopping point for the twist-lock mech?
fruinfisher - Thanks for the lead with the New Era, I'll go and have a look online shortly.
Cheers all,

There’s a chance that there will be a youtube vid showing it
I've now taken my carbon tripod legs apart & report as follows: It's a clever design, the legs are parallel form carbon thin tubing. To inner leg has 2 holes near the top, into which inserts with raised circular pieces are pressed so as to leave a gap about ⅛" wide between their edges, and this prevents rotation against the outer tube because the outer tube has a ridge running lengthways along the inside of it. The screw cap on the inner leg has a plastic insert that interfaces with a conically shaped fitment at the end of the outer tube, and as the screw tightens it locks the plastic insert to the outside of the inner leg. Locking to release is about ¾ of a turn. If you could procure the tubing and screw mechanism it would be easily stiff enough for a fighting butt and to cast with, the tubing is really strong even though it's thin. I'll take some photos which explain the mechanism more easily I hope!
Pictures as promised: Inner tube with inserts attached - note the gap between the inserts for prevention of rotation. Inserts showing retaining circle.Conical holes in the outer tubing. Inner tuning with attachment holes. Inner tube screw, and 2nd shot showing the plastic spline for tightening agains the inner leg via the conical shape on the top of the outer tube. All very industrial stuff, and not really home workshop ready unless you can get all the bits.. However the locking mechanism is just what the doctor ordered. I'll look on the web to see is there is a way to make these that is less complex.

In Carbon, you need this - Infinitube. Expensive but proper compression joint, and the locking rings are also available. https://www.rockwestcomposites.com/...coping-compression-rings/cr-infinitubev-group

You're far beyond me with this, Jim, so I'm chancing my arm here but .....
Some walking poles use twist-locking mechanisms. Might it be possible to repurpose one and incorporate its clutch? It might be a cheaper option as such things are mass-produced in the East.

Just an opinion, that I hope you don’t mind me posting.
Personally I think the extension mechanism you are thinking of is not the most pleasing to the eye and is a bit gimmicky.
I totally agree with the practical aspect of having the ability to have an extension piece which has the ability to use a single handed rod as a double handed rod if required and I also fully agree with the importance of balancing the rod at the handle .
In the past I have built rods with an insert thread at the reel seat and made three different length extension of different weights (by using lead shot) insuring balance is uniform at all time ?
Okay you have to carry the extension with you, but they look neat and are fully functional grip wise.
Good luck with your project

Yep, good idea. they probably buy the carbon from the Americans! At least it's worth a try for a prototype & if it works offer it as an option.
One thing to think about is the strength of such an extension grip and its affect on the rod when in use.
I've seen many posts of people who have converted old single handed rods into a double handed by adding a long rear grip in either a fixed or removable way.
In both cases the strength of the butt end of the rod was compromised.
You'd have to design it in such a was as to not apply undue force to the end of blank when the handle is inserted and in use - a bottom handed spey cast often involves hitting/tapping the bottom hand against a hip or the stomach. Would the connection be able to stand this over long period?

Yes, Steve, I agree completely. I think that a fighting butt with a snug-fitting, tapered stent of about 5" or more is a better connection than the PacBay screw fitting adaptor some might use. That only extends to about and inch and a half into the blank.
With this idea I envisage one tube inserted and glued to about 5" inside the blank to spread the load. It'll be sitting under the reel seat so should be adding strength to the butt, not creating a stress point close to the blank's end. What the inner rod is made from I don't yet know ..... I'll leave that to a specialist.

I've just watched Hywell Morgan with the NewEra on YT and I'm afraid it has a separate screw-in butt. Thanks, though.
Edit: I've happened upon this discontinued Jensen 11 ft 'Cheetah' ''with extendable butt'', looking very much like what I'm thinking of - from a distance, unfortunately!

Looks the biz @Lewis Chessman. I wonder how long the extension handle is? Probably quite long, extending right through the reel seat and into the top butt, via a sleeve of sorts fixed to the blank or seat/handle?. I guess a shaft of solid fibreglass or graphite would be appropriate to prevent snap off at the point it enters the handle.
Looks neat! A shame it was discontinued.
