CA Gel will work for ferrules, but 1. has to be gel 2. epoxy is still better. How thick was the clear gorilla glue?
If I'm not mistaken that is still a cyanoacrylate (CA). It needs to be gel mostly for the gap fill. Also, will need to sit sometimes for over an hour to cure.
There was once a poster here, I forgot who, whose signature line was "I build cues because I hate money". I don't know why but this post reminded me of him. A testament to the determination and patience it takes, I guess.
You are correct, it has not been produced for years. I was told that it was inconsistent, blotchy, unsellable and the manufacturer won't take returns.
They have something sort of close now but it will not match old construction.
Juma? Brittle? Hardly. You have it confused with something else. I believe it might not knurl but brittle? No chance. I put a rod in my lathe chuck and hit it with a hammer. I've dropped rods on end on concrete. Nothing.
Question for you Mike. Have you ever used the Elmer's clear school glue for linen wraps? I'm wondering how it compares to the white. I would imagine it would look as good or better, but I haven't gotten around to it yet.
