Acceptable filler for stem repair?

[nuclearfishin]

I have an amphora i restored from an estate sale, I really like the pipe but there's a hole in the stem that needs repair. What's an acceptable filler for vulvanite? I have black CA but that seems like it shouldn't go in your mouth. I also have a black clay I use in guitar making but I'm not sure if that will bond with the vulcanite. Any recommendations? Here are some pics of the before and after.

Reborn Pipes uses CA glue to repair holes.

The hole is in a location on the stem that will go in your mouth--so CA is ok?

Yup. Unbelievable how hard that stuff gets. I mean, don't chew on it, but it's otherwise safe.

I got a little dot of it on the side of my Kindle, and have been picking at it for weeks with no result. Look at a few of Steve's posts where he used the technique to see how it's done.

Can’t see the hole, but CA is fine.
I’ve fixed a few with it and it is serviceable, but can crack later down the line depending on what kind of a fix it was. Will show up as vulcanite ages/oxidizes.
G flex epoxy is what some of the best guys in the biz use-has more “give” to it.

Sounds like the hole's right by the button. Probably a tooth mark that has worn out. Nope, I don't do repairs on my. I'll probably ruin it with my luck.

CA can fall off. There’s better ways to do it. Maybe @georged can tell you what to use.
