What Type of Adhesive to Use to Connect Tenon to Mouthpiece

[hoosierpipeguy]

I have several pipes where the tenon has separated from the mouthpiece. Haven't smoked them for awhile and assuming that is the cause. Not a big deal and it appears to be a simple repair. Just need to know what type of adhesive or epoxy I should use to repair this problem. Thanks in advance for your input.

Clear gorilla glue epoxy should be fine.

Just be aware that gluing the tenon is a temporary fix and will fail at some point. A permanent fix requires either an entire stem replacement, or drilling into the stem to anchor a replacement tenon into the stem, which works much better against sheering forces.

Just regular 5 minute two part epoxy. It’s lasted over a year and I figure if it does happen to fail it is very easy to do again.

NONE!

I'm curious as to what brand pipe has a tenon that can separate from the mouthpiece.

Chris Askwith makes his stems out of polyester and inserts a threaded Delrin tenon. I assume he uses some type of glue to secure it (see q-tip dabbed in)?

Not sure exactly what you mean. The tenon came out of the stem? The tenon broke off? How about a pic or two?

That looks threaded. If so, I'd thread it back on and then gently remove the tenant from the shank. Unscrew the male insert. Put a couple drops of super glue on the threads and reinsert it, but make sure it's clock, right

Try twisting the stem on clockwise. See if it holds enough to twist it apart. Threaded in tenons always require clockwise twisting. Elsewise you unscrew the tenon. If the tenon does not thread onto the stem, twist it out with a pliers and use a dab of epoxy to seat it in the stem. Wipe off any excess.

Neither one will screw in. I'm going to use a pliers to remove the tenon, screw the tenon into the mouthpiece and reinforce with a little epoxy. Thanks.

I recently got a wood lathe from a buddy.
Upon researching what I can aspire do with it, I was amazed how many folks I came across that use them to mortise the shank and the stem and join them with a Delrin tenon glued to the stem side.

Thats the same way 9mm pipes are made. They are secured in the stem with epoxy. My Viprati snapped out of the stem once and a pipe maker told me to clean it, put on a thin coat of epoxy and be happy. Its been as good as new since. Sometimes a glue joint just decides to fail

There are a lot of people who don’t want to spend the time, focus and patience to make a properly fitted, integrated tenon as part of their stem. Unfortunately.

Especially when they can buy a bag of delrin inserts ready to go and all they have to do is drill 2 holes.

Reportedly, delrin tenons don't wear like Vulcanite.
Here's a related glue thread. The maker of the tenon isn't named.

I do remember reading that thread before. I used to glue my own tenons for my own pipes when I didn't have a lathe and I had 1 or 2 fail. Between that experience and reading few threads like the one you posted, I immediately got a lathe and stopped the practice.

I simply don't believe in glue/epoxy being used for structural integrity anymore when there's legitimate alternatives (integrated tenon). I think at a minimum if someone wants to use inserts, they should use some form of mechanical backup like real threads or a post that runs through it all crosswise.

I think it's a big disservice to not do so, but that's just my opinion!

I recently fell into a wood lathe, so of course I’ll be trying my hand at pipes. I’ll probably do a Delrin tenon, as I think a hand cut ebonite stem with one will be better than a molded vulcanite stem fitted without good tools overall.
I’d get a tenon cutting tool, but I see money going to pipe jaws and buffing tools first.

I think it’s a totally fine way to start out as you work through your skill levels and comfort.
