Doh! Another tenon repair question.

[nortac]

Through great neglect and stupidity, I managed to snap off the tenon of my new Savinelli Clark's Favorite. The tenon itself is a black plastic insert glued into the lucite stem. It was very thin walled and the weak point that was obviously not designed to withstand the impact of a falling DVD player (don't ask). If I were to attempt to glue it back, would CA be as good as any other glue option? I wonder about potential toxicity of various glue options in a smoking piece. Any thoughts? Even if I were to obtain a replacement tenon insert, it would still have to be glued.

Pics would help to understand exactly what would be required. It would probably be better to get a replacement insert anyway though.

My camera is on the fritz at the moment and I doubt cell phone pics would do it justice. Bottom line is, it will have to be glued. So basically my question is, what's the best glue to use and what is the potential toxicity of using said glue in a smoking pipe where the hot smoke will make contact with the glued surface? It probably would be best to get a new tenon insert, but that will probably take some time and research, and may not be cost effective in the long run. In the meantime, I'll probably just try to re-glue the broken tenon, and if it doesn't work, then ship it off to a pipe repair entity.

The same noxious (and toxic) fumes that CA emits when curing will be released when the cured CA is heated.
The tenon shouldn't get that hot, but it could.

And other than CA, I can't think of anything that would be effective at reattaching the piece, especially if it is as thin as you describe. A glued joint (likely even CA) would not survive giving the stem a twist to remove for cleaning.

That about sums it up.

To add...

If the wall of the tenon is that thin, it sounds like the pipe was designed for a filter.
If you don't use a filter, replace the entire insert with one that is drilled to the same diameter as the hole in the stem itself.
Most Pete's are made like that. The tenon is large enough so that it CAN be drilled out for a filter.

Send it out to Walker's he'll be able to replace it with a delrin tenon and you'll be good as new.

I will attempt a CA repair myself. Yes, the pipe is designed for use with a filter, the triangular balsa filters. Also comes with an insert for when a filter is not desired. If all else fails, I will probably send of to WBW, as I have some others that I was going to send anyways.

Please don't.
When heated, it emits cyanide compounds.

 

[nortac]

Please don't.

Doh! Well that is the type of reply I was looking for with the original question posed, however it is a bit late, as I have already used the CA to effect a repair. Do you have an alternative suggestion? Assuming I can undo the damage.

 

[cb91710]

I mentioned it in my first response, I just wasn't specific on the compounds released, I just said "Toxic"
The tenon will need to be drilled out of the stem and replaced.

 

[nortac]

As fate would have it, the tenon repair with CA did not hold up, so off to WBW it will go with some other pipes that need repair and restoration.

+1. I have heard great things about Walker.
