 Replacement for a cracked tenon?
Author: Dan Shusta

While searching for tenon covers, I came across this item:

https://www.jlsmithco.com/product/hard-rubber-tenon-sleeve/

Is this old news?

What do you think of it?

It's more for making a loose or wobbly tenon a better fit than repairing a cracked tenon.

That's a good thing to have as an off-the-shelf thing as all too often, the middle tenons on many clarinets are wobbly. With this tenon sleeve you can achieve a perfect wobble-free fit (even without the tenon cork in place) and no risk of the tenon binding in the socket as it's made of ebonite.

And what's $20 when making them from scratch (machining them from solid ebonite rod) will take more time and effort to do? It definitely gets two thumbs up from me.

As far as tenon covers go, you can modify (by opening the inside diameter) oboe lower joint tenon covers to fit clarinet mouthpiece and both top joint tenons and a cor anglais lower joint one for a clarinet lower joint tenon. Most oboe makers sell them in either wood or plastic, or you might find some Chinese ones on you-know-where COUGHeBaySPLUTTER.

These are used to repair a clarinet tenon that has had the corners rounded off. Usually happens when it's taken apart over and over again and pulled at an angle. The original tenon has to be machined down on a lathe and have the sleeve fit over it and epoxied on.

Music Medic has a video of TB winds doing this repair.

I don't think it's new per say but I'm not sure how long someone has made a ready-to-fit piece to do it.

If you are just looking to repair a cracked tenon as the title suggests this isn't the correct thing for the repair.

Rounded off tenons are usually the result of incompetent 'repairers' who are overly slap-dash when it comes to sanding freshly fitted tenon corks, or by players who do a bit of DIY and decide to sand the tenon corks down themselves after watching YouTube videos of incompetent 'repairers' (and even some apparent 'pros') if they're a tight fit and end up sanding down the wooden tenon rings as well.

Wooden tenon rings rarely ever wear out through normal use, even after many decades.
