I don't know, but let's say it was the CHIMNEY that was broken? How successful are these type fixes? The following eBay auction raised some interest. I know about fixing chips and cracks in tone holes. I aslo have studied how to replace a tenon. However, I have never heard about replacing a chimney? How sucessfully has this been done; does anybody have any first-hand experience?

Mark,
If I can find the chip I just glue it back in place with Loctite 380 (Black Max) and haven't had a problem yet. When the chimney needs to be repalced I send it off to Carl Votaw. He has the tools to do it and unless you do several of these types of operations it isn't practicle to buy the tools necessary. Basically, the old chimney is drilled out and the wood is threaded for a new chimney that is threaded to match. A little expoxy is put on the threads for a lasting fix. Very similar to your tenon replacement.

Thatnks, John. NOW, what about voving that new "addition" ? My query centered around the Buffet ELITE Clarinet that is on eBay and has had a tone hole replacement, according to the ebay auction seller.
NOW, I don't want to buy this Clarinet --- I have played the model a couple of times; as we all know this is the top of the Buffet lineup.
Back to the question --- will there be a problem with TUNING the note after the addition of the (new) Chimney. Conceivably it could affect tuning on the entire clarinet, correct? (assume there could be some undercutting or ADDING of material where the bore meets the tone hole)
Thanks.

Mark,
Tone hole replacements can either be hard rubber or wood. I'm sure a clarinet of this level had the chimney replaced with wood. Hopefully it has the same height as the original, doesn't protrude into the bore, and yes, they can be undercut a little if necessary. Most often the integrity of tuning and tone quality are kept if done correctly.

It is not uncommon for clarinets to have the top part of the tone holes for ring keys to be glued-on extras. This makes the lathing of the body much easier and probably means less timber is wasted. It also means that the tone hole can be stronger with no short cross-grain.
I have mended broken tone holes by grafting in replacement timber or ebonite, without going near the undercutting, and without threading, for which I see no purpose.
I have also mended broken ring key tone holes much the same as a dentist builds up a broken tooth, with minute pins (for strength) embedded in a resin-based reconstruction. For me this method has not failed yet.
For chipped standard tone holes I use similar 'dentistry' but without pins.

They probably most easily break when a normally protective ring key is bent in an accident so that it exerts sideways force on the tone hole.
On Chinese clarinets they break very easily if a technician tries to remove glued ones which have leaks through the glue, which is very common with Chinese clarinets. They are usually (very brittle) hard rubber inserts.
