The Crack Why do clarinets crack? Sadly, there are several reasons why a clarinet can crack. Generator klyuchej dlya das xentry. Wood is hygroscopic.

This means that it can absorb and release moisture. If your clarinet absorbs this moisture unevenly (perhaps through not properly breaking in your clarinet when it was new or when picking it back up after a period of not using it), this can create a stress pressure that builds up in the wood and just like an earthquake, that pressure has to be released. With this clarinet, the student had not properly broken the instrument in when it was new and as a result, it cracked within 2 months. The instrument in question is a Leblanc but that has no bearing on whether it can crack.

As you can see, the crack is a wide crack that goes through 3 total tone holes (you can click the photo for a much larger version). This is no simple job. Before we can perform this repair, we clean the crack and joint to ensure that there is nothing that interferes with sealing the crack. We also will let the joint sit and dry slightly as the crack will close a little before we perform the repair.

Tone Hole Inserts When the crack goes through the tone hole, the only way to bring back it's integrity is with custom tone hole inserts. The original tone hole is cut out down to about 50% of the body. This leave the original undercutting shape in tact so that the performance of the clarinet when done is not affected by the insert. Depending on the severity of the crack, the tone hole inserts can be done before the full repair of the crack.

This ensures a nice tight fit of the insert as was done on this clarinet. As you can see in the photo, the top trill key tone hole has the insert installed and the next tone hole is bored out ready for it's insert to be installed. We custom make each tone hole insert from hard rubber in our shop. The hard rubber gives a material that is easily machined so that we can ensure the tone hole is made and fit well and also gives a material that has a weight very similar to wood so that tone is not affected.

Pinning and Sealing To properly seal the crack, we use a technique called 'pinning'. We insert metal pins into the body of the clarinet. These pins are carefully placed so that they do not enter the bore of the instrument. These pins will force the wood back together in to its original position. This ensures that the inner bore shape of the clarinet is restored and the performance of the clarinet will be returned to its original design. After the pins are inserted, the crack is sealed. The pin holes are then covered with Grenadilla dust and a Cyanoacrylate adhesive.
