Flute Head Cork Replacement

はじめに

When flutes age, or are taken back and forth between places with different temperatures and humidities, the head joint cork can become shrunken and loose, which will not provide an adequate seal on the instrument. If the cork does become loose, a new one needs to be properly attached to the crown and screw device and pushed into the head joint of the flute. Without this cork, the instrument is not able to be played.

Drop the new cork and screw set up screw first into the bottom of the head joint. If the cork is the correct diameter you should be able to see it partially through the embouchure hole.
Flute head joints have a tapered diameter that is smaller at the top. This will not work if the cork is put into the top of the head joint.
Use the flute tuning rod to push the cork into the head joint until the tuning line at the bottom of the rod is in the middle of the embouchure hole.
If the cork is difficult to push down, paraffin wax can be rubbed onto the cork to help lubricate it.
