Reducing a Mouthpiece Shank Bore

October 2012 If you want to use several different mouthpieces on your sax, and a few of them fit loose, what can you do? You could put a larger neck cork on your sax, but then your other mouthpieces will be too tight. You can temporarily wrap paper or Teflon tape around the cork. But for a more permanent fix, I show how I use epoxy to make the mouthpiece shank bore smaller. See MojoMouthpieceWork.com
