Broken clarinet tenons are actually quite common. This Selmer is a great example.
Wooden tenons are much harder to repair than plastic ones. In this case the area was cleaned, a wooden patch was shaped and inserted and was finished with filler. This method is much more reliable than most traditional ones.
A Bari Sax came into our shop and had MASKING TAPE over the high E tone hole. The key was missing and it wasn't a common brand so finding a replacement wasn't an option. Pictured here are the parts used to make a new key. 1. nickel rod 2. A high D# key from a tenor sax 3. A side C lever from a tenor sax.
The High D# key was bent to fit the horn and meet the tone hole.
Then it was cut and silver soldered or brazed to the nickel rod.
The paddle was cut from the side C lever and added to the nickel rod. Pivot screw holes were drilled at each end of the key.
Here's the finished key(on the left) next to it's neighbouring F# Key.
