I picked a Yamaha bass clarinet off of our shelf that happened to be a little worse off than expected. One of the many issues that had to be fixed was a touch piece that had snapped due to previously being broken, and subsequently brazed back together.
Brazing broken keys is generally fine but in this particular instance, the joint was messy, and furthermore the two pieces did not fit together as intended. In order to guarantee a longer life for the instrument as well as a more comfortable playing experience, I elected to scrap the original pieces and make my own. I enjoy getting to make parts and it has been a while since I had the opportunity, so this was a welcome diversion from the norm.
