During this week, we continued working with soft soldering. We practiced making diamond patches and soldering them onto the bell stem. Later in the week, we were tested on this same process.
Continuing with dent work, we looked at taking out bell folds using universal mandrels and dent rollers. Because the mandrels are universal, they do not perfectly match the shape of every bell and so much of the rim straightening had to be done by eye with a small hammer.
We also continued to work on small slide assemblies. First, we were tested on removing dents from the second crook. After that, we constructed first slide assemblies from scratch. This involved soldering ferrules onto the inner tubes, then fitting the tubes to the crook while in the trumpet. After a buff, the parts looked factory made.
The highlight of this week was getting our project trumpets. These trumpets come from actual clients who want work done. They are in various conditions with numerous problems. The trumpet I received is a Reynolds trumpet from 1964. Below are pictures of some of the work that must be done to it. Needless to say, it may take a while.
