Welcome back to Red Wing MN! Hope you all had a fantastic holiday season because we're back in the swing of things here. This week in the brass lab we began with some review on dent work and soldering, along with some new tools and lathe work.
First off this week, we began my modifying a standard solder clip to create a draw knob installer. On many of the smaller crooks, the draw knobs do not have flanges on the bottom to hold on to while soldering. This clip allows us to hold the knob firmly in place while soldering. We began by shaping a steel bit into a shallow cup with a beveled back. We then increased the tension on the clip to hold the cup properly. Finally, we silver soldered the cup in place and pickled it. Simple and effective.
Throughout the week we've been working on a cornet bell in preparation for job interview bench tests. So far this has included soldering a supporting brace on the tail, soldering a patch onto the stem, removing dents from the bow, stem and flare and removing a bell fold.
We began working on aligning fast slides on intermediate and professional trumpets. This involved removing dents and lapping the tubes to make sure they fit. Then by flexing the first and third slide tubes, we aligned them to move as quickly as possible.
Finally this week, we worked on a lathe project. We turned these plates into a rotor bearing plate burnisher. These blanks were made by the machining class in Winona. We then faced them and drilled a hole in the center. We then drilled a counter bore in the center and tapped the hole. This simple tool will allow us to burnish french horn rotor bearing plates to friction fit after they have worn.
