During this short week, we continued to experiment with the lathe and making small hand tools. This week’s lathe project was a Rotor Bearing Plate Seater to be used in the second semester. Using the lathe, we faced each end of a length of 1” PVC. We then drilled a 0.413” hole, ½” into the PVC. Thus a tool is born.
We continued working on our trumpet bells. Using a ¼” brass rod, we soft-soldered a brace from the bell stem to the bell tail to support the tail while we work. We continued to buff the bell to prepare it to receive soldered patches.
We created a slightly more complicated tool this week. Using a ¼” steel rod, we created a Double Ended Bench Crook Rod. This involved filing a taper on each end of the rod, bending each end to a specific angel, silver-soldering a ball on each end, and preparing each end with a pickle and buff. This tool will allow us to reach dents in the crooks of each slide of a trumpet.
Continuing with crook dents, we explored removing some dents in the second slide crook. This gave me an opportunity to continue work on my Lignatone trumpet, as the second slide was dented so badly that the draw knob popped off. This dent proved to be quite a challenge, but I restored the crook to shape. With a buff, and a new draw knob, it will be good as new.
