This week was a short week here in Red Wing. Thanks to school meetings and Thanksgiving Holidays, we were in school for a total of two days. We used one of these days to have some fun on the lathe.
This week we made some tuba valve stems from scratch. We began with a 1/4" brass stock, turning it to length and threading one end. To ensure proper piston function and porting, the length of the stem body had to be precise. The stem was faced down to a specific length and drilled out. Finally, the stem was tapped, cleaned, and tested with its corresponding valve button.
In preparation for working on flutes, we made a flute screw board. The pattern was pasted onto a block of pine and holes were drilled out. Nothing fancy, but it works quite well. To end off the week, we were given flutes to practice nomenclature and maintenance on. This flute is an Artley student level flute. With a five day weekend ahead, we dive into the flute world next week.
As a last note, I have posted a page dedicated to the process of the Armstrong project clarinet. For more information, leave a comment or email me at airbandrepair@gmail.com.
