Brass class is flying by.  I am working on a french horn and a trombone right now.  There are separate pages for each, so be sure to look at those!  Things I have been learning include porting and stringing rotary valves, aligning trombone hand-slides, and taking dents out of trombone hand-slides.
I learned an important lesson with Greg (my instructor)  today.  The brace that goes from the Trombone bell to the gooseneck isn't always a solid piece.  It can be hollow, and if you chuck it in a soft jaw vise, you can crush it.  To fix it, we have to cut the tube, restore the area, and then solder it with a ferrule back on.  Since it was Greg's idea, he is going to help me fix it.
