Hello, Well, I was cleaning the trumpet that my high school has let me use for band, but when I was cleaning it something broke. It was attached then when I looked at it again and it was detached from the bell pipe(I think that's what it's called? the part where the pipe is opening into the bell). The small thin piece of metal attaching the lead pipe to the bell pipe broke right where it would be attached(basically right where the metal was melted to attach it to the lead pipe). So my question is, would it be ok to use a bit of glue to reattach it until I can bring it in to be repaired? And how does anyone know around how much it would cost to repair it(just an estimate, please?)?
