You should break it MORE. Then drop it into cement. I was fiiddling around with the Christie's auction website to look up something completely unrelated, and I found this piece of art by Fernandez Arman, called "Saxophone." It sold for $71,394. (I can't find a bigger pic, but the horn is either an Evette-Schaeffer or one "borrowing" their patent: it's got the extra keys for C#/B/Bb above the D/E/F keys.)
You know it does cost good money to rent a steam roller. Techs have always said to rent a steam roller for certain instruments. I guess someone has actually gone and done it now ...
I've had instruments come in that were worse than that. Why, only last week....................................!
Why fix it? I'm sure the owner was playing sharp all the time. This process, of course, flattens it a bit
