How to Make A Trombone (Discovery Channel)

Yay to the Internet – I would have definitely not seen this otherwise 🙂 Here’s Discovery Channel’s 5 minute take on how to make a trombone, specifically some custom made Shires Trombone. I wonder if the rest (Bach, GreenHoe, Edwards, etc.) are made the same way? Or more factory like?

From the looks of it, the “art” is still in the bell section. The rest seems to be a standard formula that depend on the material used. Unless the guy screws up during soldering or putting the wrong balls in the tube etc.

One thing I don’t understand is why the freezing of the tubes actually _help_ the bending of the various tubes. I thought it would become hard and crispy (what’s the word??) and would break! Alas, I only know about the blow job 😉
