Here is a typical bent bell stem that I show a partial repair on. The rest was done off camera with a time crunch. I didn't film it all but you get the idea.
Love watching these! I once saw a sales person (no kidding) drop a vintage Olds Ambassador cornet on the floor when he was pulling it off the wall hanger. It actually bounced a couple of times off the uncarpeted floor. Amazingly there was no damage. Those horns were bullet proof.
