I miss not having the discovery channel...one of the shows I loved watching was How It's Made. But then that's what youtube.com is for!
So, while prepping technique samples for my Metal Forming class, I thought I'd check out youtube to see what related video I could find and this led me to the episode of How It's Made about making trombones. Absolutely fascinating...especially how easy they make it look! There's a few tools there I wouldn't mind getting my hands on! Enjoy!
