Saxophone Repair Topic: Conn Pivot Screw Lock Screws

Saxophone repairman Matt Stohrer of http://www.StohrerMusic.com walks you through the function and use of the sometimes confusing and always tiny locking screw mechanism of vintage Conn saxophone (and some other instruments) pivot screws. Note that the example used in this video is freshly overhauled & lubricated so I don't lube it again on screen- don't forget to clean and lubricate as shown in my video "Saxophone Repair Topic: Changing The Oil"
