Staying with the changer...what I consider the heart of the pedal steel guitar. Refer back to a previous photo where you see the endplate with the window in it..the brass "fingers" where the string comes thru a drilled out hole in the finger and then up and over the curve, then below, the raise and lower bars, the ones with 3 holes in each, to enable "Triple raise and triple lower" on each string. The pull rods come out thru those holes and each have the nylon tuning nut.
First, a detail view of the brass finger
Then, an exploded view of the changer mechanism, which is made up of the brass "string finger", the raise bar and the lower bar you will see the holes drilled thru both bars or plates. They are held together here with a rivetand this creates the pivot point so that you pull the raise bar to raise a string, as well as you pull the lower bar to lower a string. This type of changer is called an All Pull changer, as opposed to the old push-pull.
