Decided to start on the tuner. Was able to fill in the groove on one end of the shaft by brazing it. I didn't fill the groove left by the retainer spring. That gets closer to the plates. That takes a lot of heat and I had a hard time keeping the solder on the nearest plates from melting. You can see some roughness in the solder where it started to flow. After brazing the groove, I turned it down on the lathe. There was no way I was going to be able to braze the tuning knob end as the normal groove is deep. I filled that with silver solder and turned it down in the lathe. I don't know how long the silver solder will hold up, but it's better than it was.
I carefully sanded the knife edge off with a dremel tool. I tried to straighten the edge as best I could from the former "repairs". Thankfully, I didn't have to add any metal. The spring loaded friction wheel still worked on the new edge. It's not perfectly smooth because I couldn't get all of the bends out of the metal. Pretty good, though. I'm pleased it works as well as it does.
Oh, and yes, it is painted so that it will match the chassis as that will have to be painted because of all the rust.
