Howard, did you reinsert that pin that I mentioned using a magnet to extract? I believe it is what finally holds the whole assembly together!

I am not sure he could make the assembly stay together in the first place.

Wow morzh, you have access to some very useful doc.  That cross-section (Fig 2) is dynamite.

   

As you can see, if the ball wasn't attached to the vernier shaft, the shaft would simply back/fall out.  Which is exactly what happens to mine now.

Starting tomorrow I'm gonna start calling some of these local Boeing fab shops that do the small custom fabrications.  Even if they won't reattach it for me, they might tell me what the best method for doing so is.

Thanks.

Btw, here's a pic of a different '30s Philco radio fine tuning mech.  It's a different model but they used the same method for implementing vernier control.  Note the ball-end.

Hi Ron. Yes, I got it all back together the first time, after getting it all cleaned and lubed, and it was working really nice. It was while I was inserting the pin you refer to that holds the coarse shaft -- thus the entire assembly -- in place that the end-ball came off the vernier shaft.

I think that's the one I have in Philco 60, which I have recently fixed.
The last robodial radio repair (38-690) happened in 2017, and I simply forgot how I did that. I remember the pin did not want to come out.
But for the life of me I do not recall the ball at the end and what I did about it.
The end of the shaft then should be concave so the ball readily goes into it when glued.
