Starting 37-116 Deluxe Restoration
#32

While waiting for some help on the electrical issues (I know I need to provide more symptoms and voltage readings for anyone to start giving suggestions - I just needed to walk away from the electrical side of the radio after such a let down), I decided to tackle some mechanical issues.

The first was the dial hub that was not always rotating with the vernier drive and tuning capacitor.  I was getting ready to  disassemble the veneer drive to see if there was an issue in there, when I looked down between the metal plates.  i noticed this seemed to be the area where the slipping was occurring.  I stuck an allen wrench in this set screw, and sure enough, i was able to tighten it a little.  Now the dial hub is moving with the veneer drive.
   

The second issue was to tackle the old dried up flex coupling.  The rubber was stiff and cracking:
   

I followed Mondial's guide on the Phorum on creating a new one.  Minus the saving the brass rivets, cutting new rivets on a lathe, and using a punch to cut the holes.  I opted for a couple #8 screws (3/8" to replace the brass eyelets, 1" to replace the steel rivets), washers, and nuts.  I just used the Dremel to grind away the lip on one end of the rivit, and they popped out with a punch.  Then I traced out a 2" circle and in it, a 7/8" circle.  I cut the 2" circle with scissors, and the inner circle with an exacto knife. Then I drilled the screw/rivet holes with a 3/16" drill bit.
   

It's not nearly as pretty as Mondial's, but it gets the job done witht he tools and skills I had at hand.

So, now back to collecting readings and symptoms.  At least now I can reattach the tower and mask/dial scales, so I can see what I'm tuning to.
