Well Russ, It looks like I'll have to do what you did with the linkage arms. while mine are solid with no signs of breaking up, the threads for the setscrews are mostly stripped out. this radio was worked on previously and the shafts jimmied up a bit to hold without the set screw. One was completely missing. I suppose I could drill and tap but I'm afraid the pot metal won't hold up. Plus, the thickness of the casting is only thick enough to get maybe 3 or 4 threads engaged. Hopefully I can improve a bit on the original design. As you pointed out on your Grebe, precision here is paramount for smooth operation of the 4 tuning caps. It's an interesting setup.
What did you use as the foundation of your new linkage? it looks like you may have used an L bracket that you bent and drilled. I'm picturing a piece of strap that I would bend and put the setscrew on the end instead of the side.
