U channel - good thought!  Right now I'm working on bending brass strap.  I hope to make that work.  But if it doesn't, I'll look into the channel idea.

I was curious about the solder as my Grebe used (or at least does now) 10/32 screws and nuts, which is the way I'm going to do it.  I'm not sure how many modifications were made in the past.

All of my tuning caps rotate very easily so I'm hoping for a smooth system.  This reciever does not have a course and fine tuning system, but there is a friction wheel that turns inside the tuning dial. It looks like it could be the same as your fine tuning system. I'm a little concerned about the amount of friction that is there to turn the entire assembly. the AC Six, though, only has 4 tuning caps, so that may be a help compared to your 5.

By the way, where did you get the brown cloth sleve for the wire bundle?

Thanks for your help!
