    Well that approach didn't work. After calling my uncle he had me simply shorten the throw on the shorter cable and the problem went away completely. Both cables TIGHT throughout movement in both directions. I moved the lower cable up a half inch and done, no playing around with various servo...

    Offset servo idea by the step. A piece of G10 makes an excellent custom servo arm. No idea if this will work. There's the 1" +/- difference.

    Ordered some shoulder bolts from McMaster Carr, too heavy. I should have thought about nylon, which they had. Much lighter. However, the threaded wood inserts are military grade heavy and way too heavy. I think my cheap plastic bolt kit from the hardware store is my best option.
