I could easily use aluminum, and probably should. Afterall, if I used the airframe as ground it would obviously be aluminum.
Appreciate the comments. Helps to refine my project. And prevents tunnel vision.

Nicely done and the more you develope it the better it gets.
FWIW I bought a grounding block from B&C Specialities (forrest of tabs) with 24 connections on it and found out that I needed more than that. Of course I have an electrically dependent airplane but I never imagined I'd need that many connections ...

Like Dale, I find that too many ends up being not enough. Two lugs per screw is really just a serving suggestion.
3/8 is massive. I wouldn't go bigger than #10, but I would support both ends with that design. Or mount it in the middle possibly.
