I have decided to use PVC conduit in each wing to run the wiring for the wing tips, pitot heat, etc. So I have to find a way to run and secure the conduit. What better way to do this than what's in AC 43 for certified aircraft? Is it the lightest and quickest way? No, but it's a proven way. Anyway, I am am riveting a small lightweight 1/8” thick piece of angle to the main wing rib and securing an adel clamp to that with proper AN3 hardware. It is insanely strong and secure. Two 470 rivets to secure the angle will suffice.
