Just logging a little time to reflect the research on conduit and holes in wing ribs. I've referenced the Vans information and still don't quite get it. Well, I understand it, it just seems limiting compared to what I've seen people do.

I get upsizing the tooling hole closest to the spar for the pitot, but I'd like to run the AOA up there too. The W-1010 has a second hole in the bottom of the rib near the pitot hole and some have assumed they are free to drill a similar hole in all of the W-1011 ribs. Even if that was ok, I don't like that position because it will make riveting bottom skins more difficult. I prefer an additional hole above the existing tooling hole, sort of mirrored about the chord line. I've seen people do that, but again not covered by the Van's guidance. I will check with Van's I guess, but for now will assume that is acceptable.

For the main wire run, I just don't have a good feel for what will fit in a 3/4” conduit. Is one enough? Probably, but some people seem to run more.

And do I really want conduit anyways? Seems feasible that if you had to you could pull wires through the bushings.

To hedge, I'm leaning toward installing the snap bushings in the recommended holes per the instructions and then running a conduit in each wing. I'll use the conduit for my primary wiring and the snap bushings will actually serve as the future spare in case I ever need it.

If I'm running conduit - what to run? Probably some thin wall PVC or PEX tubing. There are easy PEX joist connectors that could blind rivet to the ribs at the lightening holes. Or Vans conduit with a one hole rivet connector similar to what I had for the VS, but that would use zip ties which I'm not excited about.

Conduit allows me to defer the decisions a little bit. What I need to know now is what to drill in the ribs. I think I will pretty much do it per plans, except drill an extra hole for AOA pending Van's approval.

4/22: update - going to drill an extra hole in the left ribs for the AOA in line with and above the pitot hole. Then upsize the existing hole to 3/4” for installation of Vans conduit. In the right wing, where most of the avionics are, I will go ahead and upsize the pitot hole to 7/16” and install snap bushings for additional capacity if needed.
