Do you just drill a hole in the conduit and pull the wires through. Do you put a grommet on that hole; do you just sand it smooth; do you wrap the wires at the exit point in tape or some other anti-chaff material; do you RTV the wires into the hole.
I used a small pencil type solder tool to poke a hole. Wires are wrapped with shrink wrap at the exit hole.

Exactly. And that's why my RV-3B project has no conduit.

Conduit in both wings. This is one where I considered the weight worth the ease of mx. Besides, I could personally afford to lose a pound.

I would only advise not to allow the wires to lay against the wings skins or other structures other than the bushings. I have seen wire insulation rub through over time due to vibration and cause shorts.

Default Conduit

We did the conduit, not knowing it was flammable. It was a terrible pain to pull through the ribs; if my wife had ever left me it would have been then. We would not do that again.

I am glad I have the conduit in my left wing. When I decided to retrofit the AFS AoA with the Dynon pitot probe, pulling the extra plastic line was a matter of minutes.
