The conduit has already proven its value as I decided to change some wiring after the initial installation. This was simple with the conduit and would have been major surgery any other way. One suggestion for conduit users,,, place a blob of weatherstrip adhesive at each place where the plastic conduit passes through a rib. Over time, the small amount of vibration against the sharp rib hole can wear through the conduit. A drop of adhesive eliminates the vibration. ________________________________ Message 3 _____________________________________ Time: 12:37:15 PM PST US From: "Terry Hobert" Subject: Re: RV9-List: wires in wings --> RV9-List message posted by: "Terry Hobert" I ran the conduit through the lightening holes. At each rib I would cut a piece of conduit about 2" long slice it lengthwise and wrap it around the conduit where it would meet the edge of the lightening hole. I then deilled a #40 hole alittle away from the edge of the lightening hole and put a small tie wrap throught it, I then put a larger tie wrap 90 degrees through that one and around the two layers of conduit. This holds it secure. I then dropped of wires at the aileron bellcrank (for auto pilot and pitot heat if used) continued on and dropped off wire for the landing light and continued the cable for the position/strobes on to wing tip. Dito on right wing w/o bellcrank drop, but have landing light in both wings and etc. Could send picture, but pretty straight forward.

Says it can vibrate thru the metal, even steel. The A&P who restored my Interstate Cadet says the same thing. I don't know if this is true, but both of these guys are top notch mechanics, so I take their word for it, especially in regard to aluminum. You might bend up a small aluminum bracket, attach that to your rib with a rivet or two, then attach the conduit to the bracket with a ty wrap cradle (p. 397 of Spruce's catalog) or an Adel clamp.

They are subject to heat degradation as well a vibration, and both conditions exist inside the wings over time. Pulling a small radius with a wire tie also reduces it's strength at the "gripper" because of the sharp angle entering the tooth section. I have had some fail under these conditions. Detecting and replacing broken wire ties inside the wing would be pretty difficult, and having the Aileron Push Rod chafe a hole in a wire would not be good. Adel's (MS21919 Cushion Clamps) with mechanical fasteners (bolts) and self-locking nuts are much more reliable, even if they are more expensive, complex, and heavy. Because of all these issues, I chose to run my conduits through enlarged tooling holes in the ribs.
