Hello!



I have one wing ready to skin and have run a bundle of wires from the root out to the tip through the leading edge. The wire may be used for a heated pitot tube (~3' from the root), landing lights (~1' in from the tip), and a tip nav/pos/strobe combo. I will most likely not install the lights and heated pitot until after hours of flying, if at all. So, what are some good ways to tie off wire that won't be used?

 

The first wire I need to figure out is the one for a heated pitot. My bundle goes through the forward of two lightening hole and the pitot tube is located several inches back near the main spar. If I make a few loops of pitot wire and tie it to the bundle, I wouldn't be able to reach it through the access hole, which is only 2". So I'm thinking it should be real close to the access hole, maybe even on the pitot tube assembly itself? Again, it's not a heated tube but would be available if I switched it over to one in the future.

 

Then there are the rest of the wires that end at or near the tip. For now I've coiled them a few times and cinched down a cable tie or two there for the time being. I'm not in a hurry to get this location figured out, because I'll have access to it after the wing is skinned. But the pitot tube wire needs to be figured out in the next few days.



Cheers,

Dan

Dan,I ran a piece of 3/4-inch OD, 5/8 ID polyethylene tube the length of my wings so I can pull the wires when they are needed.  That begs the question of a heated pitot.  I figure that if I REALLY need a heated pitot, I can use a soldering iron through an access port to melt a hole in the conduit.

Dan,

 Consider doing as Roger suggested and instead of running the wires, run a  pull line through the conduit to use later to pull the wires through.   Also, you can use a file to make a nice, smoothed edge hole in the  conduit.

 You can partially see what I've done at http://www.rv-8a.net/2006.htm and  scroll down to 8 Apr 06 and 14 Apr 06.  You can see the conduit in those  photos and how I fed lines into them.

 Regards,

 Stan Sutterfield

Thanks for the replies, guys.



I've already got the wires routed without tubing. What it really comes down to is how to secure the loose spare wires at their ends before they are hooked up. With a tube this wouldn't be a problem. I suppose I could wrap and tape the heater wire around the non-heated pitot tube.

I'd cut it off fold it on itself, stuff it in some heat wrap and heat shrink the wrap on it. That should hold it and eliminate the messiness of electrical tape "goo"

This won't help the original question, but if you have run conduit then remember this trick.  A vacuum cleaner stuck on one end can be used to "pull" a string through the full length of the conduit from the other end.  Then just attach the wires and pull them through using the string.
