Has anyone used any sort of wing wiring duct for the menagerie of wires coming from the wing tip lights, antenna, auto pilot, etc.  If so could you tell me what and where to find it? Thx  CJ

Carl,

  

 I like the light weight stuff Van's sells.

An advantage of the PVC pipe, besides being inexpensive, light, and 

readily available, is the smooth interior which makes it *much* easier 

to push wire through the conduit. I glued a coupling to each end of the 

pipe outboard of the root and tip ribs to hold the pipe in place.

Look no further than the Plumbing aisle at your local Lowes Depot- see:

I think both ideas are great. The split in the product Van's sell helps with wire drop outs for autopilots, landing lights etc... I just used a vacuum cleaner, taped a ball of cotton to the wires and sucked them through the conduit. A small dab of anti-corrosive silicone holds everything nice and tight.

Most of the time wire doesn't like to be pushed.  If you have room at 

one end, use your shop vac to suck a pulling string through the 

conduit.  A small piece of foam or even a piece of paper towel tied on 

the end of the string is all you need.

A few thoughts:



1. If you use the thin walled PVC pipe (7/8 OD), you can slide the conduit 

into the wing *after* the bottom skin is on, so you don't have to worry about 

bucking around an already in-place conduit.



2. If you plan the location correctly, it should be possible to use a 

continuous piece of conduit that goes all the way from the wingtip into the 

center of the fuselage.  See http://www.our7a.com/20070331.html



3. As others have mentioned, the PVC conduit is smoother and may make it 

easier to slide wires through.  On the downside, it's heavier though.



Happy building,

To refine your cotton ball "mouse" (that's what we

electricians call it), use a baggie instead.  Make a

small balloon  in one corner and tie the balloon off

with a piece of string.  Leave long tails on the

string and tie the wires to the tails.  Poke a small

hole in the plastic bag near the tie.  Suck it through

with a vacuum.  The suction pressure differential and

the small hole inflate the bag creating a seal.  Don't

wrap  your fingers around the wire, because that

baggie balloon will fly though the conduit like a

shotand take your fingers with it.

What an awesome idea! I can't wait to try it... 



Thanks, I'm filing this one under 'Builder Notes' for sure.

Dave is right about the warning " Don't wrap  your fingers around the

wire, because that baggie balloon will fly though the conduit like a

shot and take your fingers with it."

I'll be the odd man out here and say that I prefer NOT to use  conduit at all. I use snap bushings through the wing ribs then a small piece of  spiral wrap around the bundle between the ribs. This lets you visually inspect  the wires, keeps heat from building up, is lighter weight, and lets wires exit  the bundle anywhere you like. Yes, you can reach inside through the inspection  covers to install/remove the 1-2" pieces of spiral wrap in order to change/add a  wire. I've used this with two RVs now and wouldn't consider any other way.  Lastly, any of the conduit mentioned gives off nasty fumes if it ever burns  which is why we use Tefzel wire. Why add another material with poor fire  qualities when you don't need to?

Ok, since I didn't want to be the only one here I waited for Randy to 

say something...  

I did the same thing; used snap in bushings and no conduit...  You can 

easily rout wires through the end of the wing and the access panels with 

no problem...  Why add weight when you don't have to!?

What I like even better than PVC pipe is the black plastic tubing for drip irrigation systems.  It’s 5/8” OD, with a very thin wall.  It’s tough, lightweight, and flexible enough to go around mild bends (it will kink if you try to go tighter than about a 10” radius).   I’ve used it both in the wings and the fuselage.

I used CPVC and 1/2 pipe suspenders. CPVC is thinner and stronger than regular PVC. It is intended for hot water systems. The 1/2 pipe suspension clamps are riveted to the edges of the 3rd lightening hole (from the back).
