I'd use smooth conduit. Either regular plastic electrical conduit or, as Joe suggested, something like lightweight plumbing tubing. I'd suggest 3/4" or 1" if it'll fit. The corrugated stuff is good for wrapping around wires that are already in place but I find trying to feed wires through it later to be a pain. The reason for the larger pipe is not necessarily so you can cram more wires in but because the extra space also makes it easier to pull or replace wires later. --Rick On 1/1/2017 3:08 PM, Kent or Jackie Ashton wrote: > > Looking at your wings, I think I'd put some 1/2 to 3/4 auto wire loom protector in the wings, with zip ties so the wire does not work itself out of the split in the loom protector. Leave a nylon string in the protector that you can later use to pull wires. Later on, you can push a stiff wire through the loom protector and use it to pull wires. The loom protector is lightweight but will protect them from abrasion. > -Kent > Cozy & Long-EZ builder > >> On Jan 1, 2017, at 1:44 PM, GTH wrote: >> >> >> Hi all, >> >> Best wishes for 2017. >> >> What could be the dimensions of the conduit for the (nav/strobe lights, magnetometer, etc.) wires in the wing of a a composite aircraft ? >> There is plenty of room in the empty leading edge, but obviously the passage is too large and some means of attaching the wires seems in order. >> Any opinions on a practical way to use this long empty passage for wires ? >> Thanks in advance for your input, >> -- >> Best regards, >> Gilles >> http://contrails.free.fr ________________________________ Message 3 _____________________________________ Time: 10:38:43 AM PST US From: Subject: RE: AeroElectric-List: Best dimensions for conduits Leaving a "tied-off" line in the conduit to help pull a new wire through is a great idea. But remember that when you use that line to pull the next wire through, you need to also pull through another "spare" line to tie off, awaiting your inevitable "next" wire pull... Of course, I learned this the hard way... (Long story involving a lengthy conduit run from house to workshop, and a new welding circuit for the shop... Sigh.)

Fixing it inside a finished wing would be a problem. Wouldn't want it free to move. Jan de Jong On 1/2/2017 6:16 PM, Rick Beebe wrote: > > I wouldn't. I'd use smooth conduit.

This works best in conduit under a couple of inches in diameter, and where the conduit isn't already stuffed full of wires. It definitely won't work in a split loom. Another alternative is to disconnect a wire that's already installed and use it to pull through a replacement for itself along with the new wires (and a pull string for the future).
