I am getting to route wires, aft of the firewall, and was wondering what kind of methods guys used.  The first time I did this, 20+ years ago, the result was a spaghetti bowl.



I am thinking of hanging some loops of wire ties in various spots, then running wires along those paths.  When all the wires are in, I would secure with the cromagnum wire ties, rather than the more elegant lacing.  It's all hard to access and the ties are decidedly easier.

 

One recent post referred to wire loom.  Is that easy to work with?  What about making short conduits?



Lets hear you.

    Lay out your wire routes for finished bundles. Run

    some Nylaflow 1/4" tubing on little plastic wire

    bundle clamps. You can get the tubing from hardware

    stores and big boxes like Home Depot. It's used

    to plumb up ice-makers in refrigerators . . . among

    other things. The 1/4" clamps can be had from most

    'real' hardware stores . . . or you can simply make up

    a little band clamp out of tin-can metal. These are

    temporary. Install the clamps at the same attach points

    that you plan to use for finished bundle supports.

    Use bond studs, nutplates, etc.



    Lay your 'real' wire bundles up along side these

    Nylaflow road markers. Get a wad of el-chesso tie

    wraps from Harbor Freight to hold each new wire into

    place cutting off ties underneath new wires as they

    become surplus.



    After your bundles are all finished. cut out segments

    of Nylaflow and Replace throwaway ties with good tie

    wraps or string ties. Replace your temporary bundle

    support clamps with the real ones.



    This technique allows you to set the wire-way for

    bundles that are many strands from self-supporting.

    This allows you to apply finishing restraints in an

    orderly cutting the forms away as you go after the

    bundles are completely finished.



    You can also use heavy copper wire #10AWG solid

    ground wire is generally stiff enough. You may find

    other materials that will do as well.

It might be worth noting that the new self-sticking (double-

sided) velcro strips make excellent temporary, reusable

bundle ties.  When done with the wiring, replace them with

one's preferred permanent ties, and reuse the temps on the

next bundle being assembled.  And they are easily available

from your friendly local H.D. aviation supply store.

I found a very temporary type of "velcro" at the garden department of Lowes.  It is green in color since it is meant for use on plant materials. It is "sticky" enough, but not nearly as hard to un-do as regular Velcro. Great for temporary bundling.

 

 I also found a "plenum rated" type of Velcro that I used as a permanent tie in several places. This material is fire resistant and made for above-the-ceiling wiring (where it is required by most building codes) and in data centers.

Sounds like an excellent tip, Bob.  I even have some Nylaflow tubing in the hangar.



I'll start today.

Why replace the velcro, Dale?  What is wrong with leaving the velcro as 
	


the permanent attachment?

I just passed through the same dilemma. What to do, what to do. On my

bird the wings may be detached for fuel line maintenance or perhaps

transport at some point, so I decided to install one DB15 connector in

the fuselage to handle trim and wing lights which need to be loose to

detach the wings. 



I wanted to use the trailer type connectors but had no luck finding the

necessary 5-pole jobs (Lowes, Home Depot, Wal-Mart, Hardware, Pep Boys

etc.) so gave up and decided a good male/female db connector setup held

the most promise. I hope to never separate the two,  but you never know.

After initial run-up etc I plan to pull the wings and flush the tanks

out once more. I take the approach of doing everything for the sake of

future maintenance. If your fuel lines have connectors between the stub

and the wing that may be one more reason for taking the wings off to

replace hoses or fix a leak.



It's Murphy's law, what goes up will need maintenance when it comes

down.

Sam,

 I believe Bob's technique to be the best.  I did mine that way and it  was relatively straight forwarded - even for a beginner like me.  One  suggestion is that when you buy the el-cheeso tie wraps from Harbor Freight -  buy red ones or orange ones (or some other color you wouldn't want on  your plane's wiring).  That way when you are ready to replace them with  higher quality ties, finding the correct ones to remove and replace will not be  difficult.  Don't ask me how I discovered this.

Bob,

Good point. Max is 2 amps for either trim or led strobe lights, so I

should be ok?
