Despite what they said, Wiremasters shipped UPS instead of USPS to me
though which added another $50.+ brokerage etc.... Probalby cause they
put the wire on spools and used a huge box to ship. OTOH their price on
RG400 was excellant.
You can use up a 100' roll pretty quick just running out to nav lights
and wingtip strobe power supplies. 95% of my wire is #18 or #22.

Jeff,
I like your strategy, mix it up a bit. I'm doing the same as I am sick
of white or in the real oldies, fabric mixed in between. Asking about
preference in color on this board is akin to asking what type of ice
cream everyone likes :) Logically I like the concept of associating
color with function. GPS is blue, com is orange, audio is green, ground
is black etc. Everyone will have their own preference. What works best
for you is what makes for good logic in your mind. Even if you follow
well thought out color patterns, some good labeling is always helpful.
Of course documenting your work will help you a year from now when the
colors all blend together.
BTW - Does anyone know where I can get one of those deals (I don't know
what they're called) the shops use to label the nice yellow shrink
covers they put on the ends of their connections?

Looking under the instrument panel of my 1970 Cessna 172, I had
believed that all aircraft wire was white. Of course this has made it
extremely difficult to follow a particular wire somewhere.
I had planned to use a little spray paint to identify wires, but
looking at the web sites, the Tefzel wire is available in a nice
rainbow of colors.
So should I purchase a variety of colours and end up with too much of

If so, how would I determine that the paint would not degrade the
insulation over time ?

I'm using the labeling method Bob suggests clear shrink tubing and
computer printed labels. Keeping a wire list in Excel or something that
lists the labels should make future maintenance easier - especially if
it falls to someone else.
Anyway, I just started but it seems to work. B&C sells a labeling 'kit'
with the needed sizes and amounts of clear shrink tubing. Cheap and easy.

I just did a quick search on the web and found several sites catering to
inexpensive plans and components for such crystal radios. I realize that
you are probably trying to keep your expenses low, but these sites may be
helpful in getting what you need in the quantities and timeframes you need.

Barring any last minute changes, I've completed the wiring on my Delta,
aft of the firewall. Here is what my wire rack look like now:
http://ernest.isa-geek.org/Delta/Pictures/WireRack.jpg
I bought 100ft of everything except the RG-400, 8AWG and 4AWG. I got
50ft of each of those. The 8 and 4 was bought seperately, but the total
of everything else was $162.

There is quite a lot of Teflon insulated surplus wire available on eBay
including
shielded wire at a fairly low cost.
It appears to be high quality -- silver plated wire -- with high temperature
limits -- 200 C.
It is my understanding that smoke from teflon insulation is not quite in the
same category as smoke from tefzel.
I am gratified to hear the defense of tefzel, since Bob's arguments make
sense.
I know that tefzel is a very tough insulation material. Other than that, are
there any other
reasons that one might prefer tefzel over teflon?

Point well taken. My orginal (and standing) goal was to put together a
communal kit that all the builders in my chapter could use. 100ft of
everything was just a feel-good number for a first attempt. If I were
to do it again, I'd buy much more of the 22AWG and much less of the
thicker wires. I'll need to order more of those for the next builder,
but I'll have the thick stuff for a long time. Of course, at
WireMaster's prices it doesn't hurt so much to have all that extra stuff.
I made up a spreadsheet that calculated the wire loss for each size I
bought. Inputs were the load and total wire length. The loss value
turns red when it is greater than 5%. Yellow when it's between 3 and
5%. I stayed away from the yellow, and there was practically no call
for 16AWG or thicker (though, I did oversize a few for motors). One
thing I've done is to use LEDs for practically all the lighting, so that
cuts down on some of the big wires.
I should have bought a roll or two of 22AWG shielded cable.

Go with the multicolors and team with some other builders to limit cutoffs.
If that doesn't work, go with the paint, but buy the new paints that are
designed to be used on plastic. "Fusion" is what they call it, I think.

Teflon jacket with silver plated conductor is actually pretty poor wire for
use in aircraft. Silver plating isn't good in high vibration areas as it's
brittle. Teflon wire is slippery, has poor cold flow tendencies, etc...
Stick with Tefzel and you'll be fine. Ignore the surplus teflon as well.
It's one of those things that's sort of "pennywise....but...".

Jeff,
I have been doing avionics on and off for the past 20 years. Back in
the day we only had white to work with. So we had to use a labeler
(wire printer) which is not practical for the home builder. Other
alternatives are using shrink tube. Use very small white and small
clear, write on the white and shrink it on and then clear over it. You
can just use the white if your not going to be dragging the wire around
for a long time. All that being said, I would use the colored stuff at
what ever the cost! It is such a time saver it pays for itself several
times over. Doing your drawings are a breeze with color wire. Just
write notes as you go and converting them to a final drawing is a snap.
When I did my most recent airplane a Lancair Legacy RG, I ordered 100
feet of every color in 22awg and 18 awg. I ordered 500 feet in red,
black, and one other color in 18awg. As I was getting short on certain
colors I would make a small order to keep from running out. In the end
I had some extra but not much and you always need wire.
Mike
Ok, Tefzel wire it is. Wire Masters and Stein both appear to have

If so, how would I determine that the paint would not degrade the

That's an awfull lot of some of the wire, but probably tight on a few
others. Couple of suggestions:
All power wires red (down to about AWG14 which is the largest size most
people stock in colors), Ground wires black, lighting wires yellow,
signal wires white, etc... Pick a scheme and stick with it. In our
shop we pretty much do that as standard practice.
Also 50' of AWG8?!?! Normally on an a 2 seat RV you'd see about 4-6'
total!
AWG20 you'll hardly use at all outside of the panel, and then the amount
can vary dramatically depending on what you wire. AWG16 is also
something you may use a lot of or use almost none of...depending on
equipment...same with AWG14. AWG18 and AWG22 are the big ones!
The suggestion presented previously about twisting the Dynon wires
brings up another point....SHIELDED WIRES! Most of the EFIS's with
remote mag's recommend them to be shielded (especially Dynon). If
you're going to install a dynon or AFS unit it would be wise to use
shielded wire now while you can instead of trying to fix the gremlins
later.
Same goes with audio wiring. The jacks, radio, intercom, etc.. should
be wired with shielded wire, and lots of avionics also require shielded
wire.
I'm a fan of people buying lots of wire :), but the best approach is to
conceptually decide what is going to be in the plane (lighting,
avioincs, engine, batteries) and then decide. Your requirements may
vary by literally many hundreds of feet just by the avionics alone.
Also, if you don't wire up your own panel, then you'll need much less
wire.
I hate to tell you this, but no matter how much stuff you buy up front
in your initial shotgun blast, you'll still likely be left needing
something you forgot....it's just part of building - UPS loves it!
Just my 2 cents as usual
Cheers,
Stein

Bob (and anyone else who has wire length data for their RV),
So you had more than enough ordering 100 feet of each color and gauge
you mention below, or were these multi 100' spools? If I was to simplify
the number of gauges to keep in stock, what would you recommend? Aside
from some situations (alternator, etc), would 18 and 22G cover a typical
RV? I ask, as I am getting ready to place an order and want to try and
cover the whole project (RV-9A, Dynon glass EMS/EFIS, setup for VFR day

[/quote]
Call up Wiremasters. The sell in bulk and don't mind homebuilders.
I don't have their number or my receipt handy, but I think it was about
$150 I spent. I got enough spools of multi-colored, tinned-copper
Tefzel to wire my whole airplane and have enough left over to do most of
the next. I may have been able to find quality PVC for less, but I
would probably had to go surplus. I bought 100' spools of 22AWG (red,
green, white, black), 20AWG (red, green, white, black), 18AWG (red,
green, white, black), 16AWG(white), 12AWG(white). I also got 50' spools
of 8AWG(white) and 4AWG(white). That covers everything but the battery
cable, which I covered with welding cable.
The multi-color isn't an absolute need, but is nice to have. It cuts
down on some of the labeling requirements, especially when bundles of
related wires are twisted. Just chuck one end in the drill, pinch the
other end and squeeze the trigger until the bundles starts shrinking.
For instance, the magnetometer connects to the Dynon EFIS with a power,
ground and two signal lines. Red, black, white and green (respectively)
and it doesn't really need a label at all; though it does get a big
"magnetometer" sticker for good measure.
The rack of wire is incredibly useful when the time comes. Just run the
wires and not worry about estimating how much of each is needed. It's a
good item for a builder group to have. Pay for what you use, and then
pass it on to the next guy. Reload with a multi-hundred foot spool when
one runs out.[/quote]

I doubt you could ever overestimate on just wire cost enough to justify
someone else doing it for you. It's a matter of how much you want to pay for
convenience. After wiring my first I realized that having a big spool and
ripping off a generous extra for each wire would save a lot of time, worry
and frustration. I found a surplus 500' spool of 20awg and am using it for
most everything. I bought plenty of the other gauges and types I needed. The
wire was cheap and the convenience is wonderful. On a $70K aircraft the wire
cost is peanuts regardless of waste. On the other hand, I'm using shrink
tube markers which far exceed the cost of the wire itself. But they sure are
pretty and will be well worth it in years hence for troubleshooting. You pay
for convenience in some form or another

Good Afternoon Greg,
I purchased and have used a shrink tube sleeve style wire marker. However,
I find the additional bulk at the terminals to be objectionable and I really
miss the convenience of having markings along the entire bundle length when
doing trouble shooting. Does anyone on the list have any experience using a
Kingsley wire marking system either directly or through a service provider of
some sort?

Definitely agree here.
Plus, after you have wired an airplane you may find that you are the
wiring "guru" around the airport, and as such have opportunities to help
other builders/owners with minor (major) wiring projects. Having tools
and materiel may provide you with ways to gain good will and to barter for
other things you want...

I would prefer wire stamping too. During my airline days, the shop stamped
all the wires in the harnesses they built. I've heard tales of folks picking

Good Evening Greg,
I know a couple of folks who have WWII era wire marking machines that they
bought on E-Bay. It appears that the big item is to get the appropriate type
and fixtures. That can cost a bundle. I do have some inquiries out and about.
Hopefully something or the other will bear fruit!

Teflon wire is a pig to strip without very sharp tools or hot knife
(Stein - how about adding hot knife strippers to your inventory?). The
risk of cut wire strands is very high.
It's a bit like working with Titanium rather than 4130 or Aluminium.

Don't forget...the reason that those machines are on ebay is because most of
us that had them for years have now sold them...can't use them on airline or
military wire anymore! For most aerospace applications you're now required
to use something that is not destructive to the insulator.
We had one for years but finally sold it, because none of the airlines,
military or OEM guys will allow stamped wire anymore. Now everything has to
be labeled in a non-destructive manner (lased or inked).
You can still get the ribbon, but the type/dies/piece parts is a whole
'nother story. The machines are HEAVY, somewhat clunky and for the average
home / casual user just not a good solution at all. Buy a nice lable maker,
heatshrink printer or clear heatshrink and be done with it. You're looking
at over $150 PER DIE (1 die needed for each wire size) and even more for a
set of type &/or wheels.
Cheers,
Stein

Thanks guys, I appreciate the response. Yes, I can still remember as a kid when
I pulled in the magical radio waves without power. I am trying to keep my cost
down as the cheapest I have been able to find the variable air caps is about
$10 each. That will unfortunately break the piggy bank...but if anyone knows
of a stash of them anywhere I'd sure like to hear of it. I would like to get all
the kids to build one, but it is looking more like a need to pair up.
Thanks again,

Dan,
I just did a quick search on the web and found several sites catering to
inexpensive plans and components for such crystal radios. I realize that
you are probably trying to keep your expenses low, but these sites may be
helpful in getting what you need in the quantities and timeframes you need.
Just some thoughts....

Sorry. Threw mine out years ago, but after my kids made it work again.

| Subject: | Source for Strobe Cable |
Hi 'LectroFolks,
I'm looking for a source for multiconductor cable to be used for installing
Whelen strobes. I need the cable to go from the power supply to the strobe
units/heads, not the power lead.
The current "installation" kit I had (and used on another airplane) uses a
Belden cable consisting of 3 - 16ga. conductors with a shield, insulated
with (I think) some kind of rubber/vinyl. I don't think it's teflon.
I would like to find some additional cable without buying another seriously
overpriced "installation kit" which includes connectors I already have.
I probably need about 50 feet, but I'd buy more if it's semi-reasonable, (up
to 100').
Does anyone know where I can find this kind of cable? The 16 ga. spec is
probably seriously overdone, since the high amperage load is extremely
intermittent, but that's what Whelen uses, and this particular installation
is going into a certified Cessna. (I used the other cable kit in my
Glasair.)
I've looked at SteinAir, and they don't have anything in cable bigger than
20 gage, and are really short on multi-conductor stuff.
Thanks,
Ron Cox

Ron,
Check http://strobeguy.safeshopper.com/32/1922.htm?248 and see if this
will do the trick. Give him a call first to make sure the wire gauge is
what you need.
