Simple K2 Question

k0wa@swbell.net

Reading about K2 Power Cords...is there anyone out there making them that look "commercially" made.  I have made two sets of power cords (K2 and the KAT100) and after I am done they look like "crap."  They look bad.  I guess it is the way I am trying to put in fuses in the line and don't have a good way of doing that.

Anyone out there making them for the K2 Community?

Re: Simple K2 Question

Lee,

What I have done in the past sometimes is to purchase a 'factory' cable
of your choice and then put the ends you want on it. This way, you get
more or less what you want. I do this all the time with keyer paddles.
Ppurchase a cheap 3 conductor stereo cable, hack it in half and now you
have two 'factory' looking ends. Solder on a few lugs and it looks and
like it was 'meant to be'. I've done it with power cables as well. Once
in a while I'll come across and a power cable I don't need in one
application that would work very nicely in another. I put the ends I
need on it and the fuses I need in it and now you have a nice cable
setup.

73,

K2 power cables source

Ken Kopp
Isn't this what old wall-warts are for ... the cords?

Is there anyone out there who has -NOT- had satisfactory
results with Anderson Powerpoles?

Ken:

I have found with power poles that it is important to use the right
crimper. I have never ever been able to get a good connection with
the "plier" style crimper that West Mountain Radio sells. Also, I
have found the West Mountain ratchet style crimper to be good only
for smaller wire sizes. For the higher current connectors into No 12
or 10 wire, I find that only the genuine (and not inexpensive)
Anderson crimper produces good connections.

That said, if you use the right crimper, power poles are a breeze.

I have a Powerpole connector based power bar that has the fuses in the
power bar, so I don't have to worry about that inline fuse connector
myself.

What I would suggest is using black (or red/black) lamp ('zip') cord,
and covering the inline fuse connector's wire leads with heat shrink
tubing. Also using a short amount of heat shrink tubing as strain
relief at the end connectors, rather than electrical tape.

Of course neatness is easier said then done.

I disagree with that statement.  The inline fuse is to protect the lead
as much as anything.  I use the same sort of setup as you Michael but I
would not dream of fitting leads without inline fuses.

So far, I've had quite good results using the West Mountain
ratchet-type crimper on
wire gauges up thru #10. In fact, I used it within the past couple
days on a cable
for a local, using #10.

Success at larger gauges may depend somewhat upon the gauge of the
stranding. The
stuff I used was quite flexible and utilized MANY strands of probably
#26 or finer
gauge wire.

A local who also has the West Mountain ratchet-type crimper has one of the dies
in the crimp head fracture when he was trying to crimp (I think) some #10 wire
which was made from much larger gauge wires.

I've had no problems with smaller gauges of wire either.

I've had LITTLE(!!!) success using the 'plier' style of crimpers at ANY gauge!

Tom:

Interesting insight about No 10 wire made up of very fine strands.
The failure more that your local friend has run into with No 10 is
exactly the failure mode that I've run into as well.

Caution to all list members, as Tom also points out: DO NOT WASTE
YOUR MONEY ON THE WEST MOUNTAIN PLIER CRIMPER.

In reply to this post by AC7AC
I maintain my own fleet of radios as well as those of the fire
department in which I am the Safety and Comm Officer. The wildland fire
fighting vehicles probably subject the equipment and connections to the
worst case scenario for vibration.  I've learned to use a small butane
torch to solder the PowerPole connectors.  This has put an end to power
connector problems and is really easy to do once you get the hang of how
much heat to apply.

Steve,

Just curious, are you talking about the PWRcrimp tool?

http://www.westmountainradio.com/PWRcrimp.htm

I've had nothing but great results with it so long as I have always used
the proper die-set for the job at hand.

Jeff:

No. The one that both Tom and I are complaining about is a device
that looks like a pair of pliers with crooked jaws. I notice that it
is sold by PowerWerx and not West Mountain.

As we've been discussing, the West Mountain PWRcrimp is ok for
anything smaller than No 10, but you might want to practice making a
few throw-away connections before you try doing it for keeps.

If you're trying to crimp number 10 wire, unless you are very
experienced (and lucky) with the PWRcrimp, you need the genuine
Anderson crimper to get number 10 done right.

  I have limited eyesight in that my close-up eyesight is
  monocular, not binocular - no close-up depth perception -
  so a soldering iron or torch is a deadly weapon in my hands.
  That's why I had my K2 built by a local builder.

  I do crimps very well, partially by feel.  That takes skill but
  I do it.

At work, we replaced all the welding cable
(lots of fine strands) with very stiff wire made
up of fewer thicker wires.
I was told the welding cable would not give
a reliable crimp....
48 volt hundreds of amp stuff...

You need the correct size die that crimps on all sides,
along with enough force to crush the wire.

I just soldered my connectors, I never liked crimps,
especially unprofessional ones....

RE: K2 power cables source

Werner & Denise Haschke
 I have always been told by the ex Air Force people that crimps were the
only method for any high vibration cabling. Something along the line of
changing the temper and also creating a stiff spot in the wire that could
not allow the wire to flex and this would be where the wire would break. Of
course, sitting on the bench this would not apply, but may apply in mobile
use or some portable applications?
Anyway, if you were in an airplane, you may want to check for proper
methods.

My two cents for what it's worth.

The day before the BS8 ( scarborough expedition) went on the air...
my rotor stopped turning...

The motor inside the M2 2800 had become loose from its mounting, and
had shaken the solder connection enough to snap it.

I agree that #10 is a challenge with the West Mountain rachet tool;
however overall I like crimp. But without the 50$ tool I agree solder
will probably is the best overall way to go. That plier (GB) crimper
, even after a ton of crimps ( practice) does not
reliably yield good crimps.

Re: K2 power cables source

AJSOENKE
In reply to this post by Ken Kopp
The tool you are referring to was a design originally made by T&B  (Thomas
and Betts) and for many years it has been an industrial standard. It  works bets
with T&B crimp terminals and it provides crimping by embossing a  deep
impression on the back side of the terminal port. It is important to know  which
side of the terminal to emboss. On terminals made by T&B they use a  zig-zag
pattern to form the joint along the barrel. That seam is along the top  side of
the terminal, and you don't want to breach it by crimping on that side.  So the
dimple on the tool is placed along the back side which is smooth. There  are
definite advantages to this method. I still have my T&B crimper that was  given
to me by a company that made traffic signals and controls. I still use it  
frequently being that T&B used hardened steel that hasn't dulled or lost its  
shape after 40 years. The best thing was that I never had one of those crimps  
pull  loose. The cheap kinds that cross crimp the wires can all be pulled  
loose before the wire breaks, and this is because they actually weaken the wire  
where they squeeze it cross-wise along a narrow gap. Using a tool that crimps  
longitudinally will give a superior crimp because it applies pressure to the  
wire over a large area and distributes that force along the entire inner  
surface of the barrel.  T&Bs zig-zag seam is welded to maintain the  integrity of
the terminal. The West Mountain tool works in reverse, applying a  uniform
(Hex) force from the outside inward. These are both superior methods to  
squeezing a couple "nicks" in a  thin folded barrel.

Understandable, though with 6000 K2s in the field...

I also asked Joel at The RF Connection (http://www.therfc.com); he's made a
number of custom cables for me in the past. I asked about the 16g PP cables
we've discussed for a K2, w/ or w/o fuse holders:

So ... your path is clear :-)
