 Posted: Sat Apr 11, 2009 11:00 am Post subject: Crimping lugs onto CCA Cable |
 |
|
HI All,
I am moving the battery in my Europa further aft and I have decided to remove the welding cable and use the copper clad aluminum cable that Eric sells.
I noticed a thread a while back discussing the issue of soldering wicking its way up the cable so I decided to crimp my lugs instead, however I was wondering if there is any issue with the aluminum "creeping" over time.
The reason I ask is that there was a trend about 30 years ago to use aluminum cable in heavy industry, but they found the cost of ongoing maintenance out weighed the costs savings of the cheaper cable.
Anyhow, any input or best practices would be appreciated.
Thanks, Paul

Paul,
Solder wicking into the cable is only an issue if the cable is subject to vibration. If the cable is supported about 3 inches from the soldered terminal, then it will not vibrate or break, located far from the engine. The cable could be clamped to the battery hold-down bracket or adjacent structure.

Paul,
My website has instructions for crimp+solder being the preferred method, but certainly there are people who only crimp the CCA cable.
By the way, if you search Ebay for "hammer crimper" you will find an amazing deal: Hammer On Welding Cable Lug Crimper - NEW! LENCO # 840. You can have one of these for about $20 delivered! They are the perfect tool for this application.
As I have mentioned before, plain aluminum cable has a vast and complex problem history. Engineers spend their lives on the problem, but CCA has had NO PROBLEM HISTORY at all.
I have sold more of this to military aircraft builders than I have ever sold to the Experimental community. I also have sold this to NASCAR, Indy, and dragster builders. The Tesla Electric car uses it, as does Airbus and Boeing.
Please read my technical notes on the subject:

Hi Eric,
Thanks for your reply. In particular I was looking for assurance that "creeping" or "flowing" of the aluminum over time was not an issue. It seems like there is enough in service history that tells us it isn't a problem

I was the person that had the problem with the solder wicking. After
I followed Bob's advice, the problem disappeared.
The main thing was to ensure that I had plenty of copper nails stuffed
into the opening, to make it as tight as possible.

I understand the I could also solder them and although it is possible with
the correct technique to stop the solder wicking down the cable it isn't
particularly easy to prevent it from happening.
Thanks again, Paul
