REPLY Once again I tend to agree with Norm. Sadly many people still have to contend with insurance surveyors and conforming to "standards" and otherwise complying with some arbitrary regulation on how things must be done. ABYC for example does not permit soldered only connections. The one exception being battery cables on the battery clamp end. Curious, why allow it on the most critical location but then prohibit it anywhere else. While working as the Quality Assurance Manager for an electronics company selling equipment to the government and military I had occasion to challenge this solder only versus crimp argument. I had the production people prepare a number of crimped connections and an equal number of soldered only connections. I then applied the pull test as per the standard to determine the exact breaking point of the connection. To everyone's surprise the wire sometimes broke before the connection did. The test jig provided an exact reading of the tension pull just before the wire broke. It proved that soldered connections properly made was equal to crimped connections and in some instances exceeded the breaking strength of the wire involved. Even so we still had to conform to the "standard" <smile> The government inspector said he did not have any authority to over ride a standard called up by contract. So yes I think Norms soldered connections are fine. I bet they will probably still be fine when the boat itself is eventually scrapped many decades from now. Steel doesn't last forever. Soldered copper does.
