List;Sorry if I sounded a little harsh with my last post about hard wire bracing and ferrules. As an engineer, I'm usually more logical, analytical, and unemotional about these things. Let me rephrase my earlier comments by just saying that there are some excellent posts in the archive on this, such as Greg Cardinal's one from 2/28/01 explaining his investigations and comments. He also references an early paper on various wires, cables, and connections (available as a NACA report but you have to search for it with Google and get it off a British technical paper site. I just printed it out moments ago myself).The bottom line is that the typical wire and ferrule method produces connections that aren't as strong as the wire itself. My point was that that may be plenty strong enough and probably stronger than other links in the chain. Greg's bottom line was that pull testing should be done.I haven't done that, but it should be very easy to do.Oscar ZunigaSan Antonio, TX________________________________________________________________________________Date: Fri, 08 Oct 2004 12:38:52 -0400
