[Elecraft] 45A APP Crimper

[W0MU Mike Fatchett]

I don't think we are subjected to the same issues as a Nuclear plant.  I
have had numerous crimped purchased cables fail because of a lousy crimp job
covered up by heat shrink.

If you are working on very small wires with Anderson connectors I am not
sure how you could ever get it crimp right.

Why not trim off a few strands of the #10 to make it fit and then, if
necessary, cover with heat shrink?  Sounds much better than another
solder/butt joint and would have less resistance. 

While discussing APP's, I was taught that connections should ONLY be
crimped.  In the nuclear power industry connections that were just soldered
or soldered and crimped were rejected by QA as they would fail due to
vibrations, movement, etc. at the transition from the soldered area to the
unsoldered portion of the wire.  Any that I have ever made have always
failed at this transition.  Essentially ALL connections in the electrical
power/distribution industry are crimped for this reason. and they handle
many more amps than a K3.
