I "grew up" manufacturing under Mil Spec during the 1960's and learned all the how-to's as well as the not-to's. Even wrote our company QC
Manual all those years ago.
Recently performed a pre-delivery inspection of a drawbridge control system at a integrator's facility, and it was sad. They had minimal knowledge of workmanship and argued about every one of my criticisms and rework requirements. Things like (many) nicked conductors from stripping, crushed conductors where stuffed under terminal compression plates, lack of service
loops (although specifically required in the specs), and failure to make daisy chain conductors continuous independent of the individual device terminals the multiple conductors were stuffed under. I could go on, but if you know what I'm talking about, then that's enough to give the idea.
I set forth to buy and supply them with some general electrical control and wiring assembly workmanship texts and guidance specs, and, to my amazement, haven't been able to find any ... civilian or military. Couldn't even find
the NASA assembly specs I remember because NASA has grown so darn big I couldn't locate which offices might be buying assemblies.
Can anyone point me toward some helpful specs or texts covering this pre-1960 technology. I've got more data than I can handle on fabricating IC's and assembling zillion-layer PC boards (areas in which I have no interest) ... but how
about old-fashioned switches, push-buttons, relays, and pilot-lights?
