Richard,
Yes, the WIKI tells you why but the Navy document tells you how. That, I have taken note as all the conventions in the document I learned at Raytheon. I re-processed the html into a pdf. Easier to send and read without a browser...
Just a note, harnessing is not for a radio that has been functional. Altering wire positions and bundling certain connections can cause oscillation. In "boatanchor" radios harnessing is designed in.
You might do some online searching as there is a four-wire textile covered cable used for lighting that would save the aggravation of finding the specific wires and wrestling with a braided casing. There is also cotton braided casing that can be dyed brown. That type of braid, as long as it is near to size can be hand worked to tighten around the wire bundle.
I had a dream, that when I retired I would set-up a specialty braiding mill. Capital was available so long as I did not have more than two or three employees. I HAD all the machinery in storage. But, it was the necessary bookkeeping and the mill SPACE that became the issue. Along with all the other requirements an industry has. My dream became a nightmare that fortunately I awakened too before it came a reality. What was the realty, I did however, set up one braider and one bobbin winder. What I can say from that trial run is that any custom braider WILL have a minimum time and materials costs. Especially if the yarn is not in stock. Winding 16 bobbins for a run takes at least 90 minutes, trial runs for tension and braid angle another 1/2 hour before even the first inch of cable is produces. Today's labor costs, I estimate that is roughly $500 in time and material before the start button is pressed. My dream from textiles hobbyist to mill manufacture simply vanished. My total expense during the "learning curve" was around $7,000.. It would have cost me some $150,000 for four years in a textile manufacturing college, but I would not have had any fun, I think I got a bargain...
