Just an update......
After making about a dozen by wrapping, crimp tubes, and soldering.....soldering is at the top of the list; especially when making a few at one time. I'm using Super Easy silver solder/paste mix that has a melting temp of about 1200F. Just a TINY bit of solder/paste and a couple of seconds with the torch and it's done. Any excess can be ground off.
Soldering is stronger and much easier to wrap. Here's an avg looking joint; hopefully it will get cleaner and smaller with practice.
If I'm doing one; I'll wrap the wires; crimping goes on the shelf. By the time I get one done with crimping I can solder 2 and I don't have to worry about one of the wires pulling out of the tube.
