Magnetic Precise PCB Probing

In addition to PCB vices , I immediately planned to make these probes. I didn't find the ones I wanted. And yes, all the details are very small and require special processing, but the result is worth such an effort. For making probes, I bought stainless steel spring wire. Specifically, in my case, a wire with a diameter of 0.7 mm will be used. For insulation, a heat-shrinkable tube with a diameter of 0.8 mm is used, its shrinkage is almost three times. Attaching the wire to the probes with simple soldering will not work, at least I do not know such a method. I would be grateful if you tell me such a flux or something else. But there are at least two ways out: the first is crimping into terminals; second - pulse welding. I chose the second method, the more there is something to use. Also, the probes must be sharpened. At one time I made this wonderful tool , which I still use today. But you can use what you have. But keep in mind, this is stainless steel, it is difficult to process
