Russ; There is something wrong in my writing or your translation of my writing.
The $0.99 motor shaft is a perfect push on fit for the #14 solid copper wire insulation. Radio Shack Part # 273-223. Yes it is solid wire and the 1/4" empty space is what slides on to the motor shaft. I have made dozens of them. Solid core, right? YES . Cut the wire to the 2 1/2" length before sliding the insulation back. > So 1/2" copper is exposed, right? Yes, 1/4" in the vise and 1/4" in air. Any bare metal will silver plate in just a few seconds. The stirrer is the copper filled plastic coated wire. "Ole Bob"
