I've done the twisted together and the hammer smacking method before. The twisting worked the best between the two methods since the one of the metal was brittle and cracked easily instead staying attached when smacked the hammer, and neither agreed much with the reference. But one was easy and the other was fun. Being able to claim that the other one was doing highly calibrated delicate precision work was fun when asking the bystanders to step back, and then swinging the big hammer to smack the twisted joint.

The hammer idea would need some safety glasses, a quality hammer and a hard striking surface, which probably would likely exceed the $15 in total if those items are not already on hand. Although this is something I would not recommend for TC joints as I believe it does not represent a true weld, I have seen TC joints consisting of two wires twisted together into a spot of superglue. Does anyone have any thoughts on the legitimacy of this method? And, thanks for the comparison to MacGyver. However, he would’ve probably used some aluminum foil, paper, rubber bands and a couple of paperclips after stripping the wire harness from a junked car in the neighborhood (MacGyver’s cost - $0, as always).

If we're going to MacGuyver it, you can just strip the insulation off the ends of the two wires, twist the wires together, and smack the joint with a hammer to create a TC junction. -Ken A.

Just make sure the cap is safely voltage rated and polarity observed for the DC supply when charging. Also, common alligator clips that fit on the banana ends are easily replaceable as welding takes its toll. Please note that this set up will not produce controlled or consistent welds, but with a little practice the welds will soon become quite good. IHTH.
