...been looking for the cheap wire (ala cheap
as mentioned above) at a narrower CONSISTANT diameter
thought I’d found the jackpot (such as in the fatter electrical (residential etc.) scrap) in coax...evidently not exactly
I got this coax at habitat for humanity restore -was very proud of myself
so beware, much coax has a steel core...this too may explain the brittleness I experienced that one annealing ago with thinner gauge..
what to do???
first I noticed that the end of the wire did not look solid copper —dug some, it’s maybe only 70%....
next test: strong magnet
so make sure you take a strong magnet just in case
not all coax has steel, some is solid Cu
..this pic ain’t fantastic, but can kinda make out the steel core, btw coax is ~just shy of a US dime in thickness
